Ok I have been borrowing a g3 500 for a while.. I dont want to screw it up by installing photoshop and things cause I have to give it back in 3 days., I am a PC user but I really like the mac so far and I decided to order a g3 500 and upgrade it, it comes with 1gb ram, 2 hard drives and dvd burner (my sig) I want to upgrade it with an 800mhz g4 zif, the b/w ships tomomrow morning. I was wondering how well this machine will run photoshop CS, I mainly work with 3.3mp jpg images. Will I be able to watch DVDs ? It comes with an ati rage 16mb video card that I want to upgrade to an ATI 9200. I would also like to know how tall the case is to see if it will fit in my shelf on my desk by my pc case. Will I be able to run a webserver on it great? What about iTunes? Im guessing it wont be that great for video encoding compared to my p4 1.6ghz PC.. Will this Mac be good for me for a while? I will mainly be using it for school. Thanks!
