@jake4480 Man... that's an interesting "rack" they are using. It seems odd as to what the tech was that they'd manage it this way. Will go look at the link...

@JigmeDatse @jake4480

I'd guess that those are are particleboard do-it-yourself shelves from a department store. With holes cut in the back panel for cables and ventilation. Or the back panels could be left off entirely, though then you'd have trouble keeping them from going all slanty.

@cptbutton @JigmeDatse @jake4480 A diagonal board or two across the back could stabilize the shelves for the most part and still leave lots of air flow and cable space
