I don't know how to build them nor do I have the time. Looking for a DC-DC power supply that can connect directly to my cars battery and then attach to my motherboard (c3 EPIA 800 mhz)

Would be nice if it had a 12 v output plug for my monitor.

I would like for it to be small in size so I might be able to put it in the cpu case.

Please PM me with any suggestions or offers to sell.
