Complete computer upgrade...HELP!!!

[aksd]

I need an expert opinion on a 775 mobo.

Here are the specs (all the hardware listed is already purchased)

P4 651 3.4ghz
1gb Buffalo ddr2-4200 sdram 533mhz d2u533b
nvidia 7900gs 256mb PCI-E
Sony CD and DVD combo Drives
Hitachi 80gb 7200rpm HD
420W Antec PSU

I bought this hardware to go with my computer, long story short, It didn't work with my system. Now I'm to the point where just want a Mobo and case. Don't care about features and "bling-bling" just as long as it works.

So can someone point me towards a good budget Mobo? Preferably micro ATX.

Thanks,
