Alot to consider. If the cabinets aren't efficient, get them out. Especially if things are cluttered and you need to be more efficient. At the end of the day, regardless of how things look, an organized shop is what will bring the biggest smile to your face.

If you want to do a bunch of work for a night and day difference, break your ass prepping that floor and put down some epoxy. If you spruce and paint around a new floor, it will look like a brand new, modern space.
