MODTHEBOX.COM posted a review on the Kingwin Supernova HTPC Case

The sides of the Supernova HTPC Case are constructed from 1/2 inch extruded aluminum that provides strength while keeping the weight down. The rear of the case is also made from aluminum except for the motherboard I/O plate and PCI area which is made from steel. There are two 60mm fans to help extract the heat that were surprisingly quiet when tested in silence on the bench. The Supernova uses a full sized ATX spec PSU which is not included giving the end user the option to use a PSU of their choice.
