ASICS usually are built to run 24/7 so your fine. Even a PC can run 24/7 but its all about keeping tabs on those temps...gets too hot you gotta give them some cool down periods to avoid wear.
Not sure what box you mean, did it come with a raspberry pi controlller maybe?
nice.
yeah thats what it is...

found some info here... ill read up on it.
That looks to be a controller maybe, not sure because I haven't used their miners before but probably what stores the software to run it, thats my guess though lol....every model is different. But that is a great one to mine with, wish I could afford one lol
