Let me echo this as someone who once was responsible for HPC computing in a research intensive public university. Most career academics have NO IDEA how much enterprise computing infrastructure costs. If a 1 terabyte USB hard drive is $40 at Costco we (university IT) must be getting a much better deal than that. Take this argument and apply it to any aspect of HPC computing and that's what you're fighting against. The closet with racks of gear and no cooling is another fond memory. Don't forget the AC terminal strips that power the whole thing, sourced from the local dollar store.
