I need to install a PSU KINGWIN|LAZER PLATINUM LZP-550 into a Fractal Define R4 case. This is my first PC build using a new case without a pre-installed PSU.
I'm not sure whether to install the PSU with the fan pointing up into the case or down towards the case bottom. There are holes punched in the case bottom, as if a fan should be drawing air up, so that's one vote. But I'm used to parking PCs on the floor, and having a fan so close to the floor, with all the dirt, dust, grime, and cooties seems, well, a bit dirty.
Addition: Shortly after posting I found an installation video that gave the news that the PSU can only be installed one way, owing to the positioning of punched holes and screws. My status as a Newcomer is confirmed
