WTB Neptune Cube(s) or board(s) I have controllers

[sobe-it]

I bought a lot off ebay and I ended up with 3 KNC controllers. I have no idea if they even work so I am looking to purchase a cube/board that is known to hash (or maybe more than 1 if the deal is right). I don't care if it/they are 1/4, 1/2, 3/4 or 100% working. I have heat sinks off a Jupiter if all you have is a bare board. I have only have paypal at the moment or could make a deal with some of my s3s or s5s. Possibly if all 3 controllers work we can work a trade for 1 of them. I know talking about paypal here is like talking about Voldemort but take a look at my trust.

I know these things are hit or miss but I don't want good controllers collecting dust and it would be nice to know if I could potentially buy a titan cube down the road.
