hi ripper...congrats mate!
no no machan dont DIY...the 360 is very delicate as it is...there are some shops who do that for you but i think it'll cost about 10k..pm me if you need the particulars
and machng it may not be a bad idea to purchase a cooling fan through ebay for the 360....i trust you did your research about the red ring of death eh.....
modding the machine may aggrevate the red ring of death problem.....and modded machines can never play online because you get banned from XBOX LIVE.....trust me online gaming is superfun,it actually doubles the value of the console.....bummer you couldnt join mani and me cos we're both playstation folk
some game reccomendations for the 360.....HALO 3(duh'),GTA 4,Forca 3,GRID,Colin Mcrae:dirt,assassins creed,bio hazard 2...
happy gaming dude!
