Now this has useful features.

Just came across these guys. This server has features like a stripped down Linux Kernel so the OS is only 8MB. Also the OS is stored onboard so even in the event of massive HDD failure the server will still be up and running. Another feature is Intellegent Disk Backup which enables automatic backup to a HDD at a compression ratio of 2:1, so again in the event of HDD failure your able to get your backup up and running in 2min, although to fully decompress will take a few hours.
