Looking across the barebones kits on the market in 2026, the pattern is clear: the best hot swappable custom mechanical barebones kits solve the gap between off-the-shelf gaming boards and full custom builds. You want to choose your own switches and keycaps, dial in sound and feel, and avoid paying for parts you will replace anyway, without dealing with soldering or hunting down a compatible PCB, plate, and case separately.
What separates a good barebones kit from a frustrating one is not marketing but execution. A well-tuned gasket mount should feel soft and consistent rather than hollow or stiff, hot-swap sockets should hold switches firmly with no wobble, and south or properly diffused lighting should work with your keycaps instead of fighting them. The best kits get those fundamentals right while leaving room for personal tuning through switch choice, foam, and keycaps.

9. Keychron Q2 Barebone (65%, Wired)
The Keychron Q2 is the kit many enthusiasts point to as the first “real” aluminum custom keyboard worth owning, and the barebone version is a clear step up in build quality from the plastic-cased kits above. The case is CNC-machined 6063 aluminum that is polished, anodized and sandblasted, so it feels dense and solid on the desk in a way the GTSP and GMMK kits do not.
The Q2 uses a 65% layout with 67 keys, keeping dedicated arrow keys and a small navigation column while dropping the function row. Keychron calls its mounting “double gasket”: gaskets around the steel plate plus silicone pads between the top and bottom case halves, which cuts the metallic ping that cheap aluminum boards often have. Kailh hot-swap sockets accept nearly all 3-pin and 5-pin MX-style switches, the RGB is south-facing, and the stabilizers are PCB screw-in, the type enthusiasts prefer because they rattle less than plate-mounted stabs. The kit includes sound-absorbing foam and case foam.
Programming runs through QMK and VIA, so you can remap every key and create layers in a browser-based tool without installing proprietary software. A knob version of the barebone is also sold for those who want a rotary control.
Strengths: premium CNC aluminum case; double-gasket mount with screw-in stabilizers; 3-pin and 5-pin hot-swap; open QMK/VIA programming.
Drawbacks: wired only with no battery; no function row; heavy, so it is not a travel board; costs more than the budget kits above.
How it compares: it costs more than the GTSP M87 and GMMK 60% but brings a full aluminum case and better stabilizers. Choose it over the GMMK 60% if you want arrow keys and a premium feel; choose the BOYI GMK67 below if wireless matters more than a metal case.
10. Keychron Q6 Max Barebone (Full Size, Wireless)
The Q6 Max is the premium answer for builders who want a full-size board with a number pad and wireless freedom. Where the ZMX GMK104 kits offer full size and tri-mode wireless in a plastic case, the Q6 Max wraps the same idea in a full CNC aluminum body with a double-gasket mount, a polycarbonate plate and layered IXPE, PET and latex foams aimed at a deeper, quieter sound.
Connectivity includes 2.4GHz wireless at a 1000Hz polling rate, Bluetooth for up to three devices, and USB-C wired. Keychron rates the 4000mAh battery at up to about 180 hours with backlighting off. The barebone version comes with a knob that controls volume by default and can be remapped through QMK/VIA. RGB is south-facing, stabilizers are screw-in, and NKRO works both wired and wireless.
Strengths: full-size layout with number pad; premium aluminum case; tri-mode wireless with long battery life; programmable knob; QMK/VIA.
Drawbacks: very heavy (over 2kg fully built); occupies a lot of desk space; one of the most expensive kits in this guide; Bluetooth polling is lower than 2.4GHz, so use the dongle for gaming.
How it compares: it costs well over twice as much as the ZMX GMK104 but replaces plastic with aluminum and a more refined mount. Choose it if you type all day on a full-size board and want a keyboard you will keep for years.
11. Glorious GMMK 3 Pro Barebones (75%)
The GMMK 3 Pro is Glorious’ current flagship barebones kit and the natural upgrade path from the GMMK 60% and GMMK 85% kits listed earlier, which are older designs. It uses a 75% layout with a function row, arrow keys and a programmable knob in a CNC aluminum case.
Its standout feature is a modular gasket system: you can swap gasket pieces to make the typing feel softer or firmer, which is unusual at this level and useful for builders still discovering what they like. An aluminum plate and two layers of dense foam aim for a neutral, damped sound. The hot-swap sockets accept 3-pin and 5-pin mechanical switches. Lighting covers three zones (per-key backlighting, side lights and a badge), and the board is configured through Glorious CORE software, with up to 1000Hz polling on this wired MX version. The box includes a braided cable, sample switches, spare screws and O-rings, switch and keycap pullers and a screwdriver.
Strengths: adjustable modular gasket system; aluminum case; knob with media controls; generous accessory bundle; two-year warranty.
Drawbacks: wired only in this barebones version; relies on Glorious CORE rather than open QMK/VIA; priced in the premium tier; some retailer listings mix up its specs with the separate Hall Effect version.
How it compares: it is far more refined than the LEOBOG Hi75C Pro in the same 75% size, and than the tenkeyless GTSP M87, at a significantly higher price. Note that the separate GMMK 3 Pro HE model, with magnetic switches and 8,000Hz polling, is a different product.
12. BOYI GMK67 Barebones Kit (65%, Tri-Mode)
The BOYI GMK67 has become one of the most recommended budget kits for first-time builders because it combines features that used to be premium-only: tri-mode wireless (Bluetooth 5.0, 2.4GHz and USB-C wired), a gasket mount, south-facing RGB and a multimedia knob, all at a price close to the wired-only GTSP M87.
The 65% layout keeps the arrow keys and a compact navigation column while dropping the function row and number pad. Gasket strips on the plate, PORON gasket material and internal foam reduce vibration and hollowness, and the hot-swap sockets accept standard mechanical switches without soldering (optical and magnetic switches are not supported). The board is programmable through VIA, so remaps and layers can be set without proprietary software. Most listings quote a 4000mAh battery, though figures vary between versions, so check the specific listing. A newer GMK67 Pro variant adds QMK/VIA firmware.
Strengths: tri-mode wireless at a budget price; gasket mount with good damping; knob; VIA programming; south-facing RGB.
Drawbacks: plastic case in the base version; no function row; battery specs differ between listings; quality control can vary more than with established brands.
How it compares: it costs a little more than the GTSP M87 but adds wireless and a knob. Choose it over the Keychron Q2 if wireless and value matter more than an aluminum case.
13. ZMX GMK81 Barebones with Screen (75%, Tri-Mode)
The ZMX GMK81 brings the screen-and-knob concept of the ZMX GMK87 and GMK104 kits above to a more compact 75% layout. It keeps the function row and arrow keys in a footprint smaller than a tenkeyless board, which suits gamers who want more mouse room without giving up dedicated F-keys.
The small TFT-LCD screen can display custom GIF animations, connection mode, time and battery status, and a knob handles volume. Connectivity is tri-mode (Bluetooth, 2.4GHz and USB-C wired), with a roughly 3000mAh battery. It is gasket-mounted with layered foams in a polycarbonate case, uses south-facing RGB, and its hot-swap sockets accept 3-pin and 5-pin switches. VIA support covers remapping and layers. The same kit is also sold under other names, including FKZ and Zuoya.
Strengths: 75% layout with function row; screen and knob; tri-mode wireless; 3-pin and 5-pin hot-swap; VIA.
Drawbacks: plastic case; smaller battery than the GMK67 and Q6 Max; the screen is more novelty than necessity for many users; Bluetooth polling is lower than 2.4GHz.
How it compares: it is the compact sibling of the GMK87 and a wireless, screen-equipped alternative to the GTSP M87. Choose it if you like the ZMX screen concept but want a smaller board than the GMK87 or GMK104.
14. LEOBOG Hi75C Wired Aluminum Kit (75%)
The wired Hi75C is the budget-aluminum option in this guide and the simpler sibling of the LEOBOG Hi75C Pro listed above. It became popular because it puts an aluminum case under a gasket-mounted 75% layout at a price close to many plastic kits. If you like the Hi75C Pro but do not need wireless, this version saves money and drops the battery weight.
LEOBOG lists an 81-key 75% layout with a multifunction knob, an aluminum case, a 1.2mm hot-swap PCB with flex cuts, a flex-cut plate, factory-lubed plate-mount stabilizers, south-facing RGB and full NKRO. The sockets accept 3-pin and 5-pin switches, and the gasket structure uses PORON gaskets with layers of sound-dampening foam. Connection is USB-C wired only, and the fully built board weighs about 1.2kg, heavy enough to stay put during gaming.
Strengths: aluminum case at a budget-friendly tier; gasket mount with flex-cut PCB and plate for a softer feel; knob; 3-pin and 5-pin hot-swap; south-facing RGB.
Drawbacks: wired only; plate-mount stabilizers are less tunable than the screw-in stabilizers on the Keychron kits; plate material can vary between batches and retailers, so check the listing.
How it compares: it lands in a similar price tier to the Keychron Q2 while adding a function row and a knob in a 75% layout, though the Keychron has better stabilizers and open QMK/VIA support. Against the GTSP M87, it trades a slightly higher price for an aluminum case.
Buying Guide
Mounting, Layout, and Typing Feel
Gasket mounting is the defining comfort feature in this category. Good implementations feel evenly cushioned with muted bottom-out, while poor ones feel inconsistent or overly bouncy. Layout determines daily convenience: compact 60 percent saves space but relies on layers, 75 percent keeps arrows and function keys in a small footprint, and TKL or full size restores dedicated controls at the cost of desk space.
Hot-Swap Sockets and Lighting Position
Look for hot-swap sockets that accept both common pin configurations and hold switches securely without bending pins. Tight, well-aligned sockets prevent wobble and make future switch swaps painless. South-facing RGB is preferable for compatibility, as it reduces interference with taller keycaps and delivers more even shine-through for most aftermarket sets.
Connectivity and Programmability
Decide early whether you need wireless. Wired USB-C is simple and reliable, while triple-mode options add Bluetooth and 2.4 GHz for flexible placement across devices. Programmability matters just as much: VIA support and onboard controls like a knob or screen let you remap layers, create macros, and adjust lighting without juggling extra software, which pays off every day after the build is done.
What Else You Need to Finish a Barebones Build
A barebones kit is only part of a working keyboard. Budget for these before you order:
- Switches: one per key plus a few spares. A 65% board needs about 67 to 68, a 75% about 80 to 84, a TKL 87, and a full-size board 104 or more. Switches are commonly sold in packs of 35, 70, 90 or 110.
- Keycaps: make sure the set covers your layout. 65% and 75% boards often have a shorter right Shift or unusual bottom row, so look for sets that list compatibility with compact layouts.
- Tools: a switch puller and keycap puller (many kits include them), and optionally a small screwdriver for opening the case to tune stabilizers.
- Optional tuning supplies: stabilizer lubricant, extra foam or tape mod materials if you want to adjust the sound later.
As a rough rule, switches and keycaps together can cost as much as a budget kit itself, so a “cheap” barebones board is not always cheaper than a prebuilt keyboard. The value is in choosing exactly the feel and look you want.
3-Pin vs 5-Pin Switches and Why It Matters
MX-style switches come with either three pins (two metal contacts and a center plastic post) or five pins (two extra plastic posts for stability). Most modern hot-swap kits, including the Keychron Q2, GMMK 3 Pro and ZMX GMK81, accept both. Some older or budget PCBs only have holes for three pins; in that case, five-pin switches will not seat unless you clip the two extra legs with flush cutters. Check the kit’s listing for “3/5-pin” support before buying switches. Also note that optical and magnetic (Hall effect) switches are a separate standard and will not work in a regular mechanical hot-swap socket.
Plastic vs Aluminum Cases
Plastic and polycarbonate cases, used by the GTSP, BOYI and ZMX kits, are light, inexpensive and often produce a softer, deeper sound, especially with good internal foam. Aluminum cases, used by the Keychron Q-series and GMMK 3 Pro, are heavy, rigid and stay put on the desk, with a more premium feel. Aluminum can sound pingy without proper dampening, which is why premium kits invest in gaskets, silicone pads and multiple foam layers. If you move your keyboard around or want wireless use on the couch, plastic is more practical; if the board stays on one desk, aluminum is the more satisfying long-term choice.

Step-by-Step: Building Your First Barebones Kit
- Test the PCB first. Before installing anything, plug the board in and use a key tester website, shorting each socket gently with tweezers or testing a single switch, to confirm every position registers.
- Check switch pins. Make sure every pin is straight before pressing a switch in. Bent pins are the most common cause of dead keys.
- Install switches with support. Press each switch in straight, ideally holding the plate from below near the socket so the PCB does not flex. Start with the corners to keep the plate aligned.
- Test again. Run the key tester once all switches are seated to catch any that need reseating.
- Fit keycaps. Install stabilized keys (Space, Shift, Enter, Backspace) carefully so the stabilizer stems seat evenly.
- Program the layout. Open VIA, QMK or the manufacturer’s software to set layers, the knob function and lighting.
- Tune over time. If you hear rattle on large keys, lubricating the stabilizers usually helps more than any other single change.
Which Kit Fits Which Builder?
- First build on a tight budget: start with the GTSP M87 or the BOYI GMK67. Both are inexpensive, gasket-mounted and hot-swappable, so mistakes cost little and you can experiment with switches.
- Competitive gamers: a compact layout frees mouse space. The GMMK 60% is the smallest, while 75% boards like the GMMK 3 Pro, LEOBOG Hi75C and ZMX GMK81 keep a function row for game binds. Use a wired connection or a 2.4GHz dongle for play.
- Typists and office use: full-size or TKL boards with a comfortable gasket feel suit long writing sessions. The Keychron Q6 Max and ZMX GMK104 keep the number pad; the GMMK 85% TKL drops it.
- Premium feel without a premium learning curve: the Keychron Q2 and GMMK 3 Pro bring aluminum cases, good stabilizers and polished software in kits that are straightforward to assemble.
- Clean, cable-free desks: tri-mode kits such as the BOYI GMK67, ZMX GMK87 and GMK81, LEOBOG Hi75C Pro and Keychron Q6 Max let you switch between a PC, laptop and tablet over Bluetooth.
Whatever you choose, remember that the switches and keycaps you add shape the final experience as much as the kit. A mid-range kit with well-chosen switches and lubed stabilizers will often feel better than an expensive kit built carelessly.
Our Verdict
For most builders, the GTSP M87 Kit in Black is the top pick because it nails the essentials — comfortable gasket feel, broad hot-swap support, and a practical tenkeyless layout — at a very accessible price. The budget pick is the GLORIOUS GMMK 60% Compact Barebone, which offers a very low entry cost for a clean, space-saving custom base. If you need full size coverage with a screen, knob, and flexible wireless plus VIA programmability, the ZMX GMK104 kits win despite their larger footprint.
FAQ
What does barebones mean for these kits?
Barebones means you get the case, PCB, plate, and stabilizers without switches or keycaps. You supply your preferred switches and keycap set to set the feel, sound, and look. It lowers cost and lets you personalize the final typing experience.
Are hot-swappable kits good for beginners?
Yes, they are ideal for beginners because you can install and swap switches without soldering. You can try different switch types to find your preference and replace a faulty switch in seconds. Just align pins carefully and avoid forcing switches.
Do I need south-facing RGB?
South-facing LEDs work more cleanly with most modern keycaps and reduce harsh glare. They help avoid interference where north-facing sockets can catch on keycap housings. If you use taller or opaque keycaps, south-facing lighting usually provides more even illumination.
Should I choose wireless or wired?
Choose wired if you want the simplest, most reliable connection for gaming and do not mind a cable. Choose wireless if you value a clean desk and easy switching between devices, and you want the option to use the board away from the cable. Wireless kits with VIA and knobs add convenience for media and layer control.
How many switches do I need for my kit?
Count the keys on the layout and add a few spares. A 65% board typically needs about 67 to 68 switches, a 75% around 80 to 84, a TKL 87 and a full-size board 104 or more. Packs of 70 or 90 cover most compact builds with spares left over.
Can I use Hall effect or optical switches in these kits?
No, unless the kit is specifically designed for them. Standard hot-swap kits use mechanical MX-style sockets. Magnetic switches require a Hall effect board such as the separate GMMK 3 Pro HE, and optical switches require an optical PCB.
Is QMK/VIA better than manufacturer software?
QMK and VIA are open and work across operating systems, often through a web browser, and your keymap is saved on the keyboard. Manufacturer software like Glorious CORE can offer more polished lighting controls but ties customization to one brand’s app. For most builders, VIA support is a strong plus.
Does a wireless barebones kit have input lag for gaming?
Over a 2.4GHz dongle, kits like the Keychron Q6 Max run at up to 1000Hz polling, which is suitable for gaming; budget tri-mode kits generally also recommend the dongle for play. Bluetooth is typically much lower, around 90Hz on some boards, so use Bluetooth for typing and switching between devices, and the dongle or cable for games.
