I was wondering if anyone ever tried making a desk out of two small racks? Both SuperMicro and HP offer 14U racks which seem to be about as tall as the two filing cabinets which currently support my desktop. I contacted SuperMicro about this and they thought it was a bad idea. I would think if anything a couple of small racks would be sturdier than filing cabinets. Has anyone ever done such a thing, and if so how did it turn out?
