Seems like quite a few people built PCs because Apple's desktops have been atrophied, that definitely played a part for me, too :) I've designed a water cooled mITX system with PCIe GPU that should've fitted into a 2DIN car radio slot, which is doable with a deep enough slot, a PCIe riser, and even a DC/DC power supply in the box. I never got around to actually building that due to life getting in the way, but the components ended up in a laser-cut acrylic cube crammed as small as can be. I have to say the laser-cut acrylic case works quite well, and is well within reach of anyone with a maker space close-by and basic CAD skills. TL;DR: anecdote about SFF PC building.
