NOOOOO!!!!
If you're keeping the cab, store the parts in there to keep 'em out of the way. If there's one thing I've learned, it's that if the parts are on hand, I'm more likely to get inspired to do some work on my cab. Maybe you'll have inspiration a week from now. Don't want to be left empty handed.
Look, I'm still working on my first cabinet, but after a lot of false starts I'm seeing some real progress. And I started lurking on this board two years ago or more.
Hang on to it!
