I agree, which is why I was eager to do this one. Mini-ITX is a lot more capable than most people realize.
There is a small error in one chart though (correct in the text); the H81M-ITX only has two SATA 6Gb/s ports, not four. I'm sure this is my bad from copying parts of a template.
I've seen commentary elsewhere urging higher OCs on a Pentium, and I'll be testing that. I'm also going to find out if my original sample is just a dud, or if the VRMs on these boards just weren't suited to overclocking, despite staying cool, and despite being rated for 84W chips, not just this little 53W one. I decided to buy another G3258 myself. Overclocking isn't one of my primary interests, but I think it's necessary to find out what was limiting me to a mere 4.0GHz. I could hit 4.2 and boot into Windows, but it was not Prime95 stable. Temps were not the issue. RedJaron got his I believe to 4.3GHz, so I tried voltages that bracketed his, and got nowhere. I'm hoping I got a dud chip, as one of these on a H97 would be a reasonable daily driver if I can run up the clocks a bit. That's why I also bought another Gigabyte B85 board though (not mITX); I could not return the one Tom's bought for my tests because it is the first motherboard on which I've ever mangled LGA pins, in this case badly fumbling the plastic CPU socket cover. I chose one specifically for weak VRMs; it appears to only have two phases on it.
I've got a mere E8200 at work, with 4GB of RAM, and if it can handle layers of centrally-managed, GPO-enforced "stuff," MS Office, multiple browsers, remote access, and more, then for even older games, the G3258 with 8GB and a modest gaming card like a GTX650Ti or HD7870 ought to do quite well.
