I simply use $60 MSI mATX h61-p21 boards. I have two of them and each runs 4x5870s. If you're going to use 4x7970s I may consider putting them on risers with Molex plugs.
That looks like a pretty good miner platform for those with extender cables, as it is all PCIe 1x slots with no legacy PCI, and a Celeron G440 can go in that ($65+$41 free ship on NewEgg). I started looking at AMD boards figuring that a Sempron plus the least-expensive brand-name 4xPCIe motherboard would be cheaper than an Intel platform.
For later resell though, a motherboard with two 16x PCIe slots plus a 2.8GHz AMD CPU will sell easier than a mATX no-PCI-slot board with a 1.6GHz Celeron - you can sell the AMD with GPUs as a crossfire gaming system, but the Intel can't even be a media PC (only VGA out).

that is tru, but the 2 I listed has on mobo start and reset buttons for caseless rigs.
I've got your reset switch right here:

For power, just set the BIOS to power on after power loss.

I have two of those boards with G440s. I had to flash the bios for the boards to post with the G440s, but it was extremely simple. Other than that they have been working fine. I use a screwdriver to start the machines as well.

being able to hold down the power switch for 5 seconds to turn off a hung rig is valuable to me...   

You can always turn the switch on the PSU.

Excactly. Besides, if it comes to that you're doing something wrong.

I bought one new and one open box. I figured if either failed I could send it in as the new one. It saved about $20, but at this point they've been solid. With 4x7970s I would definitely put the cards on Molex risers though. I think I have to be pushing the boundaries of these little boards to supply power to 4x5870s.

I believe the 7970 uses less power then the 5870 so the Mobo shouldn't have an issue. Do you use the extenders with Molex (http://cablesaurus.com/index.php?route=product/product&product_id=28)? I'm thinking about buying this for my next rig. Have you used it with a USB Flash drive. I've had problems with some MoBo (Gigabyte specifically) not booting from the USB Flash Drives.

Thanks for the info!
