This short-depth 2U rackmount chassis from IN WIN is built for Micro ATX motherboards. It comes with two 80mm intake fans and has bays for two external 5.25-inch devices as well as four internal hard drives or SSDs. The expansion slots are half-height, due to the slim 2U form factor - so that limits what add-on cards can be used.
Note: In Win 15" Depth Open Bay Chassis (PSU not included)
Model: InWin IW-R200-O15
