Thanks guys,

That is the answer I was expecting but not the one I wanted, it does make sense given that the S5 kicks out enough heat that my lounge is a toasty 21c without heating. I was hoping that if I left the back door on the cab open it would keep the temps low enough that I could run it on a temporary basis until the rack is moved to its new location in a temperature controlled server room generally kept at 18 - 21c @ 30% - 36% RH

@Jamphone I am interested if you could elaborate your response regarding it not paying for itself.

My work is allowing me to host this unit FOC in my test environment where all costs are covered (Power & Data) so my only cost is roughly £1600 for the hardware itself. Given that my current setup (roughly 1.3th\s is yielding me 0.1 BTC per week) adding a SP35 should yield me roughly 0.5BTC per week. I have to give my manager 2BTC for hosting (up front fee not a re occurring cost).

So providing that it keeps making BTCs for me i will return a profit eventually; especially if the BTC price jumps in price to some silly price again then all will be well.

The only way I can see myself not making money off this is if it needs to be hosted in our T3 Datacenter which comes with a £450PCM fee + Electricity, or if the BTC price tanks and never recovers.

NOTE: I am not rubbishing your response all input is very valuable to me but I am struggling to get past all of the people who say " you will never profit/break even mining is a waste of electricity. the difficulty is too hard" I would like a balanced argument on both sides.

Thank you again for your input.
