Mini computer

Since my hardcore gaming days are over I'm looking to downsize and use my space more efficently. I'm basically looking for a mini computer like the MiniMac except not mac. I've looked around and there seem to be a fair amount of barebones systems, most of them compatible with the pentium M from what I have seen. Then there's also the route of buying a mini motherboard but that would mean I'd have to make some kind of box for it myself and that seems like too much hassle.

What I want to know is if anyone has any experience with mini computers and can recommend me anything. I'm mostly going to use it for surfing, watching movies and some sequencing/not so reasource heavy audio stuff. Needs to have usb and firewire but I assume most of them has nowadays.

Any input is appreciated. Thanks!

I suppose I could but it would cost more and I'd have to get a screen and a decent keyboard anyway. And I don't really need a laptop right now.

I thought linux was an os.

I've looked at the Aopen XC Cube Mini MZ855-II and it seems to have everything I'm looking for. It's small and quiet, has an external psu (only 150W though). 1 low profile agp4x slot which means I won't be able to use my old card in it but there are a bunch of cheap low profile agp 8x cards to be found. Can I use these in the 4x slot?
It also has a low profile pci slot, room for 1 hardrive and 1 dvd burner. A bunch of usb and firewire ports and a memory card reader!

Thoughts?
