I suppose I've already fulfilled my list:

1x Bandai Macross kit
1x PC game (Fallout 3)
1x Painting supplies (compressor, airbrush, paints, thinner.........)

All with my own money, but that's how I get Xmas presents since I've started working.

May consider:

New wallet (I need this actually)
1-2 PC games (Dead Space, maybe Left4Dead)
2 more model kits (Patlabor & N.G. Eva) (Maybe later on in the year)
New PC case, a really quiet one, preferably with an easily cleanable front filter (my room's attracts a lot of dust)
