Some of the newer workstation/server boards have an internal USB
(female) connector soldered on to the board; specifically meant for
embedded OS.    I have seen it on the Supermicro and Dell systems.

Make sure you do buy industrial quality USB pen drives.  I use Apacer
but there are others in the market.

I prefer to use SATA Disk on Modules (DoM).  For basic server install
a 2GB DoM is plenty.

In either case, do not put swap on the flash drive.
