Last time I spent like 4 hours just to swap a graphics card. Granted 3.5 of those hours was me accidentally snapping off the shitty plastic spring things that were holding the heat sink that was right next to the graphics card on and then having to dig through all my spare screws and parts and shit to fashion a replacement means of holding that heat sink back on and then removing the motherboard to actually install them and reinstalling that. That was a fun sunday evening.
