I use Windows 11 inside of a Gentoo vm inside of Windows 10 on my ipad.

I have the sparkle brand intel low profile single slot in an hp sff PC and it barely fits and leaves about 3/8" space between the power supply. It has all the room in the world in the backside. One slot over is a 1x pcie slot if only hp had switched the two or the video card had straight through and out of the case cooling.

I’m excited, but I wish gpu manufacturers would jump on board with physically compatible cards with ffs or smaller form factor business machines. HP, Dell, et al like to limit space for traditional GPUs in those machines. If there was a half height mid/low grade gpu with components on the reverse side that would be a great couch gaming machine.
