I probably do, although I'd have to dig them up; that's one advantage of
PSU modularity.

Trouble is, six of my seven drives (the seventh being an optical drive)
are joined into two RAID arrays: a two-drive RAID-1 array of fast
storage for programs and the OS and so forth, and a four-drive RAID-6
array of slower bulk storage for everything else - and owing to a
misunderstanding when I designed the layout, /var is on the latter, even
though it and its exact contents are apparently necessary for system
operation.

I could at the furthest extreme cut things down to one drive from the
RAID-1 array and two from the RAID-6, but I'd be hesitant to do that,
since I've had data-loss and array-loss scares before; the latter took
3-to-9 months and over $5000 to recover from.


That said, I'd be less concerned about booting to removable media with
*all* of the drives disconnected, and that might achieve the same end.
That goes on my list of things to try next time I do a swap-out for
testing.
