I have a Dell Dimension E521 and I am thinking of upgrading the motherboard to allow me to fit a 2 slot graphics card. I saw on the internet the ASUS NCCH-DL Dual Xeon/875P/64Bit/FSB800/GBE/ATX and was wondering if it will allow me more slots for a sound card, graphics card, and the cooler and if the actuall motherboard can fit in the tower. Please send me a private message if not post, thanks...
