Thanks for the response. Several boards actually don't seem to have internal headers for USB3 (P-DS3, A-D3H-B2, AP-D3) or they don't have eSATA. The Z68X-UD3H-B3 seems to fit the bill (though on the overlocking it is supposedly not that strong). At $160 it is at my limit but doable. The biggest issue I see with this board is reports of BSOD, occasional reboots, etc with certain USB3 devices connected. Is there a workaround for this?
