Do you have a small office?
If feeling constrained is really cramping your office style, switching out closed-off storage for open shelves might help. Just like in the kitchen, open shelving in the office can create an airier feeling, as long as it's not overcrowded or cluttered.
Are you organized?
Open shelves mean there's nowhere to hide messes. If you're naturally organized--the kind of person whose cabinets would be spotless with or without doors--you'll do well with open shelves.
Do you work with lots of tools or references at once?
If you need instant access to lots of tools throughout the course of your work, open shelving can help. Without doors and compartments, you can see everything at a glance and grab what you need easily. It's like an expansion to your desktop space.
Do you actually use everything you store?
One of the biggest "cons" about open shelving is that you leave everything open to dust and dirt. But that's only a problem if you don't actively use most of what's on your shelf. If you've pared down your gear and only keep often-used items around, dust won't ever be a huge problem.
Is your work or hobby creative?
Professionals in creative industries are a more likely fit for open office shelving because they work with materials and tools that have inherent aesthetic qualities. Dull finance textbooks don't quite make the best backdrop for your workspace, but garments, jars of ribbon and colorful art supplies definitely do.
