the s21 is not worth the extra money than the t21 in almost every case.


model s21          t21
hash   200th vs 190th
price   3780  vs 3059.    you save 710 usd the mode is about 210 so you save about 500 bucks.
watts. 3700  vs 3700


the t21 ships faster

10 th earns 50 cents a day.  so it takes 1000 days to make up the 500 extra for the s21

and I am not counting that you can sell the psu that you pull out for 250-450 on ebay

plus the power cord https://www.ebay.com/itm/186397914642?



So if you get 300 for the oem psu and the power cord you were paid to do the mod

this mean you save 800 on the t21 not 500 at 5 a day that is 1600 days before the s21 goes past the t21

So I kind of feel sorry for people that did not go for t21's and mod them like I did.



Now if you read all that I said I was pissed to start when I found out I need to mod my gear but I ended up making out better with the t21's

I think any hands on person should consider the t21 as pretty much an equal to the s21
