This original install used a max3232 level shifter chip cable but all subsequent installs use a USB cell phone data cable from an Audiovox 9100. Now I just just add pin headers to the system board, cut the cable off the cell phone end of the cable and attach a connector to the cable to mate to the pin header on the system board. I snake the USB side of the cable out the space where I'd installed the RJ10 on the original setup.

Out of curiosity, how much power do they use? (I really think power-consumption is more important than performance for a whole host of tasks these days even though it isn't sexy to talk about)

I'm staring at the Plextor power brick and it's power ratings are:
5v 1.5A
12v 1.5A
So that would be worse case.

Datasheet states 15W.
I wish it had 2 NICs, it would make a great PF router for simple home use or, at least, one would hope so.

Depending on your connection speed to the outside world you could consider using a USB 2.0 NIC,
I have several Linksys USB NICs, work fine for my needs.

You should consider using a WRAP device - cheaper alternative to Soekris and works great.

It is good for running spamd.
It makes a good off-site DNS server for lower volume domains
or a master DNS for the internet-connected secondaries.
Add a USB2 802.11g stick and you have a neat little fixed wireless scanner
It could be used as a syslog collector for a site
I think it is ideally suited as a serial-device farm, like my console server or as any sort of network-accessible USB device host.

For simple comparison someone could publish the results of
md5 -t
sha1 -t
easy, in the default install, and gives you a feel of how fast the cpu is.

Just to let you know, their performance is awful if you're thinking in terms of modern desktop/server
grade h/w. However they are pretty damn good at serving up DNS requests, remember we drove the
internet on early Sparc h/w for years.

I spent quite a bit of time looking for an inexpensive mini-USB bulkhead feedthru, but never found
one. There are some available but they are pricey in small quantities, so I just snake the cable out
through the place I mounted the "RJ" connector in the original install.
One thing I forgot to mention, there is an issue with the USB solution. If the USB side is not
connected the USB - RS232 chip is unpowered, and garbage can show up on the input(Rcv) side
of the Plextor, this causes the Plextor to halt at the boot loader. I didn't find this out until the first
USB modified unit was a days flight away. The quick and dirty fix is to plug the USB end back into
the Plextor, just don't try to access the console port from the Plextor. :-) The correct way to fix
this issue is to solder a 10k pullup resistor between Rcv and Vcc on the on the Plextor. However
I'm to lazy to do that.
