Stay far, far away from the Biostar tz68a+rch board. I bought two. The first one didn't boot up, and fried my gpu (motherboard "popped" when Microcenter tested it). The second one didn't boot. After troubleshooting, I discovered it had a bad cpu locking mechanism. The computer would boot when it wasn't locked in, but shorted when it was. Ended up trying a third time with a gigabyte motherboard, which was up and running in 10 minutes.
To be honest, I'm extremely unhappy with microcenter's return policies as well. The first motherboard I went to return, they told me I'd have to pay $20 if the motherboard was fine (I took the risk because I'm no newbie). I waited an hour in the lobby while the tech tested it. They made me eat the cost on the 2nd motherboard, because they claimed some of the pins were bent (none of them were, there was discoloration on some of the pins from the motherboard shorting out).
All in all, I wish I hadn't jumped on this. Well.. I wish I'd jumped on it and purchased the gigabyte/asus instead of the biostar.
