Hi, I have a few suggestions for you.
Currently I'm using a Wood Technology LP/laserdisc Base Module for my laserdiscs. It's cube shaped. The Wood Technology line includes stackable drawer and component modules. All require assembly, and they can be placed in any order. Castors can be placed on any of their units. I bought mine through Crutchfield. For a look at their stuff go here:

My father owns 3 VHS cabinet units from Lorentz Design. They also make a unit for LPs and laserdiscs. All their units come fully assembled and have a higher fit and finish than the Wood Tech stuff, but aren't stackable. These also can be purchased with separate castor bases.

Another racking system my father uses for storing his VHS tapes is made by Boltz. All their products are made of very heavy gauge steel and are made to be leaned against or attached to walls. I use these also at work for storing CDs and DVDs. They recently introduced a line of steel furniture that includes TV units, component racks, and shelving that can support LPs. If you're curious about their materials, they'll send you free samples that make great paper weights. For a look at their stuff go here:

Billy Bags also makes a small rack [by their standards] for storing LPs. Take a look here:

All the companies mentioned above make great racks. These days I'm in the process of building a wall system to fit my specific needs. Good luck with your search!
