I've had my truck-pc finished for about a year now and I LOVE it. I still need to figure out a front end, but that's more a laziness problem then anything else. I have a HP Slimline PC run off an inverter. I'm looking to shift to a dc-dc power supply since I do get some noise from the inverter that is noticable in the screen. I just don't know how difficult it would be to pull the existing power supply out and replace it with a dc-dc. I would also like to piggy-back my xenarc on the power supply to clean up the power signal.

Anybody else ever swap out a ac-dc for a dc-dc? on a slimline? It seems the M2 is a popular choice.... I'd probably go with that option.
