I believe the biggest difference is the E model has gigabyte lan routed through the southbridge (ICH5R). As far as a recommendation, go for the E model. Gigabyte lan may not have much use now, but in the future it will. Kingston's Hyper-X mem is a good choice. Corsair's XMS Pro series (the modules with the activity LED's) is also a good choice. Just about any PC3200 or better will suit your needs. If your going to overclock (you might not have enough headroom with the 2.8 though) you might want to concider Abit's IC7-MAX3 mobo. I have one, and I love it!
