Putting just the net card on the post probably wouldn't work very well (Yes, that's because of noise on the bus).
However, if the base station computer was inside and had an Ethernet adapter (10base2 would be best, but 10baseT would work too), then a wireless Ethernet bridge could be mounted on the pole with a cable running to the inside.
Finding all weather sealed computer cases are the least of your concerns. They are fairly easy to find, especially if you decide to use a SBC instead of a traditional AT or ATX motherboard. (The slot covers are very difficult to seal on AT/ATX). Do a web search on SBC to find a plethora of single board computer manufacturers. You will probably want to get something in a PC/104+ form factor instead of a backplane based form factor.
Look into the D38999 series of mil-spec connectors for bringing connections out of the box.

Don't forget to chose your components wisely. Get industrial temperature range (-40 to 80C) components where possible, and especially if you intend to use a traditional hard drive. A flash drive is better if you can afford it. Spinning up a mechanical drive when it is too cold can destroy it.
Finally, put some thought into heat dissapation. For outdoor applications it is best to have a sealed box, which means no cooling fans. If you can, choose a low power consumption motherboard. (say a recent 486 class machine.) By all means, get a case that has large cooling fins on it, as that is the ONLY way that you'll ever get heat out of the box.
