I'd buy one, but buying these would make my mining rig ROI go through the roof. :/
These trays are targeted for individuals who might not be comfortable with installing their mining rig in a DIY case, or for those who prefer to use a high-quality manufactured (no modifications/additions are required for use), stackable, open-air case that can hold two PSUs and six widely-spaced suspended graphics cards, that could eventually be easily re-sold as a test bench.
