What parts have you purchased but regretted buying later? I know we all think our purchases are right at the time, but what parts have you purchased that you feel were overkill, underwhelming or just the wrong part for the job? I have a few, here are mine.
Phanteks Enthoo Luxe, don't get me wrong it's a phenomenal case but the window on the side makes me care waaaay too much about aesthetics. Also, it was expensive as balls and it's huge. If I could do over, I'd go with something more quiet and something more minimalist, like the Define R4/R5 or Define S. Corsair H100i, it's loud as fuck and I haven't even overclocked any chips with it yet. The cooler I was running before (Arctic Freezr 7 Pro) didn't look great, but temperatures were similar. 1000W PSU, I had plans to crossfire two 290x at the time, but due to the 900-series launch I changed my mind. This is way too much, hell even a 500W PSU could power my system.
