I have been a PC user all of my life and know zero about macs and always called them "gay" or "crap" so i decided to stop being ignorant and actually get one and learn a little about them and osx. i just won this bid on ebay for a blueberry APPLE iMAC G3 400MHZ 128RAM. It has a slot loading dvd. i just had some general questions can anyone tell me the model or specs? is it a imac dv? what kind of video card should it have? can i upgrade the video card or video memory or RAM? can i use a microsoft broadband router to connect it to the internet? (not a joke) can it play dvds smoothly? do i need software to play dvds? can i run opengl?
