Each one of the pull out trays in the picture is ridiculously high powered computer.
They are all ganged together to carry out the required task.
If one of them crashes , only the server room Gnome knows about it. The end user is none the wiser.

They do emit a nice warm draft from the fan trays on the front.
Ah. Thanks, Moosie! That helps. I’ve seen those before, with more or less trays, but was unsure of their function, so I appreciate you telling me.
And now, I’m going to check FB one last time and then head for bed. The barometer is dropping and the crystals in the storm glass are getting denser, so something wicked this way comes.
I would like to be transported to the Sahara for 24 hours, just to warm up enough to make it through the next four months. ;o]
