Just built sweet gaming computer... having to sell it for college :( need advice

[iasus]

I just found out I'm gonna have to take a few classes over summer since I'm doing my internship next semester. The shitty part is that financial aid doesn't cover summer classes and they're 300bucks a credit hour($900 a class). So I'm selling my computer I just built. here are the specs. It cost me $1300 to build it 2 months ago. I'm curious if anyone has done this before and what the best way(craigslist, ebay, etc) to sell it is and at what price. It's in perfect condition and barely used. Also, if anyone on here is interested in buying it... we can discuss that in private chat.
Thanks for any advice!
