No offense, but you jury rigged an already risky piece of hardware, used an over the counter below-spec fan with a smaller dia than factory ()factory fans work VERY well) and still want price close to a new S7 for example?
Good luck with your sale.
To address your points.
1) its jury rigged: I think that is an advantage as the original designers were frankly idiots. My Mod makes the Neptune safer and reduces the load on the connectors that were overloaded in the first place, and makes it possible to overclock. It no surprise that so many of the Neptunes burned the PCI-E connectors and the PSU´s. Its stood the test of time already with months on end of mining and no warm wires and other problems what so ever. I frankly do not see how that makes my Neptune less worth.
2) The Front Fans on the Cubes are for the most part original except for two of the cubes that had replacements, with same diameter fans but slightly higher CFM. The back fans are corsair 120mm high performance in a pull configuration, actually make the cubes colder as it provides better airflow. It only adds to the cooling capabilities, see the temperatures of my setup, cant say I have seen any other Neptune that runs so cool.
3) The S7 is currently 2.1 BTC without EU VAT(25% in my country), not talking about the noise it puts out, where as the Neptune is all most silent in comparison.
I do not see the negative points you are trying to make, instead what work I have done to make the Neptune better only adds to the Value not subtracts from it. The only way that the Neptune was considered risky was because of the sloppy original design and the careless safety measures the KNC designers took. It is like that they did not want the miners to last, hmm wonder why.
