i was talking about modding a mac, not upgrading it. by modding i mean modifying the case, with a window, extra fans, etc. upgrading a mac is a pain in the ass... but with newer intel macs it shouldn't be that hard to get a CPU upgrade anymore. of course an equivalent windows machine will always be cheaper than a mac (and is compatible with waaaaay more software), so i kinda fail to see the point of buying one; but if you have one you can make it look nice.
