What's keeping me from Epox is their bad history of problems, with the AGP slot fiasco, where the capacitor interfered with a large AGP card, their bad supply of capacitors, which resulted in poor quality/high RMA (they either got scammed, or they intentionally bought grey market caps), and this thing about the regulators running very hot.

Asus on the other hand, really doesn't mess around. They're very close to Intel, when they design mobos.
