For desktop computers, there are also PCIx adapters for Expresscard
which by default only provide the PCIx lane (they have an internal USB
plug on board where you can connect a spare USB line from your mainboard
to make the Expresscard slot work for USB-based Expresscards as well).
They are comparatively cheap as they don't contain significant active
components (or they'd at least bother with a USB connection) and since
they are pass-through, they don't do hotplugging (on the PCIx lane).
The advantage, of course, being that if you have an Expresscard that you
trust with regard to its driver situation and so on, it will work in
your desktop computer as before.
If you are not particularly hot for an Expresscard solution, cheap
Firewire adapters for desktop PCIx are probably worth a try (I think
they were around $10 or less last time I looked).
