How To Store Record Collection?

Currently storing vinyl collection (1,700 albums) on Metro metal wire shelves. Looking for recommendations for bookcases, shelving systems, cubes, etc. Particularly interested if anyone has tried the Cubitec modular system? Trying to decide whether to go with off the shelf furniture or have built-in units constructed.

I've read that albums weight approximately 40lbs. per linear foot. Does anyone know if this is accurate?
