I was browsing Mini-ITX NEWEGG in the last hour or so. I saw prices ranging from from $40 to $240. Most under $100. Even the best rated ones seem to draw a few cons mostly to do with boards having problems. I'm assuming that is because people tend not to post about satisfactory outcomes. Most have some form of on-board graphics though the high end units intended for overclockers seem to omit that.


Mini-ITX is the form factor in all those HP Slimline desktop systems. Though HP has used different power connectors than the majority of the boards available.
