That's a lot of words for "We put some industrial shelving in a closet with a keyboard and computer monitors, and we made it all beige."
and sadly not too many words on how they made sure those shelves don't vibrate and squeak horribly - which they will if no placed on perfectly smooth surfaces... I somehow could picture something like this to work out nice using metal structural framing - but the pricepoint then probably comes close to quite nice carpentry if you add some bells and whistles.
