Modifications and Upgrades
Since the Cube's demise, a number of Cube enthusiasts have made modifications to their machines. Some of the more popular upgrades are high performance video cards (complete with ductwork to allow the GPU fan to work correctly in the small Cube case) and third-party CPU upgrade cards (up to 1.8 GHz per August 2005); a few people have even modified their Cubes to take a dual-processor upgrade. A popular upgrade is the Geforce 2 MX, which exists in a version specially created for the Cube. Other popular changes include case modifications such as lighting and extra cooling. The Cube uses the same memory and hard drive components as a traditional desktop machine and these upgrades were common. Although the Cube uses a fanless convection-based cooling system, the mounting points for a standard desktop cooling fan are already in place. Upgraders of the Cube often take advantage of this to add a cooling fan to the system.
