Okay. I recently got a G5 with a fried power supply (caused by leaking LCS) and to my surprise the CPU was pretty much untouched! (just a little contaminate on the tops of 3 of those little capacitor thingies. (not entirely sure what they do, but I'm 95% sure nothing bridged) Will I need to replace the tubing on it (It seems to have leaked out the O-ring) and what coolant shall I use as a replacement? I already have some Arctic silver 5 for when I rebuild everything and I've got some alcohol in the post. Finally, How do I actually drain the unit and refill it?
