Recommendations for mobo / cpu.

[NaturalViolence]

430 watt is way overkill. Take a look at my HTPC thread for some ideas.

I'm going to recommend the exact opposite of your current setup. I would strongly consider going the AMD route if you're on a tight budget. Intel IGP drivers still suck. And you don't need the cpu horsepower of an Intel cpu for a system like this.

Edit:
You're going to have to bump your budget up to $350-375. $300 is really pushing it for an HTPC.

Here are my recommendations.

SSD ($90): http://www.newegg.com/Product/Product.aspx?Item=N82E16820147247
CPU ($60): http://www.newegg.com/Product/Product.aspx?Item=N82E16819113282
RAM ($50): http://www.newegg.com/Product/Product.aspx?Item=N82E16820231474
PSU ($45): http://www.newegg.com/Product/Product.aspx?Item=N82E16817151077
Mobo ($70): http://www.newegg.com/Product/Product.aspx?Item=N82E16813128659

Total cost before shipping: $355

I would recommend spending more on the mobo (get a CIR supported model) and case if you can stretch your budget even higher. $450 I think is ideal for an HTPC with an SSD.
