I wish the FCC would go back to doing their job re: radio interference and unintentional emissions. The entire concept of a computer case 'window' is about equally as anti-social and rude as littering in a public park. But it's so pervasive and socially accepted when I bring it up the only responses I receive are all quite hostile. Even worse are the computer builds that don't have any metal case at all. They're broadcasting that <30 MHz interference from the high speed switching electronics around the world, ruining a shared medium for everyone, and they have no idea.
And really, it's not the consumer's place to be aware of these things. It's the regulators'. And they've dropped the ball.
- transpute 1y ago> computer builds that don't have any metal case at all Would be nice to have more metal cases for SBCs, like the one on R4S, https://www.androidpimp.com/embedded/nanopi-r4s-review https://www.androidpimp.com/embedded/nanopi-r4s-review KKSB makes metal cases for some SBCs, https://kksb-cases.com https://kksb-cases.com
- superkuh 1y agoI run a handful of odroid sbcs constantly with 3x rtl-sdr usb radio receivers each. For their cases I used the cardboard box they shipped in covered in overlapping 2" conductive-glue backed copper tape. And lots of type/mix 63 ferrites on the cords.
- oakwhiz 1y agoMetallized windows would be nice at least
- transpute 1y agoOne workaround is conductive mesh (metal/fabric) over the window interior, bridged to bare metal of the case interior.
- dontlaugh 1y agoI also don’t get the point. Why would you want to look inside your PC or even have lots of coloured lights in it to look at?
- sokoloff 1y agoI think the insides of a PC look more interesting than a flat piece of sheet metal. Adding addressable LEDs make that even more true. Visually, I don't care particularly much one way or the other, but on a 6-12 layer PCB, there's plenty of opportunity to closely couple and shield fast-changing signals, so I wouldn't expect surrounding in a Faraday cage would be needed (and certainly I've never noticed an issue from the computers near my RF receivers).
- dontlaugh 1y agoNeither is very visible under your desk, except for possibly the front of the case. I went out of my way to avoid extra lights, which sadly wasn’t possible for the GPU. I had to figure out how to turn those off in software.
- superkuh 1y agoIt is a form of costly signalling.
