Chip allows gamers to safely run Phenom-processor-based systems at speeds of more than 3.0GHz using a technology AMD calls "Advanced Clock Calibration."
Shuttle's XPC H7 5800 is unique mostly for the fact that it's the smallest system we know of to offer multigraphics card support and Intel Core i7 CPUs. If its options sound gamer-friendly, its price and configuration quirks are decided turn-offs. Unless you demand this particular balance of size and power, we'd look elsewhere.
In a normal economy, we'd expect that Falcon Northwest's new Core i7 FragBox 2 would wow us with fast performance in a compact case. Instead, the price of this system as configured has been severely undercut by a competitor. An improved warranty takes the edge off somewhat, but the new market reality makes it hard to recommend this PC.
Maingear's X-Cube small form factor game PC has received a cleverly redesigned case and boasts strong bang for the buck in its niche. We wouldn't necessarily pick this configuration, and you can find a better deal in a standard-size gaming desktop, but you still might be charmed by its unique looks and its decent value.
