for some reason the links dont work for me. It looks good, i just dont know what type of ram you chose. Im assuming its ddr1, so you should be fine.
You are missing some parts to the pc though. You need a PSU. I would recommend fortron, Zippy, they are very good are at good prices.
You need a wireless adapter for you pc that goes into a pci slot, or one that is USB. You will also need a wireless router or access point.
Using 2x1gb stick will work fine.
My current specs:
Biostar TPower x58
XFI GTX260 Black Edition
640 WD Caviar Black
Vista Home Premium x64
