Looks good, cable management hard with that kind of PSU. How did u strip case for painting? I tried to be perfectionist long ago but finally gave that up . Built super tower build some time back,was proud of it until i really looked at it afterwards,piece of crap lol. This build was my OCD taking over, wait until u see the final pictures lol.
Cable management with that type of PSU and a super cheap case with zero cable management features makes for a great challenge (That's the nice way of saying it sucks! lol) Because it was a cheap case the body itself was bare steel and the front face was plastic so no need to strip. For the sides and top I sanded with 150 grit sandpaper followed by 220 grit to remove the gloss from the paint. I didn't bother taking it down to bare metal as the paint I used had a pretty good binding agent. I'm looking forward to my next case, something that can both water cool and have some cable routing holes.
