Busted light switch

Ok so in an attempt to allow my cm 690 II's light switch to affect my UV LED, I decided to solder and crimp some molex cables together with some supplies I got from moddiy.com

Ok so after removing and desoldering the initial connection I was fine.  Soldering the new connection was a PITA big time..  Reading and watching instructions and then trying to replicate it did not work.  The wire I was using wasn't heating up high enough for the tin to melt onto the connection.  I ended up having to melt the tin and try to manipulate this blob as it fell onto the connection I was trying to make.  Anybody who has soldered before will know that this is pretty much fail.

Anyway after a good 40 minutes I manage to get a decent connection that I was happy with.  I then shrunk the heatshrink and it looked great!  I couldn't be more pleased with how my first efforts looked.  Then I tested it.  SUCCESS!  The UV would now turn on and off at the click of the switch.  At this point I was feeling pretty good about myself.  I decided to try and plug the original fan light that the switch was meant for.  I felt a sudden jolt through my body and heard a zap bang at my fingertips. The cable fried.  It set on fire and I gave myself a mild electric shock.  Had I not been wearing my Havaianas it could've been much worse.

After I got the image of an actual fire inside my computer out of my head, I proceeded to place the switch back in its original slot.  Here is where shit starts to happen.  So the cable was too short to have the molex heads hang behind the motherboard tray.  OK no biggie I'll use a molex extension.  So I get it in there, and as I'm trying to get the top to close, I see the ground cable I crimped come loose.  F*CK....  At this point I'm already pretty over it.  I pull it out to attempt a recrimp.  I hear a little snap as I pull it but thought nothing of it yet.  As I sit down and prepare to fix the loose cable end, I see the little pin that I soldered the wire onto fall off.  That was the snap, and that was the end of my first endeavor into cable making.  The switch is now dead.  Until I can find a replacement, my lights will remain always on.  I may just switch to white LEDs.  Ah well.

Also I'm fine.  Just a little burn on my finger but apart from that I think the fear of seeing flames ignite inside my case was the most I suffered from this ordeal.

Here's hoping for a smooth installation when the Extreme11 arrives!
