How do I arrange my PSU in this case?

[Jim Bancroft]

I feel a bit silly asking, but better safe than sorry...I picked up this case at Newegg a bit ago:

I now have a 550W PSU for it:

...but I've only had ATX cases where the power supply sits at the top. On these bottom-slotted cases, which way is the PSU fan supposed to face? Up, toward the top of the case, or down toward the floor?

The photos in the newegg ad indicate the bottom but I wanted to make sure. Thanks!

The PSU is mounted at the bottom. The fan can face up or down (there is a fan filter at the bottom in case you're worried about dust being sucked in).

Great writeup there, thanks for it.

Traditional wisdom says mount it with the intake fan down, to draw cool air from the bottom of the case... as opposed to drawing warmer air from inside the case.

I would assume the obvious, but... good point!

it's a crap-shoot of personal preference and airflow. You can filter the intake of a PSU drawing air from the bottom. You must have the case lifted off the floor, as I do with braked double caster wheels. In this configuration, the PSU air and cooling is isolated from the case interior, but the external air as coolest.

In my own case, I had two priorities: pressurize the case, and try to keep dust out of the PSU. I chose to mount the PSU with fan drawing air from the case interior. Effective intake would require less filtering, so there will be some fine dust getting into the PSU works anyway. And the case is slightly less pressurized, since case air is exhausting through the PSU.

I've thought about flipping the PSU, since I have the casters. But it isn't a priority, and I haven't done it -- not yet.
