I want to build a proper server with room for 40+ HDDs to move my media server to and have RAID 1. I know a lot about PCs and software, but when it comes to server hardware I have no clue what I'm doing. How would I go about building a server that has access to 40+ RAID 1'd HDDs?
The data is currently stored on external drives, but once I've got the new setup with RAID I'll erase the drives and sell to friends, or use in other projects like an emulation station. 15+ wall plugs is excessive.
