  • Plexiglas Static

    I'm thinking about making a computer case out of Plexiglas but am wondering if the static that Plexiglas produces will cause problems for the computer. I've seen other Plexiglas computers on the site, do you guys do anything special?

    You can run a ground strap to it to bleed of excess electrons
    Same as you would a metal case...

      I've never actually seen a metal case with a ground strap in it though. Are they really effective on Plexiglas since it's not conductive?

      Will the amount of static in Plexiglas actually cause problems or are you just trying to tell me what to do if I'm paranoid?

      Thanks for the quick response,
      Paul

        A metal case, usually will be in contact with something grounded...
        Can't hurt to strap-down the plexi!

          I don't think the Plexiglas will generate enough static to be of concern.

            It's usually a buildup on the surface, that doesn't seem to 'discharge' like a static shock the way metal does...
            It just kinda makes the arm hair stand on-end

              hmn...
              I'm thinking maybe I'll just mount a thin sheet of metal on one side of the case, and screw the motherboard's screws into the metal and connect the metal to ground.

              That should pretty much take care of any static, right?

                In a normal PC case you the power supply is connected direct to is metal casing via a loop crimped onto the cable. That case is then secured to the pc case and every component from there is secure to the case. Hence they are all grounded to each other.

                In the case of plexiglas to be safe, You would simple redo this with a cable instead of the casing. So on the mainboard using the standoffs and on the harddrives the mounting screws and so forth.

                Plexiglas tho will lead to yes the static issue but also the EM Radiation issue.
                Basicly the metal cage effect protects you and other people from the radiation emitted from the case. With the newer computers this is no so much an issue, But for anyone running an old comptuer with ISA in it then i would consider steering the other direction... But i hope no one builds a carputer with an old system like that.

                  That sounds about right. I took my pc out of it's case and stashed it under my seat, it made my display purple! I put it back in, and no more purple display. However, it worked fine in the house without a case. So from my experience, you have to worry a little more about static in the car.

                    That might have been static, it also could be a crimped / (misaligned) video cable or connector.

                    I have seen the display change colors when the cable is moved on some PCs in and out of the car.

                      I'm positive it was not a cable. I don't know much about static in the car, but I can guarantee the display was purple because of not having a case.

                        No worries, just an alternate potential reason. Glad you have an answer.

                          I don't use a metal case, and my display isn't purple...

                            is your case made out of plywood or MDF?

                              Heh, didn't say that's always the case (no pun intended).
                              As Truckin said, there are many potential reasons. There may be many other factors involved. Maybe if I grounded the motherboard it would fix the problem.
                              The case is not the direct problem, I'm just saying in my car, no case = purple screen.
                              But when I bring it inside, the display is fine.
                              Therefore, there must be some kind of static/intereference in a car that is not present inside. Mind you my computer is from 1999, maybe they make them more resistant now a days :P lol
