Aspire X-QPack PC Case
 

The X-QPack PC case from Aspire is compact, lightweight and comes with, of all things, a carrying handle. The X-QPack comes in five colors, features windows on three sides, a 120mm. cooling fan, removable motherboard tray and a 420 watt power supply all of which are uncommon in a mATX PC case design. The X-QPack is described as a "grab and go" PC case. It's not much larger than a toaster oven.
