2. Case
The case houses everything. It's the largest single factor in how a keyboard sounds and feels — the material, weight, and mount style all dramatically affect the typing experience.
Mount Styles
- Tray mount: PCB screws directly to the case floor. Stiff, rigid, bright-sounding. The most common budget construction. Tape mod can soften the sound profile here.
- Top mount: Plate screws to the top case piece. Slightly more flex than tray, better sound isolation. More common in mid-range boards.
- Gasket mount: PCB/plate sandwich sits in silicone or foam gaskets. The mount style absorbs keystroke impact, producing flex and a deep sound. The enthusiast standard for mid-to-high end boards. Found in Keychron Q series, KBDfans Tofu84, Portico, Satisfaction75.
- Top mount with isolated top: Hybrid designs like the Bakeneko where the top piece floats. Community increasingly creative about mount designs.
Materials
- Aluminum (6061 or 7075): Dense, premium, deep sound. 7075 is stiffer than 6061. Weight ranges from 600g (budget 65%) to 1.5kg+ (slab aluminum endgame). KBDfans, Gmmk Pro, and Keychron Q use aluminum.
- Polycarbonate: Transparent/translucent, flexible, lighter. Pairs with gasket mount for maximum flex. More "bouncy" under fingers than aluminum. Good for underglow RGB builds.
- Acrylic: Budget PC alternative. More brittle, prone to cracking. Often used for acrylic "sandwich" builds — function over form.
- Plastic (ABS/nylon): Budget entry point. Higher-pitched sound, lighter. The Keychron V series uses a plastic body — excellent value despite material.
3. PCB (Printed Circuit Board)
The PCB is the brain of the keyboard — it registers keypresses and sends signals to the computer via USB or Bluetooth. Key decisions:
Hotswap vs. Solder
- Hotswap PCB: Pre-installed Kailh or Millmax sockets. Push switches in, pull them out with a switch puller. No soldering required. Can swap to different switches in under 10 minutes. Beginners should start here. Downside: socket wear over 50–100 swaps; bent pins can damage sockets.
- Solder PCB: Switches are soldered to the PCB permanently (until desoldered). More PCB options available. More stable mounting. Necessary for some exotic configurations and custom matrices. Mistakes require a desoldering pump and patience.
Connectivity
- Wired USB-C: Standard. Zero latency. Always reliable.
- Wireless (BLE): Some PCBs support Bluetooth + 2.4GHz wireless. Requires battery. Popular for clean desk setups.
Firmware
Confirm QMK support before buying any enthusiast PCB. VIA compatibility means real-time remapping without flashing. ZMK is an alternative for wireless builds. Most PCBs ship with QMK pre-flashed.
DZ65RGB (65% hotswap), BM60 (60% hotswap), KBD67 Lite (65% gasket hotswap). All run QMK, all VIA-compatible. The KBD67 Lite is the community's current beginner recommendation for 65% builds.
4. Plate
The plate sits between the PCB and switches, aligning switch positions and influencing sound. Plate material is a major sound-shaping variable:
| Material | Stiffness | Sound | Weight | Cost |
|---|---|---|---|---|
| Aluminum | Very stiff | Bright, clacky | Heavy | Low–Mid |
| Brass | Very stiff | Deep, thocky | Very heavy | Mid |
| Polycarbonate (PC) | Flexible | Deep, muted | Light | Low–Mid |
| FR4 (Fiberglass) | Slightly flexible | Neutral | Light | Low |
| Carbon Fiber | Very stiff | Crisp, unique | Very light | High |
| POM (Polyoxymethylene) | Slightly flexible | Warm, muted | Mid | Mid |
Beginner recommendation: Start with whatever plate comes with your case kit. Then experiment — most mid-range boards sell alternative plate materials separately. A brass plate swap on a budget board is one of the best-value upgrades in the hobby.
5. Switches + Quantity Calculator
Always order 5–10% extra switches. On hotswap boards you'll inevitably bent a few pins. On solder boards, one bridge can kill a switch. Having spares means no project delays.
See the full switch types guide and the KeebTracker switch database to compare options and check current pricing.
6. Keycaps
Keycap selection covers profile, material, and legend type. See the complete Keycap Profiles Guide for the full breakdown.
- Budget (PBT, Cherry profile): Akko, NuPhy, Epomaker — $35–$50. Good shine resistance, solid dye-sub legends, wide colorway selection.
- Mid-range (PBT, Cherry or KAT): ePBT, Drop MT3 — $60–$90. Higher manufacturing tolerance, better colorway execution.
- Endgame (ABS doubleshot, Cherry): GMK via group buy — $120–$200+. Sharp legends, premium colorways. 6–12 month wait from IC to shipping.
Before purchasing any keycap set, verify it includes keys for your specific layout. Many budget sets only cover standard sizes — if your board has a 1.75u right shift, a 7u spacebar, or ISO enter, confirm the kit has them before ordering.
7. Stabilizers
Stabilizers prevent large keys (spacebar, left shift, enter, backspace) from tilting when pressed off-center. They're the most under-appreciated component in most builds — and the most likely to ruin the experience if neglected.
Types
- Screw-in stabilizers: Screw through the PCB. Stable, minimal wobble. Always choose screw-in if your PCB supports them. Brands: Durock v2, Everglide Panda, TX, C3 Equalz.
- Clip-in (snap-in) stabilizers: Snap into PCB cutouts. Less stable, more prone to rattle. Acceptable on budget builds only. GMK stock stabs are clip-in.
- Plate-mount stabilizers: Mount to the plate rather than PCB. Used on older designs and some compact boards. Not preferred by the community.
How Many You Need (65% example)
- 1× 6.25u spacebar stabilizer (or 7u if your layout uses a 7u spacebar)
- 1× 2u left shift
- 1× 2u enter
- 1× 2u backspace
Most full stab sets include all of the above. Check if your specific layout uses additional 2u stabs on the number row.
The Holee Mod (Do This)
Punch a small circle from a band-aid and place it on the PCB under each stab mount point. This adds a tiny pad that eliminates bottom-out rattle. Takes 5 minutes. Eliminates one of the most common sources of noise in budget builds. Do it on every build, every time.
8. Lube
The community's go-to for linears. Thick grease. Produces buttery, smooth feel. Do NOT use on tactile legs.
Thinner than 205g0. 3203 is lighter (more bump preserved), 3204 heavier. Apply to rails + stem, never tactile legs.
Super Lube or any dielectric grease. Apply heavily to stab wire contact points. The primary rattle cure.
A 3ml jar of Krytox 205g0 is enough for 3–4 full keyboard builds. Buy once and you're set. Cost: $10–$15 from NovelKeys, KBDfans, or 1upkeyboards.
9. Foam Mods
Foam mods are entirely optional but deliver outsized results relative to their cost. Most premium kits include some foam; budget kits often skip it.
- Case foam: Fills the bottom cavity of the case. Kills hollow resonance. If your kit doesn't include it, cut craft foam or neoprene to fit. Cost: ~$3.
- PCB foam: Goes between PCB and case bottom. Adds body to the sound and reduces ping. Often included in higher-end kits.
- PE foam (Tempest mod): Thin layer between PCB and plate. Cut switch holes as you install. The most impactful mod — transforms budget builds. PE foam from a craft store: $2–$4.
- Switch pad / switch films: Thin films that fit between switch top and bottom housing. Reduces wobble and adds a subtle sound change. Optional for most builds, beneficial for high-tolerance builds.
10. Tools You'll Need
| Tool | Required? | Cost | Notes |
|---|---|---|---|
| Small Phillips screwdriver (#0) | ✅ Required | $5–$15 | For case screws. iFixit kit covers all sizes. |
| Switch puller (wire style) | ✅ For hotswap | $5–$8 | Metal wire style only — the plastic clip puller damages sockets. |
| Keycap puller (wire style) | Strongly recommended | $5–$8 | Ring-style keycap pullers scratch legends — use wire. |
| Paintbrush (#0 or #00) | ✅ For lubing | $3–$6 | Art brush from a craft store. Cheap and effective. |
| Lube station | Recommended | $12–$20 | Holds 12–16 switch housings open simultaneously. Huge time-saver. |
| Tweezers | Recommended | $5–$10 | For PCB testing (shorting switch sockets) and handling small parts. |
| Soldering iron | For solder PCBs only | $30–$80 | Hakko FX-888D or Pinecil if you're serious. Cheap irons cause frustration. |
| Desoldering pump / wick | For solder fixes | $8–$15 | Essential if soldering. Mistakes happen. |
| Band-aids | For holee mod | $0 (you have these) | Punch circles for stab holee mod. |

The budget-to-experience ratio is brutal in this hobby. A $120 build lubed with 205g0 and the PE foam mod will out-feel most $250 gaming peripherals. The endgame budget buys marginality, not magic. Start small, learn your preferences, then upgrade deliberately.
