Component Compatablility?

Hey TH guys!
I'm attempting a computer build, and while Ive looked this one over, I cant seem to find any errors with the part compatibility. I figure its best if some guys with experience look this one over though, so heres the list:

Rosewill TU-155 II 500 Black Computer Case with 500W Power Supply: http://www.newegg.com/Product/Product.aspx?Item=N82E16811147117
G.SKILL Ripjaws Series 4GB (2 x 2GB) Desktop Memory: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277
BIOSTAR T AM3 AMD 790GX ATX AMD Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813138163
AMD Athlon II X3 435 Rana 2.9GHz 3 x 512KB L2 Cache Triple Core: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103724

I already have a HDD and a DVD drive, so those wont be necessary.
Thanks a lot guys, your a big help!
