Has anyone built a rack for rack mount computers and equipment? I'd be
interested in seeing any pictures or plans you have.

This is OT to the OT:
Back in the days when 386s were the hot thing, and pocket money was
short, I converted an old 4 drawer file cabinet into an elCheapo rack
for four PCs. It was very ugly and the vibration from the muffin fans
nearly drove us to distraction.
What I did was buy the rails from a local supply house and build a
frame around it. Sorry I dont have photos or plans. I did this for a
client that wanted to show off the new server rack in an area that was
glassed in. I made three racks out of Red Oak and used a metal rack
enclosure for a template. Don't forget to add cooling fans, the wood
makes a good insulater for heat.
Happy shooting by the way.

If you mean the kind of rack that used to be called a 19" relay rack, then I
suggest a different approach. The equipment can be quite heavy and the mount
points are fairly critical. Instead of building a wooden rack, how about
getting enclosing a standard metal rack in a wooden case? Years ago, in the
days of CP/M and 8" floppy disks, I build my own S-100 bus computer that
consisted of the man computer case plus a dual disk drive. I used rack mount
cabinets for both of them. I rescued an old 19" full height rack from the
trash at the university, cut it down so that the top would be desktop
height, put large casters on the bottom and enclosed the whole thing with a
desk top surface and raised panel sides. I then made custom fronts for the
components and a pull-out keyboard table.
I don't have it any longer so I cannot send pictures, but you should be able
to get the idea.
Rack mount computer cases would be 19" - same form factor as a relay rack.
Are we talking about full height racks -- 84 or 96", or are we talking about
something smaller, like a portable rack? In either case, I would go the
route Bob suggested -- there are loads of 19" rack configurations on the
market, and they can be purchased as a frame-only to which you could
fabricate a wooden carcass.
the idea of building a wood box for the metal case has other merits...The
metal case acts as grounding for some components and a shield for rf
interference both in and out of the machine. The one picture I saw on this
thread kinda scared me a bit for that reason. most cases if you look close
enough have a removeable front face this can then be replace with whatever
wood you would like and then the rest of the box should be fairly easy to
make just put holes where there are holes for breathing and your there.
Unless you can create the WHOLE universe in 5 days, Then perhaps giving
"advice" to God, isn't such a good idea!
Huh? The system board is the <single> grounding point in a PC. As long as
everything is bonded to the system board you are "grounded".
Well designed system boards don't leak that much RF. I had my PS/2 70 in the
red oak box tested, actually my manager did. It passed FCC "B" level.
Agreed. But most computers are more than a motherboard. As soon as you plug
in daughter boards (I/O, graphics, memory) and run cables to peripherals
like disk drives, there is likely to be considerably more RF.
In any event the OP asked about a rack to hold computer modules. I
understood that to mean that he has fully enclosed cases with rack mount
attachments. The individual cases should provide the RF shielding and the
cases grounds should be connected to a common ground point.
