CyberPower CRA50001 19" 2U Cantilever Rack Shelf - Heavy Duty Black Server Rack Mount for Network Equipment & Data Center Use

This steel shelf is incredibly sturdy and heavy, rating at up to 175lbs of static load capacity on the specs, but looking at it and seeing how strong it is I believe it could easily hold even more.Putting a desktop on a server rack is a waste of space but I didn't have anywhere else to put it, and it runs on its own like a server anyway so I bought this shelf, mounted it on the rack and placed the desktop on it alongside a small UPS that feeds the desktop in case of power fluctuations. I think both together don't even reach 100lbs but it's nice to know the desktop will not be on the floor.It's a rare thing to need a shelf for a server rack, but I'd highly recommend this one.
