Just got a dead G5 (2.0 DP) off my local market, the case is polluted by chemicals(I believe it's used in a factory before it died). It comes without any memory, hard drive screws, air deflector or PRAM battery. First thing that I do is to reset PMU while unplugged. It didn't work afterwards then I try again while plugged in and it turned on with no chime (power led blinks quickly). I noticed that I forgot to install the memory, I salvaged one 512 MB and one 1024 MB DIMM off my old PC, installed it and still not booting.
