Generally speaking, the thicker the material the more sound absorption

A combination of distance, intervening walls/partitions, and sound
absorbing materials can be balanced to help you reduce the noise
fairly cheaply.

Other things I routinely do for clients, is do put the computer
enclosure in a cabinet, with a sliding shelf/tray, a "flipper door",
and with plenty of ventilation, either at the bakc, or where the vent
will be directed under the desk.

Yes, there is a "nice project" in there somewhere! You have some good
ideas.
Now that I have the noise "at bay", I'll be able to think about what I
want to do.
My new partition was "urgent care"!
