WhiningDog.NET has their review of Shuttle SS51G XPC Pentium 4 barebones system up.
This past year has certainly brought upon a change in the Do It Yourself (DIY) computing landscape. We've seen the growth of a whole new category for the PC market - the small form factor (SFF) market pioneered by the likes of Shuttle and others. My first SFF system was a system from American Media Systems known as the gBox. This system was based on the Shuttle FV24 motherboard. Using this same motherboard, Shuttle had also introduced the SV24 barebones system which became very popular among the computing enthusiasts. However there were a number of complaints with this model. It only supported the Pentium III, had only one PCI slot, had a fairly weak integrated video sub system, and was fairly loud.More information at WhiningDog.NET
