Multiple Pi Server

After a major server crash of my web and e-mail server I decided to make a Multiple PI Server. One reason is to save some energy though still using my own physical server(s). The second reason was to learn more about the different flavors of low costs mini computers.

The following parts are used:
– small power supply and a print board to extract the 5 volt supply
– Raspberry PI as webserver for, with SSD via USB
– Orange Pi as backup server, with SSD via USB
– Banana Pi with build in SATA support for email server, SSD via SATA (not included yet in photo)
– a 5 port ethernet switch
