if this were me there'd be blood. I really need to start taking pictures of my 'projects' because no matter how miniscule they are blood is spilt. Just today I was sleeving some molex cables and I split my thumb open. Didn't know what to do so I melted some shrink wrap over it and so far it's holding up pretty well.
On topic, I really hope you get the PS3 working. I for one think watercooling the PS3 isn't a bad idea considering it seems like a somewhat preventative measure to secure the PS3 from messing up. Not to mention a cooler PS3 can even run games better in my experience. Not significantly of course but only run it as well as it should run, just without it getting worse. When I broke open my phatty before I got rid of it all I did was secure some wires and it fixed my YLOD.
