If you count an old hard drive I’ve always had that going, easiest to use your old app drives any reinstalls may go more quickly plus any media files on there. Though my media is mostly on my NAS, pictures tend to be on a local drive. I’m not sure I’ve ever done a new computer without an old drive and I’ve been doing this for like 25 years. Though I tend to move the old files to a newer drive before the next upgrade so not a true ship of thesus. Though most times the GPU upgrade is done at different times than the CPU/mobo/ram to keep it cheaper.
