All parts are preferable to be under a hundred dollars, since I pay a 20% tax on computer parts over $100, and the shipping is more expensive too.

About the case, I can't order one because the shipping to my country will be way too expensive, there is no htpc cases on sale here, the only one I've found that some people on the net say they use as htpc is the Cooler Master Elite 360, the other cases are normal towers primarily thermaltake is what they sell here.

Well I would stick with AMD and for a HTPC/ Gaming, rather get the X3 440...It would suffice...

Mobo - Get the ASUS/ Gigabyte 880G

PSU - That 400W can even run HD 5770...So not issues with that...

Graphics card - +1 for the HD 5670...stick with that if you want to do some gaming...
1GB would be nice, but it costs above $100 though...

RAM - This is a good one -
