lol... gona need more info than that dude. Do you want something that will hook up to your computer via 1/8" mini plugs? Do you need surround sound? Or is 2.1 fine?
Do you want speakers that will just hook directly to your PC or do you want an amp and preamp, or a reciever?
As above, i didnt have the space and didnt really need 5.1 so i went for some Logitech z230's(2.1) and they sound amazing, very good bass aswell, and it was pretty cheap brand new!
