Well which Area 51 case are you talking about? Is it the Area 51 ALX desktop Case? Or the Area 51 R2 through the R7 Series Desktop? Also, I know that these cases support standard atx motherboards. While the case is proprietary, you can work around that and install aftermarket components inside the case.

All of the aluminum panel parts are glued/epoxied to the ABS-type plastic backers, 'permanently'. I'd say they can not be removed/separated & then reapplied/glued/expoxied afterwards, the metal would warp or dent or wrinkle or otherwise incur damage in the attempt of prying apart. While plenty of people have done paint jobs successfully by carefully masking-off areas (ie chrome strips etc) You'll ruin the top panel before u get it separated from its backer (I assume u want to 'push' the dings back & otherwise flatten them starting from behind, but u really can't), so for the panel dings I'm forced to suggest 'Bondo' then sand then prime then paint, or try to find a new panel & paint it. Try to chat @ Dell Spare Parts for part# R841R lunar shadow front panel / bezel, or try google/eBay Tip: take great care of the ribbon cable when putting the bottom panel back on / back together (per photo #1) Any thoughts on what color change you're after? For PSU, just slide in an aftermarket type when you're ready for one, it will have fan clearance no problem, just needs a 120/140mm dust filter (or screen-mesh) to catch/protect from falling sc rews etc, see my page  I can't visualize what your vents are doing, lol, generally, launch CmndCntr & uncheck the box > 'flare on startup' … other times, vents & start-up 'behavior' can change based on which W10 build/version you're on now or were on or will be on in the future, for better or worse For vents on W10, try here?
