Outdoor Enclosure and Power supply

I been looking for an expensive outdoor enclosure for the last year now. There are a lot available but what I found them to be is extremely expensive, especially when buying from a distributor. I went to my favorite antenna manufacturer in Waterloo Ontario and he sold me the Scepter enclosures. The are fiberglass or plastic type material and are working very well, but the problem is to install the motherboard and power supply I need to put feet on the motherboard and glue it to the back of the enclosure, as shown below.

My new ODU Enclosure are manufactured down the street (I really embarrassed about this because I was searching around the world) and the sales guy came to my house and drop off the units with in 12 hours. What service! But in my defense the name of the company and the listing in the yellow pages did not correspond to these types of boxes. They were billed under switch and fuse assemblers.

These new units are less expensive and have a non metallic backing plate. I will be building two units. Both units will have 200 mW radio cards.

I use regular ATX power supply for two reason.

-They are inexpensive and are able to be obtain quickly.
-They are grounded and the mother board and antenna are grounded.

The Morex power supply is extremely expensive, it is low powered and it is not grounded. It really shouldn't be used for this application. I have a third power supply which is located in my Indoor Units which is a micro power supply that came with slim line case. They are OK as well.
