The hardware design of the vault is open! The vaults are running Backblaze v6.0 Storage Pods (https://www.backblaze.com/blog/open-source-data-storage-serv...) and the nice thing is, you can use whatever software you want to run them (we likely won't release the software, but we have talked about parts of it like Reed-Solomon Erasure Coding https://www.backblaze.com/blog/reed-solomon/).

As for getting the servers, there's an entire company that popped up from one of our early storage pod producers, Protocase, you can buy servers (very reasonably priced btw) based on our designs here -> http://www.45drives.com/.
