Hi all, a while ago I got a G4 and thought about upgrading it but didn't really have the time, now I do. *I want to upgrade this one, NOT buy a more modern, used tower* I will try to give you guys as much info as possible: I'm very much a beginner when it comes to modifying PC's/Macs but have some basic knowledge. I know there are tons of threads about this kind of thing but my eyes hurt from looking at the screen, I've spent days trying to research this but what one source says will/won't work, another 3 say the opposite! I am 99% I have the AGP version, 400MHz, 64MB SDRAM, 10GB HD, all stock. I WILL BE USING THIS FOR GENERAL PURPOSES AND WANT IT TO BE QUICK, HAVE A LOT OF STORAGE AND JUST GENERALLY BE BADASS. When I first got it, it booted up, now it doesn't, a mixture of 20 year old dust and crap just took its toll I think, I'm pretty sure it's the PSU thats blown, so I'm in the process of checking the voltage as per the G4 service manual, to determine this and will update as and when. These are the upgrades I want to make (with appx. specs and prices): 1) HDD - anything over 250GB (£40ish) 2) RAM - MAX 1.5GHz/2GHz (£30ish) 3) PSU - 500W (£20ish) 4) Processor - No idea on which one (£20ish) 5) Graphics - I've heard about Raedon 9800 and GF 7600? I've also heard about GF 6200?!?! Too many! (£20ish) 6) I will add an Airport card for wi-fi also. (£15ish) ALL PRICES ARE APPX. AND PRETTY MUCH WHAT I WOULD LIKE TO SPEND I think thats pretty much it, I will edit if I've missed anything, but what I need help with is determining what hardware to use for the job, and any modifications, or things that I should know that will make this impossible. I don't want to spend loads on this, I have resources but I want to do this for as little as possible. Any help/advice would be much appreciated THANKS!
