Yeah, thin ITX boards top out at PCIe x4, but I don't see that as being a big deal. PCIe x4 (at 3.0 speeds) has virtually no performance penalty vs. x8/x16.The bigger issue is that it's only provisioned for 25W to the slot on thin ITX (vs. 75W for x16), which means an independently-powered riser is practically mandatory.An AC adapter is what I want to avoid, both because it's awkward, and because it puts a fairly low ceiling on power draw. Getting it all together in a single flexATX unit seems more ideal to me.
