At work we have some Dell xSeries servers (3 xSeries 306's) and the mounting rails that came with them. We need a server rack, square with vertical rails in front and back. I've never looked at racks before so I'm not sure if they are all compatible with our servers. With only the 3 servers we just need something probably 36"-50" tall. No need for doors or anything fancy. Reps to anyone who can provide some good links and information.
