The R4's are prone to board failure as you have already found out. I think the R4 was targeted at the average consumer that wanted to mine a few hours a day... those machines really were not made to run 24/7 and when they are... damage occurs.

L3's are great but now you are getting into some more expensive machines... not even close to an R4.

Either way, build a dedicated room if you are going to mine in your house... keep the dust out and most importantly... get rid of the heat!!

Thank you.

Given the (lack of) availability for the Bitmain products, I'm planning on purchasing 2 or 3 Avalon 741s.

Using the CryptoCompare calculator for three 741s, I have a total of 21.9 TH/s, 3450 Watts, and a power cost of .10 kWh. It says I'm looking at $20/day return (~$600/mo). I'm fine with that return, but is that actually realistic? Seems too good to be true.

After the miners, PSUs, and other odds and ends, I'm looking at around $3000 initial investment, with a 5 month ROI (all else remaining constant).

Any advice?
