I have a 42U (I believe) server cabinet. It has an APC Smart-UPS 1500 and two E-M-Solutions power supplies with cables. It also has six 140 mm fans installed at the top of the case. Rear door is lockable, front is lockable as well, but there's a broken key stuck in the lock. Front door is also removable. All side panels are removable. I also have a few keyboards and cable management racks as well. I'm not sure exactly what model the cabinet is, but it's made by Sun Microsystems, and the dimensions are 74"x24"x39" (Height x Width x Depth). If you have any questions please feel free to contact me at the address provided, Thank You!
