Maybe just go with a shelf and an "open frame" concept with a motherboard tray and fascia to mount your fans? Guiding airflow may be a trick but I can't imagine shrouds would be too difficult.
edit: Come to think of it you could use any rack mount case as the base and leave the top off. Would...
Looks like it checks your boxes.
3 front panel 120mm fans, 3 mid plane 120's, 2 80mm rear fans. Compatible through eATX motherboards and ATX PSU.

Add a laptop power brick and just about any passive speakers and you're set.
I have a similar board wired into an order picker at work with a pair of paradigm bookshelves and it shocks...
Reseat any cables that may have been bumped? No doubt my experience is less than yours, but I've had trouble with ribbon cables that were bumped only slightly out of alignment that caused problems till I went back and tweaked how they sat. Particularly this one circled in red. The position looks...
Need to second the redragon stuff. I have a k552 red led, and I got an RGB version for my son. Both are clicky tactile switches, I can't complain for the $40 CAD I paid for each. They're definitely an economy product, but a fair step above membrane keyboards in the price range.
I don't have anything to add, I do want to say that this is fantastic work. This kind of innovation leads to breakthroughs and it's exciting to see it happening in this field at a grassroots level.
I know you've been at it a while, please keep going.
Seemed straight forward to me. I only went through the form once to see what it would spit out for something in line with what I'd use day to day. For $1000 I think your options are a little low end. I have a similar setup to what's suggested ((2600k, z68, 16g DDR3 1600, 1 tb ssd) $200 combo...
1 5.25" bays
2 3.5" bays
2 2.5" mounting points
5 120mm fan locations (2 front, 2 top, 1 rear, 1 side(solid side panel only)
4 front USB (2 usb 3, 2 usb 2)
I grabbed one for $40 a couple months ago. It's cheap in areas (thin metal)...
Yeah, it's perfectly stable, and nothing I do requires anything much more powerful. I don't have time for hours on end gaming any more and until ryzen dropped I had no itch to upgrade. I'll likely wait for zen 4 and scoop up a zen 3 setup at the clearance sale.
