I got a ghz TiBook when they came out last November. It was my first Mac ever, after being a PC user all my life. I am like a school girl I am so happy with my Powerbook and the Mac way of doing things. The thing is, I can't stand using my PC anymore, and I want a Powermac now. I just have a few questions though, as I still don't know all there is to know about Apple's ways. 1. If I order a dual 1.25 machine, can I just buy my own DDR ram from crucial or something and upgrade my machine when funds permit? 2. Can I use my 19" flat screen CRT monitor with the Powermac? Or do I have to have one of the apple displays? (I will eventually get an Apple 23" display, also when funds permit) Thanks in advance!!
