I'm a bit puzzled.  cpu/mem density is the same as for their older 
dual-node-1U line.  I guess it's handy to have 3 normal disks per node.

hmm, I don't see that stated.  do they have some kind of HS tray?
the boards clearly have ATX-like power connectors, which don't seem HS.

I still don't really understand why blades are considered attractive...

same as a pair of dual-node 1U's though.  there might be some power savings,
as well, though (93% sounds great, but given that each node is probably
>350W, it seems like the 2x1.2KW PSU would be operating at <60% capacity...)

wouldn't the 1.4 KW dissipation be a concern in most any office?
