Antec 900 - $80 after promo and MIR

Antec Nine Hundred Black Steel ATX Mid Tower Computer Case with Upgraded USB 3.0 - $80 after promo EMCNGHC52 and MIR (both expire 4/2/12)

Excellent unRAID case for a 9 - 15 drive server.

Looks like the power supply mounts on the bottom, but from the pictures I don't see any holes on the bottom for the air to go through. My Seasonic power supply when mounted correctly, has a fan on the bottom and would need holes for the air to get through.

I think you are right.  I've never used the Antec 900, just the 902 (which I believe does have holes on the bottom).  Can't you just flip the PSU over so that it pulls in air from inside the case?  I prefer that configuration anyway.

Also a great case if you plan on growing with your build.  I started with a 902v3 and have now moved to an Antec 1200.  They look great side by side as well.

If you flip, all the screw holes don't match up. I think you get to screw in 3, not 4. I would really rather NOT have any power supply pulling in HOT air, as compared to pulling in much cooler air from the outside. I ended up buying an Antec 302 case, which is just like their famous 300 case, but with some mods, power supply filter and all that jazz. Along with USB 3.0 too. Not for unraid, but for a single system build. Really can't beat the price.
