Looking to water cool my CPU and GPU

From what I can see the Corsair 500R doesn't even have the ability to install a 240 rad on top (excluding modding). Only half size rads will work and it's not really worth it then.
I would advise a cheaper kit so that you have money left to buy the CM emmediatly. From this picture it seems the CM can fit an RS360.

That allows you to buy an XSPC Raystorm 750 RS360 kit which is around $160. The kit comes with everything you need except fluid.
edit: Do you also want to wc the gpu's? I see the topic title says so but you don't mention it in the OP.
For the gpu's you can get the kit and add 2 full cover blocks for the 680's. A 360 sized rad will become limited to cool a cpu and 2x 680 tho. It depends how much you want to overclock it, your ambient temperatures and if you don't mind non-silent fans.
You'll need 2 full cover blocks and connect them either with a bridge connector or add a tube between them.
Watercool and aquacomputer are very liked manufacturers. But I don't know how easy those are to get in the US. EK and Koolance you'll find easily.
If you want to cool high overclocked cpu+2x gpu and use thick rads for silent fans and redundant pumps, I don't think it's possible with $500. It will certainly be very challenging to do in midi tower cases.
Maybe there is a low cost build magician who can jump in with a bit more knowledge of the cheapest stores in the USA.
