its not worth the headache. go for your build!
if you follow sean's awesome install guide for windows 7/8 here on overclock.net, he suggests turning off any hibernate or sleep modes as they cause excessive writes to your ssd. as far as I understand the issue: on some USB3 drives, going into sleep while you have a file open on the drive MAY cause it to revert it to your last save. and so if you are turning off any sleep or hibernate buffers as overclock sean suggests, there should be no issue at all..
asrock board is great too! heard there are some issues with the back msata slot, but i don't plan on using it anyways..
