So I haven't ever owned an Xbox360. I bought a PS3 a little after it's release and it's served me well. I also have a decent PC, and seeing as most of MS games have been released on that, I haven't really needed one. A few gems like Alan Wake, Shadow Complex, Gears of War, etc made me think twice every time I passed one in store, but I resisted.
But as of 20 minutes ago I have a free Xbox 360! Here is how I went about it.
Step 1: Get free 3ROD Xbox 360 from my sister. (Out of warranty, so she just bought a new one)
Step 2: Open console up and apply thermal paste
Step 3: Wrap four pairs of pennys/5 cent pieces in electrical tape and stick them on the motherboard chips
Step 4: Hail to the king, baby.
Just in time for Halo Reach :)
I have a lot of experience in building my own computers, but I'd never opened up a console before. It was heaps of fun! I totally didn't expect to get it working, but I'm happy I did. If you've ever made your own computer, fixing your xbox is a total cakewalk.
Anyway, I just wanted to share my efforts ^__^
I'll post once I get a gametag and shiz in case anyone from Aus wants to add me.
