Here is my FileStore E20. It is light grey in colour and the same design as the FileStore E01. The drive door is missing from this FileStore. It is not critical in an E20, however, because there is no drive door sensor like in the E01. Ironically, my FileStore E01 has a replacement drive door which is from an E20! It could be the same one!

I used to think my FileStore E01 was noisy until I got this! It is about ten times noisier! When I got it, the fan was disconnected from the PSU - now I know why! I have reconnected it, however, because the power supply does get quite hot. My Technomatic Winchester and Teletext Adapter live on top so I do not want things getting too warm.
