Cat45xx-sup7 in a nice little box? Looks like a much improved 4900M in
many ways (1U-ness, SFP+-ness, perf upgrade, airflow path). Moves from 800
to 1100BTU/hr, but can't see that mattering in the applications I'm
thinking of.

Hopefully cheaper than the Nexus5500/2000fex route for us smaller folks.
