Deep-ITX is used a lot to use standard registered ECC ram in ITX narrow chassis... Other derivative from ITX (mainly industrial or server use): thin-mini ITX, without backplate and with limited high and the ITX/DTX with dual PCI (real DTX is based on mATX)

and the ITX/DTX with dual PCI (real DTX is based on mATX)

I've been irritated for years that DTX hasn't been more common. Most ITX cases would support a DTX board, thanks to most GPUs being dual-slot. Even if you're only sticking with a single PCIe slot, the extra space on the motherboard would allow so much room for other devices. Or, that extra space could allow everything to be soldered to one side of the board, making manufacturing (and in turn, the board itself) cheaper. Obviously, there should remain to be ITX boards, but it just seems like a major missed opportunity.

It's mainly because we put 2 slot graphic card on ITX motherboard on main segment... it make that most ITX chassis are in fact DTX too.

Oh wow, what a wonderful motherboard for a SSF server. Can someone get this motherboard in bed with a HP Proliant microserver and let them have some babies?
