What cost am I looking at to go liquid cooled?

It looks like the parts are custom machined and it's about $100 bux for the plate for my GTX 780. The pump, the plate for the CPU, tubing. Also, I understand there is cooling for the chokes/capacitors and the MOSFET. New to cooling so I am trying to get a realistic understand of the costs of this.

If you're looking to run a custom water loop; expect anywhere from $350-$400+. Custom water loops aren't cheap by any means, but they do the best job of cooling when done correctly.

My own personal opinion on the matter is that custom water loops are only truly worth it if you plan on cooling more than just the processor. They're far too expensive and time consuming to install when you can easily buy a CPU only closed loop cooler from any number of vendors.
