As an update, I went with Magic Micro out of Cleveland, Ohio. I order an ASUS motherboard with an Intel E6600 processor, 2 GB RAM, 1 nVidia PCIe x16 video card and a case that has a temperature readout and a big power supply. I also included a Coolmaster (i think??) cooling system. The mother board has 3 PCI slots for the addition video cards to run a total of 8. I added my own DVD R/W, Seagate EIDE hard drive and mouse/keyboard. That seemed to be the most logical solution to the whole issue. The memory can be upgraded to 4 GB, but I doubt I would need that. The case also include 2 additional fans (1 on top and 1 on the side of the case) to remove any rising hot air in the case and any heat generated by the video cards (fan is right on top of the PCI slots). All of that for around $600 delivered.
