If you’re looking to build your own HTPC (Home Theater PC), but want it to take up as little space as humanly possible, you might want to check out this Mini-ITX board from Aaeon.

The EMB-820T won’t be a powerhouse by any means, but it will support AMD’s Athlon-based embeded CPUs, which should give you enough to do most tasks. The big news is that it will include TV out and 5.1 surround sound, all on a SBC (single-board computer) unit.
You don’t have a lot of room for expandability, for obvious reasons. They do include a Mini PCI and a PCI slot that can be used for a network adapter, or whatever else you should choose. The board is available now, but they have not disclosed the price.
The full specs as listed b Aaeon are as follows:
