No one else has mentioned something that came to mind: if you are a
software company, and would like to try porting your apllication(s) to
the 3K, the lower the price, the easier the entry, and the less you
stand to lose if you discover that it just doesn't quite work or that no
one wants to buy it.

And in keeping with the season, I have a (non-HP) power supply horror
story to share, from a friend who works as a support engineer for the
equivalent of HPRC for a certain large server vendor, not HP, not IBM,
but someone with an industry presence. This is from memory, so I forgive
me if some of the details are inaccurate. They got an order for same-day
delivery of 65 power supplies. They decided to call the customer to
confirm that it wasn't a slip of the fingers on an order of 5 or 6. It
wasn't. Their master electrician had scheduled time for some work, and
all the equipment on that line had been properly powered down. After he
was done, he has bolting the cover back on, and dropped the wrench. On
its way down, it brushed the main breaker, just hard enough to break
contact, sending a spike thru the line. The power supplies of 65 devices
did their jobs and 'took the bullet', leaving them with only the
equipment that had been powered down. So they did need all 65, and they
wanted them that day. I must wonder if they had that same electrician
install any of them...
