For those of you wondering about the Stakebox mentioned, I got hold of the guy who designed it about a couple questions regarding upgrades and memory capabilities.
The StakeBox is based off of the Raspberry Pi 2, it has 1GB of RAM. I am looking at other, more capable, devices for an upgraded version of the StakeBox. As far as updating wallets, I just finished setting up simple, one click updating of wallets through the web interface. I need to get that info up on the website today. If you have any other questions feel free to ask, thanks.
I have this one and works great. You don't need anything more, it's complete as it is. I'm running 4 crypto wallets, one of them as a node and a complete web server. Normally it's consuming between 1.8 and 3 watts.
I've installed team viewer and I am controlling it through my desktop computer as if I was working directly on it.
It's a very good, complete and cheap solution. Ainol is well know by the desing of it's mini pc which keeps the temperature of the processor pretty cool
