This is all very flexible, so please feel free to tell me where I've gone wrong (and right hopefully!)

I'm planning to use this as a PVR to record FreeviewHD (maybe using GB-PVR), as well as a media player using (probably) XBMC as the front end for a server which stores all my media in another part of the house.  Everything on the LAN is gigabit.

Case: Silverstone LC03
MoBo: Asus P5QL-E
CPU: Intel Core 2 Duo E7300
Graphics Card: Asus 9400GT silent
TV Card: Hauppauge Nova T 500HD
PSU: Corsair 450W VX

Anything glaringly wrong here??  All thoughts appreciated!!
