Hi guys! A time ago I saw a site which sold updates to older macs (yes, also to new ones, but mostly old). It sold stuff like processor upgrades to PPC macs, HDDs, RAMs, etc. Among all things it was a good reference guide what you can put in which model. Do you guys know of such a site? I don't remember the URL, and can't find it on Google - it's probably too many pages away. Can you help me out? Thanks.
