Your first custom mechanical keyboard
No soldering. A hot-swap kit, switches and keycaps you chose, and the three tools worth owning.
A first 'custom' build in 2026 is not soldering. It is a hot-swap barebones kit plus switches and keycaps you picked, optionally lubed. For $200–350 you get a board that sounds and feels exactly how you want, and you learn enough to know what to upgrade next.
Pick the size first: 75% keeps F-keys and arrows in a compact footprint and is the safe choice for developers; 65% if you never touch F-keys. Then pick a switch family with a tester in hand: linear (smooth, Oil King), tactile (bump, Akko V3 Pro) or clacky linear (HMX). Keycaps are taste; thick PBT in Cherry profile is the comfortable default.
Remapping is done in VIA in the browser (Keychron boards) or QMK for anything deeper. Map Caps Lock to Escape/Control and thank yourself later.
The kit
Aluminum gasket-mount Q1 Max, Oil Kings, Akko caps, a lube kit and a mat. The build most people stop at.

- 01 · Board$$$
Keychron Q1 Max barebone (75%, knob, QMK/VIA)
The consensus first custom kit: CNC aluminum, gasket mount, hot-swap, wireless.
Full aluminum case, gasket mount, a 5-pin hot-swap PCB, QMK/VIA remapping, 2.4 GHz plus Bluetooth plus wired, with screw-in stabilizers and acoustic foams pre-installed. It sounds good stock, which matters when you do not yet know what you like. The Q2 Max is the same board in 65% without the F-row.

Gateron Oil King linear switches (90 pack)
The best-selling switch of 2024–25: factory lubed, deep, usable stock.
Smooth and 'thocky' out of the bag with minimal wobble, which is exactly what you want when you have not learned to lube yet. 55 g bottom-out suits typing and gaming. Buy 90 for a 75% board (84 needed, spares matter).

Akko 9009 Retro Cherry-profile PBT keycap set
Thick double-shot PBT, Cherry profile, 150+ keys so 65/75% layouts are covered.
Akko's sets give you GMK-style looks at a third of the price with Mac-compatible keys included. Cherry profile is lower and more comfortable than OEM for long typing sessions. The Neon, Warm Gray and Mochi & Dango sets are the same quality in other colors.

Switch tester (9–20 switches)
$18 here saves $60 on the wrong 90 switches.
Pick a tester that includes an Oil King, an Akko tactile and an HMX linear so you compare the three families that matter in 2026. Your opinion after two minutes of pressing is worth more than any review.
Buy this first, a week before the rest.

Keyboard lube kit (switch opener, brush, station, pullers)
The $20 bundle of tools you need once, forever.
Switch opener, a size-00 brush, a lube station, tweezers, and switch and keycap pullers. The Q1 Max ships with pullers and a hex key, so you only need this if you plan to lube or swap switch springs.
Find on Amazonpaid link - 06 · Lubeoptional$
Krytox GPL 205g0 lubricant (5 ml)
The universal switch and stabilizer grease. A vial does 300+ switches.
Thin, glossy, no visible white: that is the whole technique. 205g0 is the one lube that works on linears, stabilizer housings and wires. Add Krytox 105 oil later if you start bag-lubing springs. Lubing is optional on a first build with factory-lubed switches.

Desk mat, 900×400 mm, stitched edge
Deadens case ping and makes any board sound deeper.
A 4 mm mat under an aluminum case removes the hollow desk resonance that makes good boards sound cheap. Any stitched-edge mat works; Keychron, Deltahub and Grovemade are the usual picks.

Skip this / common mistakes
- !
Don't assume your kit takes 5-pin switches. Keychron Q and V boards do; some budget kits are 3-pin only. Check the listing.
- !
Don't buy 61 switches for a 75% board. You need about 84; buy 90.
- !
Don't lube on your first build unless you want to. Oil Kings and Akko V3 Pros are good stock, and lubing 90 switches takes 2–3 hours.
- !
Don't over-lube. The number-one beginner result is a mushy, inconsistent board.
- !
Don't buy a Keychron HE (Hall-effect) board for a first mechanical build: you cannot swap in MX switches.
Questions people ask
Do I need to lube switches?
No. Factory-lubed switches like Gateron Oil King, Akko V3 Pro and HMX are 80% of the way there. Lube the stabilizers if the spacebar rattles; that is the one mod with a big payoff.
What size should my first keyboard be?
75% keeps F-keys and arrows in a compact footprint and is the safest for developers. 65% if you never use F-keys and want more mouse room.
Linear or tactile?
Linear for a smooth typing feel and gaming; tactile if you want feedback without clicky noise. A $18 switch tester answers this better than any review.
Keychron Q1 Max vs Q1 Pro vs Q1 HE?
Max adds a 2.4 GHz dongle and better foams. Pro is the cheaper Bluetooth-only previous generation and a good deal when discounted. HE uses magnetic switches for gaming and is not hot-swap compatible with MX switches.

Pairs well with
Ergonomic developer desk
Monitor at eye height, a chair that fits, a desk that lets you stand. Buy those first; cheap out on the rest until it bugs you.
Raspberry Pi & electronics bench
A Pi 5 that doesn't throttle or brown out, a Pico for the bare-metal stuff, and the iron and meter that outlast every project.
E-ink reading & analog notes
The one gadget that makes you do less, plus the notebook and pen you'll actually open.
