From "batfan06": 

"Started with a 1/6 RC Batmobile Tumbler from Walmart. Next I dremeled out all the RC gear to make room for the computer components. Then I made an aluminum plate to reinforce the Batmobile chassis. I installed all the LED lighting in the body incorporating 7 LED hard drive activity lights - 2 in front, 1 on each side and 3 in the "jet exhaust" to change it from blue/amber to blue/amber/red. Figured out the computer parts layout and installed them with necessary mods. "Stealthed" the on/off switch into the top of the car and manufactured a remote DVD eject button (hint: it's the brown button on the right above the DVD). Voila! You have a Batmobile PC. AMD Sempron 2800 , 40 gig HD, 736 megs of DDR400 ram."
