What are the specs of the box?

If you REALLY want to go pro with staking, I HIGHLY recommend looking at Odroid U3 with an eMMC card. Those little puppies will run many wallets no problem and are practically set and forget if you are just looking to stake and compound. If you are patient, the odroid C1 is super sexy as well, but they are hard to come by right now and you have to preorder one if you can wait. Even if the U3 or C1 might be over kill, low power arm boards are definitely the way to go for PoS.
