I think the i7 is great and cant wait to see what you have next, although I wonder why you created the i3. The i5 is a good alternative to the i7 though. I always have at least 4GB RAM and I dont worry too much about the speed as long as it doesn't bottleneck the PC and as long as its not a rip-off.

I like to have lots of USB ports and at least 2 DVD drives. I like a good quality, long lasting motherboard with at least 4 PCI slots and a PCI-E, or, more preferably, 3 PCI and 2 PCI-E slots.
