Different sup cards.

Main difference is the backplane 32Gbps vs 720.

I believe the 720 is aimed at converged fabric/switch market.

Not sure what budget you are on, but a pair of 3750's as a core with whatever interfaces you require, with 2950s switch's in a stack for desktops work very well and is generally very inexpensive in comparison to chassis gear.

Backup power supply to keep it all up if a ps failure happens (super rare these days)
