Hey Bruh,
It kinda depends on what exactly you wanna do really. Do you wanna record just music, or music and vocals? Then you need to be aware of your computer specs, that is the CPU (processor) speed, memory, hard drive speed and size. There are several avenues you can take with 2 grand. Then, since you mentioned a computer, I take it you are going this route, so let me know what's up with the specs on your computer and what you are going to use your studio for, and your familiarity with what brand of music software if any i.e.: Cakewalk, Cubase, Reason, etc.
Then I can give you some pointers, because i'm in the same boat as you with a budget to spend on a studio upgrade.
