I'd be very careful about heat and air circulation if you do this. Obviously you'll want a holes in the back for wires (preferably at the bottom), then another one near the top for warm air to escape. You might even consider putting a tiny electric fan inside that cabinet. Finally I'd install something like SpeedFan to keep an eye on temperatures to make sure they don't get too high and damage circuits.
So recently I've been considering storing my PC tower in a built in cabinet. Myself and my girlfriend each have a cat, so now we have two of these animals running around, plus the rest of the dust in my house. I cleaned out the inside of my desktop today and I was somewhat appalled at the amount of dust that was inside - putting my PC in a cabinet would definitely help this situation, and although the cabinet is fairly large, I'm still not sure it's a good idea and could use some insight.
The inside of the cabinet is about 4 feet wide, 5 feet tall and 16 inches deep.
One of the walls of this built in cabinet is an outside wall. The house is a few hundred years old and the walls have no insulation, so the inside of the cabinet gets pretty chilly during the winter (probably around 50F) when the doors are closed and our heat can't get in.
The front of the cabinet is two glass doors - I can see inside, but there isn't a way for air to easily enter or exit.
I hope my description of the cabinet wasn't too unclear. So my question is this - if I put my desktop PC in this cabinet, is the cabinet large enough to allow sufficient airflow without the PC overheating? Will it be cool enough during the winter to keep the temp down, or is 50F too cold for a PC to run continuously?
Just a note, I keep my PC running all the time.
