When the Silverstone Sugo SG01 came out in 2005, it was seen as a boon to the DIY Small Form Factor system builder. It wasn't much bigger than a Shuttle P-Series chassis, yet allowed us to use our own mATX motherboard and full ATX power supply.
However, there were some issues with such a small chassis. There was very little room for a large fanless CPU cooler, and if you were to install an ATX 2.0 PSU, the cables would probably fill the entire system. Silverstone has given us another look at the SG01, along with 2 more components designed to be use with it to make building a SFF easier, quieter, and just plain better.
