I live right next to the sea and have a large window quite close to my computer setup which allows a lot of indirect sunlight to enter.

I'd like to buy or make a cover for my computer system. From visiting my usual mom & pop computer shop yesterday I got the impression these might not really exist any more.

If I make my own I need a material with these qualities;

  • Block or reduce ultraviolet light which can de-polymerize plastics (the sun here in Australia is much stronger than in the northern hemisphere).
  • Block salt-laden sea air which can oxidize USB and other connectors.
  • Not cause static electricity when covering or uncovering.
  • Keep dust off of course

My setup is a laptop plugged into a wide-screen LCD with a few external drives. So I think I'd want a largish sheet to flop over the whole desk.

Are such covers commonly sold these days? What material(s) should I look for which provides the listed attributes?

Glass shields against UV. That is one thing you do not have to worry about unless you open the window. –  Hennes Dec 6 '12 at 22:59
Actually it's a very small room so I leave the window open with just a fly screen most of the time for fresh air unless it's raining or cold. –  hippietrail Dec 6 '12 at 23:02
Not clear -- is this for the system while it's operating, or when it's powered off? If the latter I'd just make (or have my wife make) a "slip cover" for the system, using "outerwear" fabric of some sort. –  Daniel R Hicks Dec 6 '12 at 23:20
Has this actually been a problem? I've never really had an issue with tropical weather and living next to the sea –  Journeyman Geek Dec 6 '12 at 23:31
All the USB ports and one USB stick got oxidised on my previous laptop enough that connections became unreliable when I lived on a Mexican beach for half a year. Oxidization is now just visible on a couple of my current USB devices after spending two summers in a tent on a beach. I'll try to include a photo... Now I'm back in Australia I've got a room over the sea again. In Mexico all of my friends computers had died from the salt in the air and here iron and steel fittings on buildings don't last long. An Amiga 4000 I once owned suffered from too much sun in a less sunny room than this one. –  hippietrail Dec 7 '12 at 3:24
