The Board: Your first keyboard built from parts, not a box — Build Guide

Your first keyboard built from parts, not a box, is a barebones hot-swap kit — a case and PCB with sockets, switches you press in by hand, and keycaps you picked for more than just the legends. The whole assembly takes twenty minutes once the parts arrive, and you'll understand why people start talking about keyfeel instead of just typing.

Key points

• A hot-swap barebones kit like the GMK87 Keyboard Barebones Kit requires no soldering — switches press into sockets by hand.
• Gateron Milky Yellow Switches are linear and quiet; Gateron G Pro 3.0 Blue Switches are tactile and clicky, and the choice determines how the board feels and sounds.
• Keycap sets such as XVX MOA Profile Japanese Fuji Mountain Theme PBT Keycaps Set or XVX Matcha Wagashi PBT Keycaps replace the stock legends and change the board's appearance entirely.
• The build involves fitting stabilisers, pressing in switches, snapping on keycaps, and plugging in the board — total assembly time is under half an hour.
• The kit arrives with stabilisers, a case, a hot-swap PCB and a cable; you supply the switches and keycaps separately.
• This is a gateway build — once it works, you'll start noticing switch weights, keycap profiles and the sound signature of different case materials.

What you are building and why it is worth one evening

A barebones hot-swap kit is a keyboard case and PCB sold without switches or keycaps. The PCB has sockets instead of solder pads, so switches press in by hand and pull back out just as easily. You buy the switches separately, choose keycaps that aren't blank beige rectangles, and assemble the whole thing in the time it takes to watch a film.

This is the gateway build of the keyboard hobby. No soldering iron, no firmware flashing unless you want to, and no commitment beyond the switches you bought. If you hate the clicky blues, pull them out and press in linears. The board still works.

You'll finish the build and then spend three days telling people about switch actuation force.

The parts list: what each item in the kit cart does

The GMK87 Keyboard Barebones Kit is a tenkeyless board — full-size keys, no numpad. It arrives with the case, the PCB, the stabilisers for the wider keys, and a USB cable. The switches and keycaps are separate purchases.

Switches determine how the board feels and sounds. Gateron Milky Yellow Switches are linear — a smooth press with no bump or click, quieter than most. Gateron G Pro 3.0 Blue Switches are clicky — a tactile bump and an audible click on every keypress. Linears are for open-plan houses; clickies are for spite.

Keycaps are PBT plastic moulded into a profile. The XVX MOA Profile Japanese Fuji Mountain Theme PBT Keycaps Set has Japanese sublegends and a blue-and-white gradient. The XVX Matcha Wagashi PBT Keycaps are green, cream and pink. Both are thicker than the keycaps that ship with a prebuilt board, and the legends won't wear off in six months.

What you supply yourself, honestly

Twenty minutes, a keycap puller if the kit doesn't include one, and the willingness to become insufferable about switches. That's it.

You don't need a soldering iron. You don't need a screwdriver unless the kit ships with screws already fitted and you want to open the case. The switches press into the PCB sockets by hand — firm pressure, straight down, until they click.

The keycap puller is a wire tool that hooks under a keycap and lifts it off the switch without scratching the plastic. Some kits include one; most don't. If yours doesn't, they're cheap and you'll use it every time you want to swap keycaps or clean under the keys.

You'll also need the ability to look at a switch and a keycap set and not buy four more of each. That one's harder.

The build, in numbered phases sized to an evening each

This isn't an evening. It's twenty minutes. But it's the kind of twenty minutes where you sit down to fit the stabilisers and then look up and it's been two hours and you've ordered three more keycap sets.

Phase one: Stabilisers and the PCB

Open the kit. The stabilisers are the wider plastic assemblies that keep long keys like the spacebar from tilting when you press one end. The barebones kit includes them — usually pre-assembled, sometimes not.

If they're separate, snap the wire into the plastic housings. Then clip or screw the stabilisers into the PCB at the positions marked for the spacebar, shift keys, enter and backspace. The kit instructions will show which holes.

Test them. Press down on each stabiliser. It should move smoothly and spring back without rattling. If it rattles, the wire isn't seated properly or the housing isn't clipped in straight.

Phase two: Pressing in the switches

Take a switch. Look at the underside. Two metal pins and two plastic legs, arranged in a cross. The PCB has four holes per key, arranged to match.

Line up the pins with the holes. Press straight down until the switch clicks into the socket. Don't force it sideways — the pins are thin and they'll bend.

Start with the corners, then fill in the edges, then the middle. This keeps the plate aligned if the kit includes one. If a switch doesn't seat, pull it back out and check the pins — one of them is probably bent.

You need one switch per key. A tenkeyless board is eighty-seven keys, so buy ninety switches. The spares are for the bent pin you didn't notice until you'd already pressed it in.

Phase three: Keycaps

Keycaps snap onto the cross-shaped stem at the top of the switch. The legends tell you which keycap goes where — the letter, the symbol, the size.

Start with the alphas — the letter and number keys. Then the modifiers — shift, control, alt. Then the spacebar, which goes on the stabilised switch in the centre of the bottom row. Press each keycap straight down until it seats on the stem.

If a keycap doesn't fit, you've either got it on the wrong key or the stem isn't aligned with the switch. Pull it off with the keycap puller and try again.

Phase four: Plug it in

Connect the USB cable to the board and your machine. The board should register immediately — no drivers, no setup, just type. If it doesn't, unplug it, check that every switch is seated, and try again.

Open a text editor and press every key. You're looking for keys that don't register or register twice. A dead key means the switch isn't seated or the socket is faulty. A double-tap means the switch is chattering — pull it out and swap in a spare.

Where this build actually stalls, and how to get unstuck

It stalls at the bent pin. You press a switch in, it doesn't click, and when you pull it back out one of the metal pins is folded sideways. The pin is thin and easy to bend, and once it's bent it won't fit in the socket.

Hold the switch with the pins facing you. Use a fingernail or a plastic spudger to straighten the pin — gently, because metal fatigues. Press the switch back in. If it still won't seat, the pin is too damaged. Use a spare.

The other stall is the stabiliser rattle. The spacebar sounds like a maracas because the stabiliser wire is loose in the housing or the housing isn't clipped in properly. Pull off the spacebar keycap, unclip the stabiliser, check the wire is seated, and clip it back in. Test it by pressing the stabiliser directly, not through the keycap.

The last stall is keycap compatibility. You bought a keycap set that doesn't include the right sizes for your layout — usually the right shift or the bottom row modifiers. Check the kit diagram before you buy the keycaps. Most tenkeyless boards use standard sizes; some don't.

Safety, etiquette and the cleanup that keeps you allowed to do this again

This is a low-risk build. No soldering, no sharp edges, no mains voltage. The worst injury is a bent pin in your finger, and that's only if you're pressing switches while holding them loose instead of in the plate.

The etiquette is the sound. Clicky switches are loud. Gateron G Pro 3.0 Blue Switches click on every keypress, and if you're on a call, everyone hears it. Linears like Gateron Milky Yellow Switches are quieter — still audible, but not aggressive. If you share a house or take calls, buy linears first and clickies later when you've got the room to yourself.

Cleanup is minor. Keep the switch packaging for spares. Keep the keycap tray if the set came in one — you'll use it when you swap keycaps next month. Bent pins and plastic offcuts go in the bin. The work surface doesn't need covering; nothing in this build stains or scratches.

Ways to take it further once the base build works

Once the board works, you'll start noticing things. The stabilisers rattle. The case sounds hollow. The switches are too light or too heavy. This is normal. The next step is not buying another board — it's tuning the one you built.

Stabilisers can be lubricated with dielectric grease to reduce rattle. The case can be dampened with foam to reduce the hollow sound. The switches can be swapped — linears for tactiles, light for heavy, or just a different brand to see what changes.

Keycaps are the easiest swap and the most visible. Once you've built the board with one set, you'll start seeing keycap group buys and wondering if you need a second set in a different profile. You don't. But you'll buy it anyway.

The deeper step is firmware. Most hot-swap kits run QMK or VIA, which let you remap keys, program macros and adjust the lighting without recompiling code. You don't need it for the base build, but once you've lived with the board for a week, you'll want Caps Lock to be Control.

Common questions

Do I need to solder anything for a hot-swap build?

No. The PCB has sockets and the switches press in by hand. Soldering is for custom builds where you're fitting switches to a PCB without sockets. A hot-swap kit is the no-solder entry point.

How do I know which switches to buy — linear, tactile or clicky?

Linears are smooth with no bump. Tactiles have a bump you feel when the key registers. Clickies have a bump and an audible click. If you're not sure, start with linears — they're quieter and easier to live with if you're on calls.

Can I reuse switches if I want to try a different type?

Yes. Pull the keycaps off with the keycap puller, then pull the switches out of the sockets. Press in the new switches. The sockets are rated for hundreds of insertions, and switches don't wear out from being swapped.

What if a key doesn't register when I press it?

Pull the keycap off and check the switch is seated properly in the socket. If it is, try a different switch in that position. If the new switch works, the old switch is faulty. If the new switch doesn't work, the socket or PCB is faulty.

Do I need to configure the board or install drivers?

No. Plug it in and it works. The operating system recognises it as a standard keyboard. If you want to remap keys or program macros later, the board likely supports QMK or VIA, but that's optional.

Can I use any keycap set with any switch?

Almost always. Keycaps fit the cross-shaped stem on top of the switch, and that stem is standardised. The exception is if the keycap set doesn't include the sizes your layout needs — check the kit diagram and the keycap compatibility list before buying.

How long does the build take start to finish?

Twenty to thirty minutes for the assembly. Another ten to test every key. The time expands if you're lubricating stabilisers or tuning switches, but the base build is under half an hour.

What if I bend a switch pin while pressing it in?

Pull the switch back out. Use a fingernail or a plastic tool to straighten the pin gently. If the pin won't straighten or breaks, use a spare switch. This is why you buy a few extra.

Who this build is for, and who should wait

This build is for developers who want to understand why people talk about switches and keycaps instead of just buying the next mechanical board on sale. You'll spend twenty minutes assembling it and then three months swapping switches to see what changes.

It's not for someone who wants a board that works and then never thinks about it again. Prebuilts are faster and cheaper for that. This is for the person who reads setup posts and wonders what linear switches feel like, or who sees a keycap set and wants to know if it's worth it.

If you're happy with your current board and you're not curious about the components, don't build this. If you've been curious but didn't want to solder, this is the one.
