If you want to rackmount the switch, choose your switch before you commit to buying a cabinet - patch panels are not very deep, but switches...
I was going to say last night, I really don't agree with the model of high-spec cable, then low-spec switches. Cat5e will cope with gigabit fine, but if you throttle it with a dumb switch, and then compound it by cascading them...
Probably over the top for your needs, but I thought this was good value. 16-port full-managed switch with fibre interface for less than £100?

Or Netgear Prosafe, a cut above the dirt-cheap switches,

These would be more suitable for the compact cabinet you linked to, although they aren't rackmount you can put it in the base of the cab or put a small shelf in.
