The Iwill ZPC is the smallest PC case we've seen to date, measuring a tiny 184mm x 54mm x 263mm. If you're after the ultimate in super compact computing, look no further than this unit.

The ZPC is housed in an attractive Perspex and steel casing, with internals accessed through the rear I/O panel. Once you've removed the tiny screws, the whole PCB slides out to reveal the machine in its entirety. With space only for a single 2.5in notebook hard drive and slim slot-loading notebook-style optical drive - this doesn't cater to the peripherally proud user with beefed up hardware, but it does save on space.

The compromise for the space is that you don't have much room to play with, which also limits future upgrade options. You also only have provision for a single DIMM and no PCI or AGP slots.

Although ideal as an ultra portable device to take with you wherever you go, it won't be as cheap to set up as a larger barebones due to the additional cost of notebook-size components, but it is small and proud, and a slick addition to the living room.
