Phoronix published a review on the StarTech.com 42U Low-Cost Server Rack Cabinet
A quote from the article:
In the process of building our new open-source, Linux benchmarking test farm the server racks I settled for are the StarTech.com 42U rack cabinets. I've bought three of these StarTech.com 42U (4POSTRACK42) racks in the past few weeks and have been happy with their quality for low-price and it includes casters, levelers, and cable management hooks.StarTech.com 42U Low-Cost Server Rack Cabinet @ Phoronix
