Good Afternoon
    I'm considering buying a small quantity of refurbished computers.  I'd
like to feel comfortable that they are supported properly in RH7.2.  They
likely will be mainstream off-lease machines, so they should be fine, but I
don't want any surprises.  Is there any way I can do that while I'm standing
in the computer store short of doing a either doing full install or trying
to find some sort of compatibility chart and taking it with me?
