Bitmain Antminer S7 Bitcoin/Cash Miner 4.86THs -Can Run 5Ths+ Like a S9 or A3 #1

Description

*This is one of my very last S7 units for sale!!! This is a 4.86Ths with tons of potential for more!! They are going quick!
*
Up for sale here is one used Bitmain Antminer S7 4.86Ths mining machine in
excellent working condition and overclockable
(the last picture is to show I have many of these). It can do 5Ths+ easily as long as you have good airflow.
There will be a small amount of dust in the unit as there is in all used units. I gave it a spray out with compressed air but it won't be perfectly clean as it is used.
This unit works great as it is but you can also do all kinds of tuning to make it hash much more efficiently than stock. You can also make it silent (or really quiet) by tuning it down a lot for a much lower power draw at a small hash rate loss. These tuning programs have come a long way since this was turned on last. I don't have the time to tune every unit I'm selling just as I don't have the time to thoroughly clean every unit I'm selling otherwise I would.
Given the current situation with the mining difficulty dropping so much it's a great time to get your hash rates up. Despite the current temporary drop in price the upcoming massive drops in difficulty are looking to make up for it. It's still a good time to be a miner thanks to China shutting down so many mines coming up soon as well.
*I will be plugging it in one time before shipping for just a few min to make sure it runs perfect so I know I am sending you a good S7. I will only accept returns within 24 hours if it is dead on arrival so please test the S7 as soon as you receive it. I will be recording the serial numbers to make sure any return is the same item I sent.*
*** Please do not bid if you have zero or negative feedback. Please also only bid if you have the funds available right away. I ask payment be sent at the time the auction ends, within 24 hours at the absolute latest. I can't ship your item until I get paid. Thanks for looking and happy bidding!***
