Actually, the Enermax is
NOT "considerably more compact," and the PSU position in the Coolermaster
IS near the top of the case.
The Enermax Venus and the Coolermaster ATC-620 are
about the same size. The Enermax is actually thicker by about 1/2 inch (both can take full-height AGP and PCI cards), and about the same depth (17 inches). The most obvious difference is in the width, and even then the difference is small-- The Coolermaster is about 3 inches wider.
I'm not sure why you would think the way the PSU is mounted in the ATC-620 is "wrong". If you stand the case on its side like a tower, the PSU
IS at the top of the case. And if you sit the case flat like a desktop, you can mount the PSU in two different orientations. I have a computer built with the ATC-620 using a Seasonic Super Tornado 350 PSU, with its
120mm fan face-up so that it can draw out hot air that has risen to the top of the case, just as you wanted. It will give you MUCH better ventilation than ANY uATX case using an SFX PSU including the Enermax, 80mm fans or not.
For the ATC-620 I built with the Seasonic ST350, case temps never rise above 31C when ambient is 25C. Much better than many SFX-psu cases I have built with.
I like having a choice in choosing the PSU. The ATC-620s I've built with the Seasonic PSUs are MUCH quieter than the Enermax. And you can throw in your favorite brand of PSU in there, including Fortrons, OCZs, Antecs, what have you, with higher amp ratings if you wish. You won't get such a wide choice of selections with cases using SFX PSUs.
The Coolermaster is almost the same size package as the Enermax but better options. Functionally, the ATC-620 is the superior HTPC case.
