Rated 5 out of 5 by from My Go to Cabinet I am the VP of a small ISV and I have had an opportunity to work with many manufacturers racks. I find the NetShelter SX 42U to be the easiest to work on and has the best suite of options available on the market. I will continue to pick these for deployments and now I understand they are being sold as Dell as their primary rack now that the Dell 4220 has been discontinued.

Rated 5 out of 5 by from The definition of Solid In my role I have had the opportunity to lay hands on data center racks from multiple manufacturers over the years. Without a doubt APC gets my endorsement hands down. They are carefully packaged and shipped so as to avoid any damage in transit. Thanks to the clear instructions, unpacking and installing is easier than an IKEA nightstand, and once in place you can count on years of faithful service. Durability is second to none and the care in design becomes obvious once the cabinet is in play as the features built in place this rack head and shoulders above all comers. No regrets.
