homebuilding a case

[Guest]

Archived from groups: alt.comp.hardware.pc-homebuilt (More info?)

My project is to build a wooden case like a big drawer under my desk.
Is there any suggestion? Somebody was talking about metal shielding;
is it so important? In case I would have to line all or part of the
inside with metal.
Wood is a good noise insulator and heat is not going to be an issue
because of good ventilation and airflow.

OK, this means that the shielding IS important. I will make the other
way round then: I will fix metal plates inside my wooden case whose
specific dimensions are very different from the off-the-shelf case. It
is 60x50 the base x40 the third dimension.

You could always scrounge an old atx style case and cut the motherboard part
and I/O bits out and fit those to your wooden case.

Nice idea, it's got me thinking.......now where's my saw....

That metal shielding is very inportant, otherwise all your neighbors are
gonna complain about RF disturbances..

As a matter of fact is exactly what I'm doing. I got free 3 old ATX
cases and removed all the part I need.

I do not have neighbors. Could the RF be a problem for myself?

You could use metal screen on the inside for shielding. Hardware
cloth, or even metal (duct tape) tape will work.

There's an idea! Build the case from wood, then sheath the entire
outer surface with duct tape, the handiman's friend. It will
probably reduce noise, also. Just be careful not to tape over your
multimedia ports.

Outer surface?? Are you joking isn't it? It will be rather ugly. I
would line the inner surfaces.

Well, I was joking. Every now and then I get jocular. No harm
intended. I doubt most forms of duct tape have any metal in them,
anyway -- the duct tape I've bought seems to be plastic with a
metallic color.

But seriously, were I to try to shield a wooden case myself, I
think I'd use the kind of aluminum screen that is used for a
screen door or window. It is a very fine mesh and won't cut the
fingers of the person installing it. It could be glued onto the
inside of the case panels with the contact glue that is used for
gluing down countertops. You apply the glue to both surfaces, let
it dry until it's tacky to the touch, and then press them
together. Very secure bond.

All my appreciation! I keep joking all the time; including when I
receive the tax bill ))

Yes, right; what I'm trying to understand is about the importance of
shielding; I was unaware of this issue.

Not physically, but it will generate a RF disturbance for a few hundred
meters..... TWs, radios etc are affected...

How about one made from cardboard:

Ok, thank you; green light for the shielding

Most of the plastic cases that IBM put out through the years have had a high metallic content paint on the inside of the case
or you could use metalized mylar layered on the inside of the case. The whole idea is to form a closed box with no opening
for the magnetic field to escape.

From what I see on the market none of the cases are 100% closed boxes;
there are several "unshielded" portions.

There shouldn't be.
