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.
