I've done a lot of working with Xboxes with no dvd drives, and 2.5" hard drives (see the battery powered xbox project in my sig). It can be finicky and sometimes frustrating, but the reward is very small size and low power cunsumption (xbox mobo+2.5" 80gb hdd+7 inch TFT LCD screen+speakers = 50-60 watts, @ 12VDC)
So far I am the only person to have an xbox that runs on its own internal battery pack.
I like the idea for the project, very original and bold, kinda like when i said "wouldn't it be cool to play xbox anywhere, even if there isn't an outlet" almost a year ago.
I would very much like to contribute to the project.
I work part time at a hobby shop, mod xboxes as a side business, and Im in my fourth year of engineering and design in high school (along with AP Calculus and AP Physics), and plan to major in mechanical or electrical engineering in college.
