One of my clients sent me a pic of his mine.  All of the rigs are mounted in my mining trays (with tops).  

The GPUs are all 7950 Radeons (mostly MSI Twin Frozrs).   Max hash is currently at around 73MH.



Box fan cooling FTW!   Grin

I think that standing air condition helps... Just a smidge. Wink


are those 4 7950s each to make 80 cards in total? IF so you're avg 912 ish MH per card:

A) how did you do that?
B) how much was the cost of the entire Setup including COOLING
C) how long ago was this built?  I put the general presumption of 1200 W psu and 24000 Watts constantly from those 20 satellite machines.  That is a 57 dollar a day power bill WOW.

[My calculations put it at just under 26K such that:
(HD,Mem,Processor@ $90 1200W PSU @ $179 4 7950s@$900 Mobo@$90 Misc Cost@$5+ Structure,AC,Monitors, Network Components @$20 per machine approximately)*20 units]

Using coinwarz the median number seems to be around 340 dollars per day if you were to cancel out the crazy outlier days, I see ROI in Approximately 77 Days so...WOW!



I see 5 cards per machine, so around 100 in total + maybe a little bit more at the end there.

You're right its hidden due to the edge of the border.  I like spotswood cases by the way have one myself.  

Ok so the new numbers changed a bit - I replaced 900 with 1250 to approximate 250 per card with 5 per rig at 22 rigs = $35948 / ~$340 now equates to 106 days till PURE profit

It is sooo much fun dreaming about this - so I looked at the square footage of our work facility - we hypothesize that 90 of these racks could be fitted on our premesis - that brings in about 30K a day, and costs approximately 3.1 Million (didn't calculate power costs to see if they scale as I don't know how much extra his cooling costs add onto so I would venture a safe guess of 5000 base cost plus 4000 additional for cooling cost DAILY!  Still though 3.1 Million/ 21K  = 108 Days until PURE profit!  Ridiculously PURE profit!  You too can have a million dollar month each month Cheesy

That is really neat for that much of rig....
