Quality. The thing is built like the Ark Royal. I can't help but keep opening and closing the door, which is a one-piece aluminium extrusion with a satin finish on the inside, it's just so satisfying. (I don't get out much.) With the 3 supplied fans it's virtually silent, and the amount of room inside and clever solutions make setting one up a pleasure. The only thing I didn't like was the engrish manual and the screwless card retention system, which ridiculously didn't take into account double-slot cards, or for that matter, SLi setups. Thankfully, you can ignore it and just use screws as normal but it does kind of miss the point. The projector is a silly diversion that doesn't work properly but the optional mesh/perspex window is a thoughtful inclusion, as is the little removable toolbox in the drive bay section. Well worth the money if you're looking in this price range.
