I want to put together an ultraviolet air cleaner. Commercial ones are
either too expensive, or too small.
I've located all the parts (the lamp and the ballast) except the case. Any
idea where to buy a steel box that's 4 feet long by 1 to 2 foot square? It
should be unpainted. Shinny (polished) interior is even better.
Um, I have it both on paper and Interweb. Sometimes it's quicker to
pickup the ballast and flip through the pages rather than waiting
for the computer to boot up. When I'm not using a computer, I turn
it off. The people who have problems with computers are usually
those who leave them running constantly. I should know, I have to go
fix some today.

That was true of the older computers but not so much with the newer
machines. The biggest problem I find with computers, is dirt, dust
bunnies and dust elephants blocking cooling air to the CPU and power
supply. I like thin clients that have no moving parts for workstations
that are to be left on. The expensive enterprise level parts can be
confined to a server in a controlled environment. Hard drives designed
for servers can take the pounding of 24/7 operation. Most of the boxes
I see in business are using consumer grade hard drives that are not
designed to run 24/7. A little more money to upgrade hardware and the
addition of extra cooling fans and the threat of death if they put the
computer on the damn floor or pile papers and notebooks all around the
poor abused machine, could extend its life and prevent data loss. I
can't seem to convince a lot of owners to have the dirt cleaned out of
their computers two to four times a year, they wait until it quits.
Every year, 13.3 times the tonnage of the Titanic, completely loaded with
coal is put into landfills in the form of old phone books. It was time for
them to move off into history. The yellow pages is in a shambles, rates are
miraculously down, and the only ones that seem to really be making any money
are books for small towns, where they are actually still needed and used.
Go to a local hvac duct fabricator. Just give them your dimensions
and tell them you want a cube, uninsulated. Probably be $60 or so.
Forget about shiney, that would take stainless steel and you don't
want to pay that price. They will provide the openings in the end if
you tell them what sizes you want or you can cut them yourself. If
you are putting this in your hvac return then pickup a couple collars.
