The RX-3393 3U rackmount computer is a Pentium workstation that has a lot of nice features to recommend it. With its short 17” inch depth, it can fit in a portable rack. With three internal 3.5” drive bays it can still handle a RAID 5 configuration. There are no height or length restrictions to worry about when populating with your add-on cards. It possesses a powerful cooling system with two 60mm intake fans in the front and two 60mm exhaust fans in the rear.
