I just built a computer using an ECS K7VZM (the micro ATX version of the K7VZA), and it runs beautifully. This computer was for my girlfriend's sister, so I didn't really get to play around with it as much as I would have liked. In any case, this is definately a solid, stable mobo, however, it is NOT good for overclocking at all. I personally am going to be upgrading my computer in a few weeks to the ECS K7VZA (rev 3) and a T-Bird 1GHz 266FSB.
