Not x86 is not specific enough. RS6000 series, or
RS6000 model xxxx-xxx would work.
Sun pizza box won't work, but Sparc Station 2, 3, 4, these will; do you see what I
mean?
A good rule of thumb is that if it is IBM and has a square aluminum
tag or rectangle tag with big numbers that take up a lot of the area
of the tag, it is worth putting the side for further questioning. If
it has an oval tag, not so much - but maybe. If it has no tag - just a
label on the back or the letters IBM directly applied to the cabinet -
probably not (yet).
Another good rule of thumb with IBM is if the cabinet is painted any
color other than white, grey, or black, it is worth investigation.
ANYTHING from Control Data, Univac, or Burroughs is worth saving for
questioning. Scrapping such things as these is financially foolish for
the scrapper - real collectors will pay real money.
