Summary: I've pushed this system way past its typical use case, and 3 years later it still works. I haven't touched any of the OC settings in the BIOS, which probably helps the longevity quite a bit. Biostar got it right, except for the NIC.
Pros: I purchased this 08/2012, and it's still working! Started as a low end system that has turned into a home workstation, and it handles well.
Cons: I've noticed the network interface resets frequently and sporadically, as others noted, but after 3 years, hardly a huge con. Just wish I didn't have to purchase a NIC because of component failure.

Pros: I'm a gamer and change my installations regularly. I play everything from Eve to World of Warcraft to War Thunder on high settings and have no issues. It's not the most pro setup, but I do anything I want so I see no difference. So far, so good!
