I'd love more pics / info if possible on them. I'm interested in running a similar set up, though only starting with two miners and a single dps 1000w psu. What are you making around $15 a day? Only a couple months and they will pay for themselves!
Hello mate
They are hashing at 1950-2000GH using BTCGuild pool and the last 24 Hour Earnings according to BTC Guild is 0.02563142, which is about 9-10USD or 6GBP. Not sure if thats any good?
It's about the same using this calulater
https://alloscomp.com/bitcoin/calculatoryour profit after electric costs (on the miners alone) is currently ~£50 per month.
