Well there are some reasons for it.  First, the 220R cost me a whole $1 on 
epay.  Local place too.
So the cost was actually $1.   Had to get power supplies, so that's cost me 
a whole $60
for 3. (2 + spare).  Had memory and processors from an E250 (all Sun 
labeled memory)
which I also got for a song (with a lot of other stuff).  Had drives from 
the E250 (36 GB'ers
so that filled the 220R chassis and the U2 with a nice amount of space)

If it's picky, it really doesn't matter that I buy an empty one and start 
filling it, or start filling this one.
I can put the motherboard in, if I can get the back plate and mounting 
plate and start filling what I have.
The plan to go to 450's anyway....the 400's go to the U2, got a local 
friend who is interested in the 2
300's in the U2. So, it's still an upgrade if I can find the mounting 
cheaply.  It'll end up being much
cheaper than $200 (and a whole lot more fun...8-) )
