It's still missing wi-fi, bluetooth, sc dongle, sd card reader, (frugal) led bar, the hdmi cec functionality and whatever you value yourself for assembly, installation, troubleshooting and tweaking time (between half an afternoon to a whole day). Dealing with pc bioses is tedious and tweaking fan behavior and thermals could take a whole other day, which you are gonna need because the cheapo case you've picked up only comes with a single loud fan and poor ventilation for pc case standards, so you either gonna have a loud motherfucker or a cooked to perfection unreliable rig.
Let alone having to put the PC on the floor because it won't fit anywhere else in the living room.
