While the machine manages to run as a gaming system, it was a little disappointing in its port array: It has a total of six USB 2.0 ports (four in the back, two on the side) and a multifunctional card reader. Although this is plenty for a casual machine, those who are a little more involved in PC gaming may find those ports lacking. Peripherals, external hard drives, and other gadgets will quickly occupy every USB port. Firewire, eSATA and USB 3.0 options for speed and convenience would have been nice as well.

Overall, the IdeaCentre B520 is a giant step forward in making a powerful all-in-one machine. The hardware is comparable to that of dedicated gaming machines, and the features mirror those of a great media center. The system allows you to be versatile with your computing needs. However, it does lack some features of a high-end gaming rig while retaining a high-end price tag. If space is an issue, but you still need some serious computing power, this is certainly one of the best options available.
