Preventing Case Corrosion in Salty Environment?

[plzhelp]

Hello everyone,

I've been living in the past year in an apartment right on the ocean in South America, and humidity and corrosion have been a problem. I brought down my computer (simple mid-tower case) and within a year, there was lots of noticeable corrosion. In particular, the corrosion seems to have focused on the side panel and also on the back, where there are air-holes for the side and back fans.

I'm going home for the summer and getting a new rig, but I'm wondering if there is any type of spray, or gel that I might be able to apply in order to protect my case when I take the new one down.

Any ideas?

Wax, you can heat paste wax in the microwave then brush the liquid into the nooks and crannies w/ a paintbrush, afterward remove all the excess with rags and old toothbrushes. I use this method after refurbishing old power tools like my tablesaw that have bare metals which will start to corrode the moment I've finished cleaning.

My dad uses wax oil to seal all the nooks and crannies on cars. He swears by it and it seems to work; it prevents corrosion from road salts, etc.

It stinks for a while after application, but the smell eventually goes away.

Never saw that before daw, I'll have to look for it. dunno if it's on this side of the pond.
I just realized I never specified, I use car wax, no specific brand, just whatever I have handy. If you happen to have a liquid wax so much the better, no need to heat.

Solder a piece of zinc to the bare metal on it. Sacrificial anode.

Buy an all aluminum case? The components inside might still corrode, though.

you could use a chunk of zink like on the bottom of boats, the zinc is more prone to corrosion than the aluminum or steel and is eaten up instead. on boats you need to replace them every few years or so depending on the environment, warm salt waters are much worse than cold fresh waters. just make sure that it is electricly connected to everything that you are trying to protect. you should make sure it is connected to your common ground also, as a very small voltage can be produced ( like a battery)

An aluminum or even an acrylic case might be a good idea.

This is a thread on the [H]ardForum of a user with a very similar problem with corrosion, hopefully some of the replies will be helpful to you.

I liked the charcoal dehumidifier octoberasian posted at the H. I'm sure that could be simplified with fish filters or so. Maybe damp rid
