I want to put a desktop computer in my outdoor greenhouse. I'm concerned with humidity.?

Question

I don't want to do laptop. What type of considerings, equipment do I need.

Answer 1

Concerned you should be, even if vented to the outside the humidity will build up on the inside of the machine, over time this will cause some amount of condensation. Condensation will eventually cause corrosion etc etc. Computers were not meant for environments such as greenhouses.

Now that all that has been said, with the low cost of hardware, maybe it wont bother you to need to replace the machine or have it serviced regularly.

There are specialized machines built for that type environment they are not inexpensive. Just search for environmentally hardened computers.

Answer 2

They make special cabinets for environments that are not computer friendly (factories, shops etc..). These cabinets filter the air coming into the cabinet and prevent dirt from penetrating into the pc. You could use one of these cabinets and use a vent hose and run it from outside to the cabinet to prevent the high humidity. I hope this helps.
