I was actually hoping for something similar in a mATX A64 board but with DVI. I looked at the MSI RS480M2-IL which is very close to what I want but no DVI.
This would be for a HTPC. I was also planning to mod a Mac G3 case with a PC and would need a mATX board for that. Neither machines would need to be that powerful but having the option to upgrade to dual core CPU's and PCI-E graphics cards for full upgradeability is what I wanted as well.
Now if only someone would only release such a board.
