It does have feet, the case is designed to intake air from the bottom. That's also where the hard drive mounts are, but I wanted cooling instead, so I went with the M.2 drive.
With the fan being such a tight fit under the GPU, I know it's not getting full airflow, but with it being an AP fan, it actually does a very good job. I figure the AP fan gets just as good (or better) airflow even half blocked than a thin 180mm fan. And besides that, IMO it just looks awesome, the way it swirls out from the middle of the GPU. In person it basically looks like that fan grill IS the floor of the case.
I'm happy with the temps anyway. It Idles in the low 30s with the pump running and the radiator fans turned off, just the AP running on low. On full load it maxes in the mid to high 50s. GPU is overclocked to 1.5Ghz and CPU (i5 4690k) to 4.6Ghz. I will be adding a second DC-LT pump as well, I already have an extra (extracted from a Cooler Master Eisberg Solo) just waiting on the pump top, that way I can run the pumps on lower speed (quiet) and get better flow/temps.
Also... I don't know why the avatar looks like that... I shall attempt to fix it.
