How much should I sell this for?

[Envy__]

I was wondering how much I should all this sell this for, everything in on the parts list and all is compatible even if it's worrying about the Coolermaster. Also I know these prices are new, the pc itself is a few months old so take that into account. Feel free to say what I should sell and keep/ whats worth it and whats not.

Everything together? Maybe about $500. Probably better off selling the PC with just the basic mouse and keyboard, and then sell the fancy mouse/keyboard/headset separately. $500 tops for the PC and then whatever for the rest.
