I have been a lurker here for a while but after seeing this, I felt I should take a moment to post.
First off, I have been a MAC user since the late 80's. I work in live entertainment and we use a lot of MAC's in every iteration to perform a lot of functions for live events. We use them to record, we use them to playback audio and video, they present those stellar images you see on giant video walls behind and above stages, we use them to create the stellar graphic images you see on giant video walls behind and above stages, we use them for virtual reality programming not to mention all the laptops and other computers we use for day to day design and operations.
Many of us have been patiently waiting for Apple to produce a new tower that had significantly improved specifications to make it worth the investment in hardware. When the new MAC PROs came out, the very first thing many of us thought was "how in the world are we going to put this in a rack?!" We are not talking about server racks that are placed in some uber air conditioned room on top of a computer floor. Instead we are talking about shock mounted road cases that are packed up every night at midnight, transferred by big burly stage hands, schlepped up with forklifts into the back of semi trailers, slammed in tight along with 70,000 pounds of other gear, trekked across interstates at 70mph whether it is 105 or minus 20 degrees outside, only to be offloaded at 8:00am the following morning by another set of burly stage hands, deployed in position and expected to work with no more than pulling off case lids and plugging the thing in.
In a word; YES we absolutely need something like this.
