Lol, thanks for the replies, everyone. Haven't felt the need to put water on my system just yet, but I'll rest easy knowing it'll bead up if I do. Thanks for the demo, Krueger///M3!
But yeah, it took me a while to find a working 60gb PS3 in good condition. The internals of the system (from what I could see through the vents, anyway) were pretty much spotless. Not even dust in the vents. The only flaw with the system was the scratches on the shell, but I figured the internals were more important than the case. Now I just have a case shine to match.
