So my question now is which is the better option of hardware that is reliable enough with less maintenance and problems.

Then that would be the Avalons. Over the past few years I've ran several dozen of them from A721's on up to the latest: Zero major problems and just 3 dead fans. Frankly I doubt any other make is more reliable.

Thank you for the information.

Well, if I'm to choose from A841, A851, and A852.
Which one should I get?

Specially I can't find deep information about the A852.

Only one I would say to avoid is their A921 series and that is just because the 841's can be made to be just as efficient in power/hash rate. It also uses a larger fan that can be rather hard to find a replacement for.

But if I found some cheap ones which has less $/TH price. Would I buy them? Let's say I found A852 for $200 that's around 13.33$ per TH, and I found A921 for $240 which will be valued @ $12/TH.
Is it worth it to save more with the A921 and deal with the maintenance or no?
