The Power Computing Power Tower Pro 225 I have laying around is in need of some more memory. When I opened the case on an unrelated project, I noticed that there are 8 slots for the memory with a total of 4 sticks of RAM in there, but they are in pairs. According to MacTracker, I need 168 pin FPM DIMM memory, but I really don't know about these older things. Are there certain websites I should look at, certain computers that I can salvage the RAM from, or what?
