In my research for Storj, I was told that you can make a supercomputer from Raspberry pi for less than $3000 with 32 $35 raspberry pis. With some plexiglass and some cable, you can buy a SD chip and get massive storage for less than $3000 to have a raspberry pi super computer.
The college student who built it uses fans to hold it together. He said he doesn't need the fans. But he used them to make it look nice. It was better to be safe than sorry. You could use this computer to make a Storj storage unit if Storj becomes the next bitcoin. You could have hundreds of Terabytes. You could have tons of storage with Storj and make money if it became the next bitcoin.
If they need storage for Bitcoin, Storj was highly recommended. You could build a super computer for less than $3000 for all your storage needs.
