I wouldn’t call them guilty secrets, but I do get where you are coming from with this post. I’ll bite & show 3 of my boards that could fall under this description. First off my ALPS64 build,
It’s got SKCM orange switches, the plate is cutout from an original AEKII plate, the case is a KBDfans Lambo clone, & the caps are just regular AEKII caps. Nothing special to look at, but boy does she type! In fact this has quickly become my go to board for any extended typing sessions & my DD for the most part (except gaming).
The second board I would put in here is my Leopold FC660M,
I swapped out the Cherry blacks it originally came with for spring swapped & lubed MOD Ls (swapped to 80g gold plated springs & lubed with my personal Krytox thick mix). Then I put a set of ePBT orange & black Cyrillic caps with some artisans on it to spice up it’s looks. I plan on eventually finding a aluminium case for it, but as it stands it’s still in it’s original plastic case. This one has a little more pop to it visually thanks to the caps & artisans, but could be easily mistaken for an off the shelf 660M just by looks. Thanks to the switch swap though it is a joy to type on & my go to gaming board.
Then for the third board I’ll show you my Let’s Split,
It’s got spring swapped & lubed Cherry clears (same springs & lube as the MOD Ls in my 660M), a cheap acrylic sandwich case, & some cheap PBT DSA caps from KBDfans. Again nothing really special to look at, but it has a great feel to it. The acrylic case & rubber feet I used with it makes for a really soft typing experience that is pretty unique IMO.
