The layout wasn't the most impressive. For instance, I was not at all happy with where ECS decided to stick the auxiliary power connector. I was also unhappy about where the IDE connector was located. To me layout is one of the most important aspects of a motherboard, so these defaults really brought the P55H-A down a few notches in my book. I was also surprised that the Driver CD didn't work. Vista has been out for a while now, and 64-Bit is nothing new. The fact that the Driver CD didn't support 64-Bit Vista is just ridiculous.
