My case searches continue, I found this one which I really like:
Silverstone RL08. I really like Silverstone, and I like how this flips the motherboard so the video card is at the top (though I've been looking at vertical mounts too). Mesh front if I stick with air cooling, though I don't like the drive bay being there.
But needs a mATX board.. and I've got an i7-6700k which isn't the newer socket type on new motherboards. So I might stick to ATX, I don't really want to upgrade my whole system, though I didn't realize it's been what, 4 or 5 years since I upgraded last time?! Crazy.
Some AIO coolers put their pumps on the same PWM as the fans so the pumps can be slowed down, I like that idea to ensure the PC is near silent at idle.
