What to confirm
- MX stems, standard height
- 65%/68-key kit coverage: 1.75u right Shift, 1u right column
- Shine-through if you want the M68's bright RGB to show; the budget stock caps are shine-through ABS
Upgrade logic
Womier boards are bought for RGB looks at low prices; the caps are the weakest part. A double-shot PBT upgrade fixes texture and durability, though opaque PBT will mute the light show. Pudding-style caps are the middle path: PBT walls with translucent sides that amplify RGB.
Switch note while you are in there
Hot-swap M68 versions take any 3/5-pin MX switch, so cap and switch upgrades usually happen together. Nothing on this board is proprietary; it is a standard canvas.
Cherry profile caps: the one thing to check
Budget RGB boards often mount switches north-facing to put the LED under the legend, and switch orientation on the M68 has varied by run, so check your unit before buying a strict Cherry-profile set. On a north-facing plate, Cherry-profile caps can touch the switch housing on certain switches before full bottom-out, producing a subtle interference tick. OEM, XDA, DSA, SA and the stock profile all clear without issue, and plenty of switch and Cherry-cap pairings are fine too. If you have your heart set on a Cherry-profile set, test one cap on one switch before committing to the full board, or pick switches the community has already confirmed clear on north-facing plates. This is a nuisance, not a dealbreaker, but it is the one fitment wrinkle this otherwise standard board has.
How the stock caps age, and what replaces them well
Owners report the stock shine-through ABS doing what thin ABS always does: legends stay crisp, but the surfaces polish to a shine on the home row within months of heavy use. That is cosmetic, not functional, and it is the usual trigger for an upgrade. Double-shot PBT resists shine for years and adds a drier, deeper sound on this board's light case; dye-sub PBT does the same but blocks the backlight entirely. If you type mostly by feel, opaque PBT is the durable endgame. If the light show is the point, pudding or shine-through double-shot caps split the difference and hold up far better than the originals.
Caps first or switches first
On a budget board where both upgrades tempt you, the community's usual order is caps first. Keycaps change what your fingers touch a thousand times an hour and fix the M68's weakest stock component, while the stock switches are serviceable. Switches change sound and press feel more, but cost more to do well across sixty-eight keys. The exception: if your unit came with switches you actively dislike, scratchy or too light, swap those first, since no keycap fixes a bad switch. Doing both together also works; the board comes apart once, and the transformation is bigger than the sum of the parts.
