GODDAMNIT DONT SPEND IT ALL IN ONE PLACE!!!!
I like macs, macs are good macs are your friend. I'd suggest getting a mac and digital performer with a motu interface. But really pc's are nice and cheap, and theres good hip hop making software for them about, so get whatever depending on the software your going to use.
Pro tools is basically a mac deal. Their expensive systems are a mac deal though there is the windows nt version wich kind of flopped. Id suggest if you had $50,000 to get the full blow pro tools, but with $10,000 Id say most definately do not get it(for real). What good would it be without all those other essential elements?
What you need to do is get a few quite nice microphones, some really quite nice moniters, some not to shabby a/d/a, some abolutely sporting pre amps, a nice lexicon reverb, a few rack spaces of eq and compression, a collection of plug ins such as the waves native gold bundle, a decent array of synths(rompler, virtual analog and sampler) and a control serfice.
If you buy the $10,000 system youll have blow your wad. You must budget to take into consideration all the factors I laid out. If you dont spend your money wisely Im going to morph into binary code and traverse the internet to arise from your computer and kick your ass(nothing personal).
Also, dont listen to anything these guys tell you here. There are a few knowledgable guys that you should really listen to but most of us are jerk off's.
What I'd suggest is going to more professional forum and saying "i have $10,000 help me budget my daw" or else stick around so you can surmise whos full of shit.
And before you pay the piper dont think twice THINK THRICE!
