Being a UNIX guy maybe I lack some basic understanding, but where is the deal on the R410?

You could get a much better machine from -say- HP (DL380G6 491332-001) for 3,5k [1], and though IBM doesn´t disclose prices on the x3650M2, I know we pay a lot less than 5k for a pretty decent 3650M2 (but I´m not allowed to tell you how much ;)).

What did I miss?

Paris, because of confusion.

[1]ok, without a drive, but you´ll surely be able to find one for the 1500 USD difference.
