Ill be buying only because the machines I have at home are dedicated to other things. I could use my desktop PC but its a huge power waster, its klunkly and old and makes a terrible loud noise when it's on. In fact if anyone wants it for spares and is in Melbourne, PM me its yours lol.
Cost I dont see being a huge problem as I see it as an investment into a few things and farming/safecoin is only one of them the other is in my own education and learning how to out this sort of stuff together as i'm super interested in Raspberry Pi's, hardware and coding but just dont know that much about it all.
In terms of the spare laptops, they are a great idea. Thats what I used when I was mining some other crypto currencies until I fried them, lol.
The only issue might be in the amount of vaults they let you have. I think it is 1 per node and I am pretty sure they said they had a limit on vaults or something like that?
Also having two or more running nodes I believe would be more beneficial for various reasons.
In terms of leaving it on, it most definitely has to be on and running, you should be able to change your settings in your OS to run programs but sleep the screen or at least shut it so your not wasting valuable energy.
Thats awesome! I am going that way too only its super expensive here where I am but I see that as an investment and then I can buy a electric car and store my energy in that too !!!
Im worried about this too. I'm with Telstra and lately my Internet goes down at least several times each week. Its super weird. It just drops out for a few seconds or minutes. I think it has to do with the NBN build but ill be super pissed if that effects my farms rank...
Welcome! Pretty much what the others said. I am not that technical but from what I have read it looks like what will work for gaming will work really well here obviously minus sound, video but plus storage and then take that idea and replicate across more nodes.
