Thanks for your replay all
So I guess the AMD option is the one to go for; Well known hardware, onboard nividia grapich that can handle HD with vdpau(not shure if this is posible in LMCE, but it works with XBMC I hear) and UI2 overlay. 5.1 sound and NIC working(not shure out of the box doe!).

Lmwasher:
Checked out the Phenom I and II with the "e" version both at TDP 65w. But none at stock at my place. I will see when I have the system up and going(need to see the WinTV-NoVA-TD-500HD working in LMCE), maby upgrade to one of those. (of cauce it is more than twice the price at the moment...) I am also planning an web admin server for the media files. So maybe I will jiggle the HW around later.... if you catch my drift
So this one is going to be low cost and low power consumtion, with enough power for 1-2 MD's I hope
