Gonna be fun to find a set... I don't like these printed caps. And the white is grey now lol
~Really? Fun?
I would think it'd be a PITA to find a set to match.. 6x spacebar will be the hardest, there are quite a few sets with extra kits that you can fill up the bottom row with as long as you can find a matching 6x spacebar.
The Razer Blackwidow uses 6x, but I doubt you'd want to use the caps from that. Also some Cherry boards have 6x spacebars (1800, 11800, etc), but the stem spacing may not match. Good luck.
