Apple gets FCC approval for Mac Pro tower, and rack-mount version
The Federal Communication Commission has given the all-clear for the Mac Pro, with both the tower and rack-mounted version of the Mac workstation clearing regulatory checks for radio frequency emissions.

A rack-mount Mac Pro undergoing FCC-mandated testing
Initially revealed at WWDC 2019 alongside the new Mac Pro for conventional usage at a desk, little has been heard about the version that is intended to be mounted in a rack and used as a server. However, FCC regulatory filings about the device have surfaced, confirming it is on the way and could arrive soon.
The filing for model number A2304 offer no real major details about the model other than what is already known or expected, such as its appearance. A photograph showing the test setup for the rack-mount Mac Pro shows it to look very close to the version briefly displayed in an image on the WWDC stage, complete with the signature metal lattice and two handles in the front.
Other than the alternate enclosure, it is highly probable the internals will be the same as for the regular Mac Pro, complete with all of the possible upgrade options.
One detail from the filing is that the unit measures 8.58 inches thick. In terms of a typical 19-inch-wide server cabinet, this means the rackable Mac Pro takes up 4.9U of space at 1.75 inches per "U", equating to a 5U enclosure.
Apple is anticipated to start taking orders for the Mac Pro on Tuesday, but it remains to be seen whether the rack-mountable variant will be offered at the same time.

Comments
The top of the enclosure (not the vented side with the handles, but the solid side) supposedly is a door to make servicing easier.
With racks typically down the hall and in a secure room, how would one use one of these?
Incorrect. The Server app was merely for management of built-in services. macOS is true, certified UNIX, which means you can install any number of easily-available services onto it. Everything can be installed via Terminal, you don't need a fancy interface to get things installed and configured.
I run a full web server setup on my MacBook Air for my web development. Nearly identical setup to what I run on my 20+ production servers (all Ubuntu Linux-based). Same software.
I want to see one before ordering, but am ready to get a BTO model.
None ever said (other then this articole) that it was proposed as a server; it is just a new Mac Pro with a rack mountable enclosure. In place where racks are used, it may be convenient to have three or four of them mounted in a rack, may be with video equipement, huge raids, and so on.
I want one because I want a unit that will have a longer shelf life than the sealed up models, can be upgraded/repaired and such. It is one thing to read ad copy, but another to see it in person.
I had a PowerMac G4, G5 and a couple of generations of Intel Mac Pro and all served me well. I expect this one will as well.
