Spec me the smallest pc for running vista media centre

[Conanius]

As title, need something that will run vista ultimate/home premium. Just need it downstairs by the tv with a usb freeview dual tuner in it. whats the smallest box I can get that will run this? Should add, doesnt matter if it doesnt have a DVD/CD drive

A shuttle would probably be best, although perhaps not the cheapest... Although if you want it to fit in, an Antec Fusion would also be good.

If its the absolute smallest you want then check out aopen mini pc's. They are the same size as a mini mac. Mine has a built in dvd, T5500 C2D, 80gb 2.5 drive with 2gb ram.
It runs xp but I suspect vista would also run if you are that way inclined.

or Hiper cases or something in an ITX format 9new asus B224?) looks good
