Nick, The Hammond units are good. You may want to get a catalog direct from Hammond - they have a huge range of box types and sizes. One BIG caution: Unless you have a hermetically sealed enclosure - which the Hammonds are not - the enclosure will "breathe" with changes in temperature and the humidity that gets sucked in will condense in cold weather (or whenever the ambient temp falls below the dew point). You can end up with a box full of water since the humidity will "breathe" in easier/faster than the condensed water will leak out. You should put some drain holes in the bottom so that water won't build up in the box. Don't ask how I know this! So, why should you get an expensive "watertight" enclosure if you're just gonna drill holes in it? Good question. You mostly just want to keep liquid water off the electronics. Most any enclosure that keeps water (rain?) off the electronics will work. You may want to conformal coat the boards and mount them vertically so standing water doesn't accumulate on them. My outdoor projects (e.g. gamma match tuning circuit for ham antenna) are made in plain old plastic or aluminum boxes with drain holes in the bottom. Items that can corrode and PCBds are sometimes conformally coated - spray polyurethane from Home Depot works for me for home projects. A good conformal coating tutorial is at: http://www.dowcorning.com/content/etronics/etronicscoat/etronics_cc_tutorial.asp. Humiseal is one of my favorite conformal coating mfrs for commercial applications. They make stuff that's easy to remove/rework but works well as a coating. Their website is: http://www.humiseal.com/protect/guide.htm. Hope this helps.
