PC Perspective take a look at the Silverstone SG-01 Evolution SFF Chassis:

With the changes Silverstone made in their version 3.1 of the SG-01 and the addition of the optional FX121 cross flow fan and an 80 mm fan we had hanging around, the SG-01 is now a quiet but extremely effective cooling environment for our AMD64 3500+ system even with our 10,000 RPM WD Raptor hard drive installed.

There is no doubt, in my mind that, Silverstone has a real winner in the SG-01 and I wouldn't doubt it one bit, if it became the premier SFF on the market. Do I have any complaints? No, not one!
