I think you'll have an easier time finding a suitable miniITX board and an adapter for the PSU connector.
well here's my problem, i have a slimline s3100n which comes with a micro-itx (7.5"x6.4") board and a 24 pin mini power connector, my problem is that i can't find a micro-itx board to replace it with i can only find mini-itx with normal size power connector and i can't replace the power supply because of the size of the case, i found the original mobo on eBay but at $100+ for a amd borad i feel like I'm buying my third nut.
here are some pics:
Yup. Either get the power adapter, or buy a DC-DC PSU (which you should do anyway).
Using an inverter is just going to mess up the next board you buy too...
There's PLENTY of room in there for a DC-DC PSU.
Anybody who makes significantly more money than you do.

Progress (Phase one):
You may be subject to HP's use of a motherboard that doesn't follow any standards. They are known for manufacturing components that won't work with anything that follows accepted standards. I don't know if this board is that way or not.
IF it only meets HP's standards, then your only option would be to get a replacement board from HP.
I'd say, get a mini itx board, a new case,a nd new psu, and be done w/ it.
I hope you kept the case + PSU, could bring a couple of bucks for you on ebay or something.
