start with a shinza notebook sleeve, then buy a nice case. Wireless mice and keyboards are always great. A notebook cooler wouldn't hurt if you want the bundled USB hub for functionality as well. There are so many things you can blow your money on it's not even funny.
grado sr1 headphones (best head phones money can buy)
audigy nx 2 (for gaming sound card)
indigo echo (for true audiophile listening)
microsoft bluetooth mouse w/ bluetooth dongle
logitech mx510 blue colored mouse as a precision gaming mouse
shinza notebook sleeve (best laptop skin imho)
I could always use some extra dough. Then i don't have to actually paint the damn laptop. And get bragging rights. Voodoo, Falcon, Alienware if they update their line ever, Hypersonic-pc here i come. That would rock.
