ok, so recently i got my Ubuntu cd's and one of them happens to be a version that will run on mac, so i looked on ebay, and i can get alot of good imac's for cheap (under or just over 100 bucks), i was hoping to get atleast a 400mhz, with 128 or 256 ram, and have a dual boot with whatever mac it comes with, and my ubuntu... is this possiblie? i have never heard of a dual boot on a mac, but then again i havnt heard much of anything about macs...
