My desktop-PC's Motherboard just died yesterday... So maybe it is time to buy an all new PC!
What I have in mind is to try to build a Desktop-PC-Bot around a mini-ITX MB: It should be a desktop-PC when I am at home and a robot when I am out (or when i don't need the PC). I will use a commercial or homemade chassis and put outside wheels, PING, camera, and all other fun stuff for a robot, and inside the mini-ITX, the EZB, etc...
My concern is about power. I want a relatively good motherboard (like this one http://www.gigabyte.com/products/product-page.aspx?pid=4338#ov) and CPU (like this one http://ark.intel.com/products/65515/Intel-Core-i5-3475S-Processor-6M-Cache-up-to-3_60-GHz) and I think it will need at least a 300w alim. It is not a problem in PC (connected) mode, but I don't know if it will be possible to find a battery that will handle the whole system in Robot mode... What do you think?
