Bill, I’m sure you’ve taken a gander at the recommendations & links listed in the PDF of the downloads page, right?
The only thing that jumps out at me is the fact that this machine has no video card:
Video adapter, bus: With the GV chipset, the integrated graphics is always enabled. Plugging in the PCI card does not disable it and does not require the integrated graphics to be re-enabled
Video adapter features: 3D/2D Controller (Microsoft® DirectX® 9), VGA integrated controller, RAMDAC integrated (400 MHz)
Graphic Subsystem Video Card Memory: Graphics memory is shared with system memory. Graphics memory usage can vary from 8 to 128 MB depending on the amount of system memory installed and system load
This wouldn’t directly prevent you from running EMC2, but some machines with built-in video cards (as opposed to a separate video card) have problems with losing steps (again, see the PDF for an explanation).
