Rob is right on it here. I have seen some racks with no space in the back,
and the cables get all twisted together. Then when someone tries to slide
out a draw, something gets disconnected. What is the cost of that downtime?
Everyone has their favorite vendor, but sometimes you have to look beyond
the costs. The lowest cost rack isn't always the cheapest decision in the
long run. The best rack is the one which fits your needs.

We have multiple racks. One thing to consider is the space available
between the doors and the equipment. Some are so close that the doors are
just removed because you'll never get them closed without smashing cables.
Some aren't so bad. Some have enough space to accommodate either duct
work on the front and back, or, a rack mounted cooling unit. Without
direct cooling you may have to cool your room down to beer cold just to
get that thermometer hung on the inside of the rack down to a safe level.
It's an efficiency thing. Not that we used that knowledge when we just
put in new air handling equipment in our new computer room. (And that
special rack is still sitting empty in our lobby where it's been for the
last several years.)
