I'm pretty active on here, so you'll see me around, depending on the section. I'm a heretic. I think the aesthetics and build quality of the K65 and K70 are fantastic. I plan to modify at least 3-4 of them to my liking to replace the MX switches. I already have a K65 with box navies in it. The only major problem is the non-standard cap sizes, which I think is where most of the hate for them comes from. You like MX red over Topre? Interesting, considering all of the hype around Topre. I have no opinion myself, never tried Topre. I do think that linears are the strong point of the MX design though. I like Kailh's box reds more than the MX reds. Smoother, maybe even a touch heavier, which is good since MX reds seem just too light. I can rest my fingers on them and they might actuate.
What switches have you tried? I'm a clicky guy myself.
I think you're filling a niche that is pretty starved with that design in the custom/premium board arena, a relatively compact board that has a rotary encoder. I wish the K65 had a slider like the K70, and you typically don't see them at all on anything even as large as a TKL. There are things like the Satisfaction 75, which I want if they ever become obtainable, but choices are very slim. That explains your encoder's location. I was going to ask otherwise.
That's the thing though, I hope nobody becomes complacent. I see it here already. Numbers are down so everybody wants to open everything back up already. It doesn't make any sense, not until we're sure we've wiped it out entirely in our country, or have obtained a vaccine.
You could design some novel masks, or something. They say hepa filters and vacuum bags work almost as well as proper N95 masks. It would be nice to see something that incorporates a relatively common/universal filter or bag of the sort. I don't know about there, but there are a lot of people literally just buying up fabric and thread and pumping out a bunch of home-made masks to sell for a few bucks each.
