Agree with admiral. Unless you want HD audio onboard, AMD gets the job done cheaper.
It's too bad intel hasn't released Clarkdale based CPU's around 2GHz with all of the integrated goodies. Something around $50-60 or so. The i3-530 is just overkill for HTPC.
Sorry to throw a possible spanner in the works, and bring up intel again, but they do a cheaper clarkdale processor, and its aparrently really quite good. (overclocks to like 5ghz if you want)http://www.newegg.com/Product/Product.aspx?Item=N82E16819116283&cm_re=g6950-_-19-116-283-_-Product
That amd build looks good though
