In Win R300-01-S500 3U Rackmount Case w/ 500W PSU

This 3U rackmount chassis from In Win is designed for standard ATX size motherboards, but is large enough to fit full height and full depth expansion cards. It does not use standard ATX size power supplies, though - instead it comes bundled with a 500W unit pre-installed. Also included is an array of four 5.25-inch bays on the front, behind a lockable, flip-down panel.

Please note that while full height cards can fit in this case, those with power connections along to top edge of the card (rather than the end) will likely not work. There is very little space between the top of the expansion card slots and the lid of the chassis.
