Reviews of the machine have praised the pace of data transfer and huge hard drive space it offers and the processing unit itself is smaller than standard PC towers and medium enterprises that fit under your desk, making it ideal for limited workspaces. However, these sorts of computers tend to be low power (especially when running games). In general, the cases also have mini expansion slots and drive bays, and you will need to extend the system’s power via USB, FireWire or peripherals, so make sure your external hard drive has a large number (and variety) of ports.
