A couple of reasons.
A) I did not really want to dismantle the unit to pull the drive out.
B) My desktop is an iMac.

I have plenty of ways of doing it externally, but I really just didn't 
want the hassle of dismantling the cheap plastic enclosure or handling 
the endiannes issues with LUKS (PPC is big-endian).

That looks like it'd do the job nicely excepting the price.

I'd be happy to talk about the encryption system further over a beer 
perhaps but for obvious reasons I don't want to really go into it on the 
net. Unfortunately due to personal circumstance I'm not likely to make a 
PLUG meeting in the next couple of months. In fact I don't think I've 
been to a PLUG function since an installfest somewhere around the year 2000.

I'm only mitigating against inadvertent or deliberate disclosure via 
physical theft of one or more machines. If you got root on any of the 
equipment while it was powered up and connected to my network it 
wouldn't take long to figure out how to get the keys, but that's not 
what I'm protecting against.
