DEL.
your post is very interesting.
an hp desktop huh ?
if were me and it only had one internal c drive.
i would look at its specs and see if you can add a couple of cheap ssd internal drives. that way you have all sorts of backup flexibility. what model is your HP ?
is cpu i5 8400 or 9400 ?
in RB what does action..audio performance report for no of traks ?

in addition ive been looking at usb audio mixers with lots of inputs funnily enough.
what do you have ?
my top contender so far seems to be the zed series as its 4x4 usb. and people say nice mic pre's.
would appreciate your input.

best
