Can I put PC ram in my Mac? Or will that tear a hole in the universe? Since I am having trouble finding somewhat-reasonably priced PC3200 ram that is specially designed for Macs (in my case a non-iSight iMac G5), I was wondering if I could put, say, HP brand PC3200 ram in my iMac. Here's a link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=110340326488 Any advice is appreciated. Thanks!
