PC Stats posted a review on the Shuttle XPC SN27P2 SFF Socket AM2 Barebones

Shuttle's latest Small Formfactor PC is its XPC SN27P2 which is based around nVIDIA's nForce 570 Ultra chipset and supports 940-pin socket AM2 Athlon64 X2/FX and Sempron processors. There are a whopping four 240 pin DDR-2 DIMM slots, making this toaster capable of supporting up to 8GB of DDR2-800 RAM. If that wasn't enough already, the BTX-style motherboard layout means you can install a PCI Express x16 videocard with a dual-slot heatsink! It's unheard of! Overall the Shuttle XPC SN27P2 Small Formfactor barebones PC is a nice package - it looks great and is built with reducing an impact both in the space it occupies, and in the amount of noise it generates.
