So today I came across a listing for a Quad G5 for $90 with no HDD and 6 GB RAM. I have wanted a Quad for a long time now, and found this one, which is in my price range. The listing says that the computer won't turn on, but the power button LED comes on when the button is pressed. I have looked around on Google, and there are articles that say the PRAM battery is bad, the graphics card is bad, or the RAM is paired incorrectly. I just want to ask before I purchase it because I don't want to blow $100+ on a new logic board/processor. Really hoping that it's simple because I want a Quad so badly!
