I attach to inanimate objects and grieve with change. In terms of computers, I hold onto old hard drives for years (need I say decades) before I get rid of them and that is only after moving all files (even system files) to a new stored location.

On a slightly different topic, I have found hoarding ebooks and audiobooks has been a way to feed one element of my needs without cluttering my physical space with stuff. I have well over 5 TB of audio and ebooks.
