Well I assume a lot of it would be taken by tax, so probably buy a top of the line PC to do me for a few years, then upgrade it as and when I could from that point onwards. Use whatever I had left to pay for me and my friends to go to Reading Festival this year, make sure I can go to Insomnia again as well, then have all of my year out being chilled as fuck going to stuff like Defqon 1 Australia, Qlimax, Exqlusive and other things like that.
I say this, but I'd ultimately end up wasting it on random shit.
