I ordered one last night just for the heck of it.. because my one friend was into ordering one.. so I said order one for me also.

Total was 1.3722  BTC for everything* incl accessories... if you do the math its almost exactly the same as 2x S3+ at current pricing when you take shipping into account.

I'm planning on using a .999 Silver Kill Coil ($6.99) and DI Water.

I built a liquid cooled PC years ago, and I swore NEVER AGAIN.. just too much of a pain in the ass to maintain.  Oh well..

*I reimbursed friend for the order in 100% BTC even though the accessories were paid via a different method by him.
