Yes, I mean the computer connected to the QB-9 including its power supply,
the connecting USB cable and the software setup.

This is off-topic for the voyage list, so very shortly:
I'm using: http://drc-fir.sourceforge.net/
The idea is to measure the "impulse response" at your listening position
to compute a digital filter that corrects the speakers frequency and
phase response and compensates room reflections. Not too easy to get
started, but this can push systems to another level. Contact me
off-list if you want to know more.

Sure, these disks are pretty silent nowadays, the case might play a bigger
role for the noise than the disk itself.

Another option for you could be to use an Alix board plus a NAS like
IB-NAS4210-B from where you mount via NFS.
