(I'm also buying a nice popcorn machine for when I watch films).
PS3:
Ikea TV cabinet (It's pretty beast, and cost me a lot of money lol).
32" LG 1080p TV
2x Turtle Beach P11's
4x PS3 controllers (buying an MLG Pro controller next week).
Playstation Move
XRocker gaming chair (trying to sell this)
and of course, my PS3 & games..
Oh and I do have a blu-ray player but that's for downstairs. I kind of bought it for my mum, but it's still technically mine if that makes sense. (A temporary gift you might call it, although I'll probably let her keep it when I move out).
I'm actually decorating my room (with my PS3 set-up) sometime in the next month, so once it's finished I'll throw a pic up. It's pretty nice I think, just looks a mess at the moment because my room is a tip.
I just wish I had enough space in my house for my PC set-up as it's a little frustrating having to go around to my grans house to use it. Would be amazing if I had a gaming room with my PS3 and PC set-up next to each other.
