There are those that would tell you that 2 steering and 2 fixed is good for large-ish, heavy-ish rolling devices. Let's just say that I heartily disagree, from experience, and suggest 4 casters, all locking. You may need a second person either pulling or pushing, but it'll be a lot easier to manage in a tight space, say the pit aisles or the classroom, if you have the ability to go side to side. And if they're all locking, trying to move the cart will be made very difficult, even if you can't get to one or two to lock them.

Make sure you can go over a large cable protector in any case--figure about 2-3 inches vertical and about the same or maybe a little longer horizontal.
