New Hardware

Well ive been looking @ some new Hardware, Apple Wireless Might Mouse. @ 125$NZD, this mouse looks nice, and is wireless. I wish the Apple Keyboard (with number pad) was wireless. Anyway been looking @ this, what blue-tooth device is needed to get it running on my Snow Leopard. By the Looks of things it will work, but not the Feature to turn on your computer while its in sleep mode.. But im not too concerned about this, cause my computer is on 24/7. The other option is Quad Core.. Intel Q8400, or Q9400 both are the same speeds but with the Q8400 having 2mb less cache then the Q9400, and cost is about 50$ cheaper. But i am getting a New Case, dont know when... LIAN-LI PC-A05NB
