Case wise, Supermicro and Chenbro are the top high-end gear. However Norco is more of the budget line. Never heard of AIC

PSU Wise, Zippy hands down. Supermicro and Sparkle don't come close to a Zippy. Though a Supermicro is significantly better than Sparkle

Mobo wise, Supermicro takes the cake here. Asus and Intel are more value oriented. I hardly ever see Tyan recommended around here

RAM wise, they're basically all the same. However Kingston tends to have the higher compatibility rate with Supermicro motheboards
