Pros: Has space enough for 12mm drives (if you remove the cover from the drive tray) good metal construction of the housing, and trays, good air flow with dual fans, powered by single 4 pin molex. The SATA connections on the back allow for latching cables, not necessary but I'm always interested in positive locking equipment. I installed this unit in a Dell T620 with some modifications (see Cons) using a "StarTech Model SAS8087S450" also purchased from Newegg and it works great for SATA drives. I'm running RAID mode but I imagine that standard use would also work well.

Cons: 2 cons, not really big but worth losing an egg. First, the latches on the drive trays are plastic. (like I said, not a big deal) Second, the screws mounting the drive need to be really shallow. The treads cannot extend into the tray/drive path at all, the trays will run into the screw if more than half a thread is hanging into the drive bay. This was a problem as the screws supplied by Dell for servers (and desktops) need to be cut or ground down to allow the drive trays to move in and out. For the system builders out there, this unit does ship with shallow enough screws for most mounting situations, credit to StarTech for that. However, the fact that non StarTech screws render the tray operaion useless loses an egg in my book

Overall Review: The aluminum is .080 inches thick (give or take) so the sidewalls are strong enough if you cut or grind down screws to fit slide rails or other non traditional mounting methods. I would buy another if the need comes up

Pros: Worked first time with a Dell T620 on board SATA controler. The motherboard uses a SFF-8087 for 4 of the drive connections, and this cable clicked right in nice and snug. The SATA ends have latches that gave a reasuring click when pluged in to the devices.

Cons: The cable was a little longer than I needed, but it tied off to the side nicely. Still gets 5 eggs!
