Hardware
Processors are cheaper and it has released some new models but it is more on the side fyrkärniga the things happened and it is not needed directly in a HTPC.
4000 series of graphics cards from AMD / ATI with integrated multi-channel audio via HDMI, I will look closely at. It is probably a very good choice along with an Intel CPU if you do not want to use integrated graphics.
For the power supply side, I thought to include a 80 variant with around 300W capacity because it is enough for a HTPC.
Should consider integrating a Solid State Disk (SDD) from hard drives, and Samsung F1 performance options.
As far as sound cards, it is mainly cards from Auzentech and Asus, to cope with bitstreaming of HD audio, I was going to write a little about.
I have found some exciting new keyboards, mice and remote controls, but do not know if any of them is recommended. Can probably wait with that until I read a little testing of them.
Recommendations of memory and cooling may be enough as they are. Similarly, TV card if I do not take up the Hauppauge Nova-TD, which I use myself.
