My SF2 cabinet was way too heavy to move from downstairs to upstairs without risk of breaking bones and floors... luckily, my particular machine was already somewhat modular... see the attached pic to see what it looks like...
I was able to crawl in and unscrew the top half from the bottom half, and bring it up in 3 pieces (Went ahead and pulled out the monitor to be safe).
I put it back together minus just a few of the screws in case I need to move it again, but if you have the option and can find a cabinet like this one, they aren't too terribly hard to break down...
