I love my case, and it seems to be a very popular case. Alienware uses this case for some of their systems. I have the Antec SX1040b. It's the black version of the SX1040 (everything else is the same). It is also the same case as the SX1030, and a few others...and I think it's offered by different companies with different PSUs. Mine comes with an Antec 400W PSU. it's got 4 internal drive bays, 2 external 3.5" bays (in the same cage as one of the internals). 4 External 5.25" bays. It's got tons of room to move around in, 4 80mm fan mounts (including one in the HD cage), and a closing (locking) door that makes the whole thing look pretty sweet. The drive cages are awesome. They slide in and lock in place with a lever. It's a large, heavy case, but it's really sweet.
