    There are jumpers on the motherboard, but they are
    hard-wired at the factory.  This is probably a good
    thing, since when we brought up the Raq-4 we found
    all sorts of interesting thermal issues with the
    450 MHz processor.

    Cooling things in a 1U form factor is not trivial.
    Doing things that add heat and draw extra power,
    such as faster CPU's and different disks can have
    strange and odd side effects.
