inexpensive rackmount boxes

What do you guys do for rackmount boxes?  I can’t seem to find any used ones and I’m not sure if putting a metal faceplate on a homemade wooden chassis is a good idea.  In the meantime, I’m considering buying a couple plastic rackmount boxes from Mouser (part numbers 563-PRM-14462 and 563-PRM-14464, page 1183 in catalog 620).  What do you think?

don’t know how many spaces you are looking for, but here are some middle atlantic (really good rack supplies) stuff.. http://www.electroniccity.com/brands/39.asp

i know the small diy electronic shop down the road rom me sells blank  frontpanels from 1sp-8sp and a very limited supply of back casings. the frontpanels usually range from 5-50$ and the back casings are around the same, so going with one of the mid atlantic ones is what i’m going for. hope that helps some.
