Is the extender independently powered or is it dependent on power supplied by the PC usb port ? Are the external drives powered by the USB port or do they have external power ? If you plug in the individual drives one at a time to the AIO USB port, do they respond correctly ? a usb port providing power for charging does not require the OS to do anything. It is supposed to only require the PC bios and usb interface controllers to turn on the switch. To access memory on the device for other functions requires higher level control and a device driver to be loaded on the PC. That why you see “ installing your device” and “device ready for use” messages when you plug in a new device on the port.

Looks like there are some intumescent one part PU sprays used for firestop application for walls that might suit.

You just need a bbq !

Just based on molecular weight of the gas molecule.

Make sure the propellant in the foam is non-ignitable as the gas will work its way into the electrical equipment.

A mouse can get through a hole with the area of a US nickel coin

I see two things online for rodents - peppermint oil spray ( maybe not good for cable insulation ?) and medium steel wool with PU or latex expanding foam pushed through it after steel wool pressed into hole. Supposedly mice hate to chew medium steel wool embedded in the foam.

Yeah, lagging only helps if many users are trying to access the server simultaneously. Pretty difficult to saturate a Gbit line. Usually, something else causes the issue - disk access, client device, buffer capacity in the nas, etc. for working on photos, direct attached storage with TB 3/4 or added nvme device internally would be best.

Might look for a rat repellent spray with cat urine . other than a 5,000 v capacitor charge on the the duct……maybe a metalized epoxy or the mineral fiber based sealant used for firebox brickwork ? I have not heard of any PU foam product that is rat resistant.
