I've installed the Mac Mini, external 250g HD, and USB port router. I still have to install the monitor and XM units. But I set it all up in the house first and it worked greate. Here are some pics.
Here is the console "bucket". I comes out by itself and is huge.
Here is the "bucket" with the brackets I made and the case fan I installed.
Here is the unit just before I put it back in the truck.
