Spring Cleaning your system, how long does it take?

I’m curious, how often do my fellow hobbyists undertake a “spring cleaning” of their systems, and how long does it take to complete?

I recently disassembled my entire system for some thorough cleaning; removing all cables, moving all components off the racks, dusting/cleaning all shelves and components, and re-running speaker and subwoofer cables, in addition to a good dusting of the room itself. This endeavor took me several hours, spread over 3 days. Not to mention the total weight of all the equipment I had to move around (several hundred pounds).

Looking around at all the cables and components laid out across the floor, I was reminded of how complex my system is, and how intimidating this hobby can appear to be. I know firsthand that a good sounding stereo system can be achieved without this much intricacy, for me though, assembling is part of the fun. It’s the destination and the journey that I find fulfilling.
