I have a Dual Processor 2.5Ghz G5. Today while cleaning out the vents and fans I had laid the machine on it's side for a brief moment to wipe down the underside upon lifting the machine up from it's side I had noticed a few drops of clear blue like liquid on the table. However upon checking the machine thoroughly both inside and out I cannot find where this liquid might have leaked from. I am pretty darn certain that this is from the computer. The liquid looked like some form of coolant and had a bitter taste to it (yes I tasted it). Upon smearing the liquid it had a slightly greasy feel to it. Hmmm.... Has anyone else noticed liquid from their G5? I assume it's safe to lay the G5 on it's side since that is what the Manual says to do when installing RAM and PCI cards. I have since plugged the machine back in upon realizing that everything was dry or at least what I could see. I am currently running Temperature Monitor and all temps seems to be within normal operating conditions. I am very concerned though and will be calling Apple Care as One drop of liquid is one drop to many. My fear is that liquid coolant might get on the Power Supply or somewhere else. I am very very nervous right now. Must shut down computer before something bad happens. I remember being paranoid when I bought this machine a year ago thinking about complications with the liquid cooling system and worst case scenarios, However after much assurances from Apple Store Employees and even people on this website I was assured that the liquid cooling system was reliable and maintenance free. And now this!!!
