Depends how much space you need with the gumstix.

We're using abs boxes from jaycar.com.au

Size depends on the attached hardware.
We have some with sealed lead acid battery and circuit. Others with just 
a powered usb hub.

We fit a small fan to the box and a heat sink to the gumstix to avoid 
overheating.

Ambient air temp in summer here can easily get up to 40 - 45*C.

For outdoor use we mount the abs case inside a metal case or ip65 rated 
case with plenty of ventilation.

For  pc's(not gumstix) have used air-conditioned roadside cases(similar 
to the ones for traffic lights).
On a previous project we measured case air temp in summer hitting 64*C 
mid summer
  (roadside metal case with fan forced ventilation and two industrial 
computers).
Big problem with ventilated cases are ants especially in winter/wet 
weather they love the warm power supplies

fan - 12v fans but run okay from 5V

This is the heatsink we use for the gumstix
