Desktop metal shielded PC case?
I'm looking for a solid desktop (either pizza-box or mini-tower)
computer case that has an all-metal exterior for shielding RFI. This is for use around radios etc. I realize that SVGA monitors, mice, and keyboard leak too, but right now I'm looking mainly at the PC box. Most of the cheaper cases come pretty close to good shielding, but they have these plastic filler panels in the drive bays that offer no shielding and let a lot of RF leak out. Most of the fancier cases in the computer stores around here have humongous plastic pieces on the side. I'm looking for all-metal. Rack-mount server cases seem to be pretty good in terms of metal shielding all around but I need something for desktop use. Any suggestions? If all else fails I can just put some perforated metal over the holes in a cheap case, but I'd rather just buy a good case to begin with. Tim. |

http://www.directron.com/pc75.html I have even seen an all stainless steel case which is used around food production plants... can't find anything close with google though... Son has an all aluminum case, $175.00 is what he paid for it!--OUCH!!!!

You could always shield the plastic panels with copper or aluminum foil or
screen--etc... (on the inside--out of sight) Warmest regards, John -- If "God"--expecting an angel... if evolution--expecting an alien... just wondering if I will be able to tell the difference!

What about that gaping big square-foot hole in the side? I have even seen an all stainless steel case which is used around food The old "PC Power and Cooling" all-metal-tower used to be good (I think it was available in chrome!), but they don't sell them anymore (probably because they cost several hundred $). I'm not looking for anything particularly stylish. Just a case without big holes covered by plastic. Tim. |
Personally, I'd place a sheet of aluminum window screen between the acrylic
sheet and the case--that way I could still get the effect of looking into the case, and still be shielded... Other than that, I'd pick the one from their catalog which DOESN'T have the "big gaping hole" in the side... grin Warmest regards, John -- If "God"--expecting an angel... if evolution--expecting an alien... just wondering if I will be able to tell the difference!

My 3.3Ghz seems to broadcast on most frequencies--from rfi in the am radio,
fm radio, sw bands, etc... toroid chokes on the phone/modem/net card cables helps a lot...

What band does a PC broadcast on? -- Jeremy Boden It depends on the computer. What he said. Usually on all harmonics of each clock in the box, from ~1.8 MHz on up to near daylight -- or at least well past 70 cm., in the case of the boxes here at home and at work. Add in all their cross-modulation products as well, and it starts to look pretty gross. One of these days I'll borrow a spectrum analyzer and see what's coming from where. I know that the bedroom TV puts out a lot of stuff around 3.5-4.0 MHz. and the cable box is pretty noisy, too. Hard to hear DX over all the in-house QRM. -- Mike Andrews W5EGO 5WPM Extra Tired old sysadmin working on his code speed |
