I have a friend who already got rid of here cheap rig. If I had known about the rig and had she discussed it with me, I would have gotten it and used it exactly what AVIATION just said. But right now, I have my computer setup in the following configuration:
40GB Main Internal HD - Other Programs
$100 80GB External HD - For FS9 [will be removed when FSX comes out].
$140 250GB External HD - For X-Plane v8.21
As you can see, I have seperated the sims from the main computer drive so that I can save space for the main HD. The rest of what's in the main drive is just tools for developing my projects. Nothing more.
