So my PC that I built about six years ago is dieing and I don't want to spend the money on a new one. I have a G4 that I bought from the university surplus for $20, so I am just going to use that. However I have some questions before I make the switch: First, how much will a copy of OS 10.4 cost? When I bought the computer it didn't come with a hard drive or memory, so I am going to have to obtain a copy of 10.4 (I know 10.5 is comming out soon if it already hasn't, but I don;t know if my computer can run it. I think it is 450mhz and has ~256 of ram) I can reformat and use my IDE hard drives I have in my PC right?t? Also is it possible to get an IDE card and add extra hard drives like on my pc? Will 10.4 be able to read/write mt my NTFS hard drive that have all my movies and music stored on them? I want to avoid shuffling files around and I reformat everything. Can I use my bluetooth logictech keyboad/mouse with my G4? I really like them and I can't type worth crap on the keyboard that came with the G4 (old school iMac type keyboard) Can I still have my dual monitor setup on my Mac? Right now the G4 has some single output video card. Is it possible to use my ATI 9600 in the G4? Also, I have never used a Mac outside of school or work, so I have never bought Mac software. If my old and busted G4 can handle it, would it be worth it to just wait and get 10.5? I know most of the questions are really basic and I could probably find the answers with some time on google, but I am jsut looking for yes/no answers, and I can figure out the rest. Thanks for helping me out.
