I am sorry I cant help at that price range buddy...
200 USD is to be blunt and please dont get offended... You will not get anything high end at that price...
For speakers alone I would say a 1000 USD as a minimum just for the speakers, and on top of that you need an amp to run them. Pluss you need cables.
And now we are at an entery level high end build with this setup:
Speakers: Monitor Audio Silver 200
Amp: Rotel RA-1592
So to be honest if I was on a budget with 200 USD I would just go and get headphones. Alot more sound pr. dollar than getting a full stereo build...
On a side note, if you have not been to a shop and listen to or owned an high end system before you could just try and get a regular stereo setup for the computer...
