Build sanity check before I start buying

HI, been looking at a HTPC build for a while now and quite frankly I'm fed up of reading and want to start buying bits!

So can anyone see any glaring blunders in this build?

Main uses will be PVR (front & backend), and streaming AVIs and MP3 from my NAS.
Not sure if I'll want to do any encoding of PVR recordings - depends how I get on with disk space.
Definitely want to run LINUX so linux support is v important (and a was fairly major hurdle for finding supported DVB-T/T2 cards - which worries me about the rest of the hardware - will the motherboard be OK?).
