Hi I'm the owner of 2 Asrock ION330Pro Atom based computers. (Black and White)
One system I have running as a media center.

And the system I'm selling was for my son but he got a iMac.

The system is completely working with all the items with it.

Atom duo core processor.
ION graphics (capable of doing 1080p)
2 Gb of RAM
CD/DVD dual layer burner
320 Gb hard drive
Ethernet
6 x USB
eSata
HDMI and VGA (HDMI to DVI dongle)
S/P DIF (6.1 Dolby working)
stereo audio out
stereo audio in

The (i)Rock works perfectly as a media center it does not consume a lot of energy only 20 Watts. It is small and quite.
With SL 10.6.4. it is rock solid.
You can have it clean installed with PLEX as media center app.

I have also PS3MC installed on it so it can trans code DVD's via DLNA to a DLNA compatible TV like Sony / LG / Samsung.

This is probably the best thing to a original Mac Mini but for half the price.

As I'm in Holland I will ship it to any corner in The Netherlands.

If you have a interest for this baby drop me a PM or respond to the link and we make a deal
