The two-stage lock is one of my favorite features of Thermaltake's cases, and one which I think all companies should include. Because you do not have to remove the bezel to get at the chassis, you can effortlessly add or remove drives, or access the front of the case.
The chassis has very nice construction, even if it is steel. As one would expect from Thermaltake, the case comes preinstalled with fans- two 120mm fans (intake and exhaust) and a 90mm window fan. These will save you a good deal of money instead of having to by them aftermarket, probably around $30. Plus they are Tt brand fans which have 4-pin and 3-pin connections, perfect for a case fan.
The Soprano features the front USB, FireWire, and audio jacks on the top of the case. This placement is not as accessible as on the bezel but it does give you a good place to place the accessories when they are plugged in. A lot of people prefer this on the front, but I think the top is a good idea, especially for items like a card reader.
