Pros: Looks really nice, and performance was awesome when it wanted to work.

Cons: Not Windows 8.1 compatible, they supposedly have the drives that will allow it to work with Windows 8.1 but the drovers don't work. Tried with a single card and with dual cards and with each configuration the systems completely froze, nothing responding at all. It works for about an hour with the version 13 drivers and then freezes again. Had to hard reset the system to get it going again.

Overall Review: Don't waste your money on this card if you are planning to upgrade to windows 8.1

Pros: Very secure with all sides lockable

Cons: Additional cost for shelves, trays and L brackets.

Overall Review: Ordered a 36U and they sent me a 48U rack
