Empty Closet + Computer + 5,000 BTU Air Conditioner?

Heya...

Kind of a weird idea, but, let's see what you guys think.

I was looking into phase and all that.. but I'm worried about condensation and insulation and blah blah blah. Plus the price is kind of high.

Currently my computer is sitting in a tech station, so it's nice and cool on air. Don't want to mess with water really, that's pricey to get into.

So I was wondering... if I emptied out my closet, cut a hole in the door for the AC, and then mounted the AC on the door, put my PC inside the closet, and turned it on full blast... would that keep my PC cool?
Would I really have to worry about condensation at all? (Since the ambient air around the PC would be very low as well)

I could easily get a ~25ft DVI cable for my screen, a few ~25ft male->female 3.5mms for my speakers/headphones/mic, and a ~25ft USB -> USB Mini to a hub for keyboard/mouse/game controller/whatever else, for ~$50 or so. And I already have the rest of the parts.

Any thoughts?

air and water temps are primarily about the ambients, so this would indeed knock quite a bit from your gauges.
lol it would lower your temps yes, but i would consider watercooling first sir. i mean, that's a great idea but what are you going to do about the hole you cut for the a/c when you find out it wasn't all that and a bag of chips? also this sounds like a lot of work for not all that much return.

and do you pay your electric bill? expect it to go up.

Doors are cheap, easily replaceable. It's not a fancy door, just a regular old door. $40-$50 max, if new.

5,000 BTUs are good to significantly cool a regular sized room. Imagine what they'll do for a tiny closet? I think dropping the ambient temperature 20-30 degrees would do wonders for temps.

Yes, but I'm used to high electric bills, you don't know how many computers are running in my house.
Plus ACs in the summer, since the builders did a terrible job with the central air.

I am sure that would work great but then your room would get hot as a furnace. What you would really want to do is put the AC unit outside and pipe the cold air to your computer, and have the extra cool overflow from the closet cool your room as well.

Wow lot of work. As far as condensation goes. Air conditioners are standard dehumidifiers. As such should be able to drop the SH down to around 50gpp. You have to get below 48F to get 100% RH. How cold are you planning on going?

i agree with it making it hot as **** in the room but i think the idea in general is just bad

Not a bad idea - two windows, and one of them isn't far from the closet. Could funnel the air from the AC using a clothes drier pipe and a little duct tape
to the bottom half of the door, then on the top half of the door put another hole and have a personal fan (like a Vornado sized one) blowing out.

As cold as 5,000 BTUs will take me...

Well, the idea of tubing the air to the closet (thanks Fishie) would take care of heat being expelled into the room.

Well then what I am telling you is stay above 48F. Or look into getting some desiccant packs.

Bad idea? How do you think server rooms work? He just wants to make himself a personal server room is all

Hmm, alright.

I could I could go with some kind of case mod for this - I have acrylic laying around. I could build a box that's big enough to fit my tech station (drives/psu would be outside the box) and have two hole on either end, one with the AC air being piped in, the other with a fan pulling the air out.

If I refilled the case with desiccant packs every now and then, would there still be a condensation problem if I went below 48F?

Edit: If I just stuck with the closet - what happens below 48F? I thought condensation what relative, not absolute.

well i know they dont cut holes in the doors and put AC's in them

I don't have a few hundred thousand BTUs to cool a server farm...
Just scale it all down and think that way.

Haha, I think this would be pretty cool, though I have no idea how well it would work. I definitely agree that you need to vent it to outside if you do it, though; I doubt you want to be sitting next to a giant hair dryer!
Just crossed my mind. If using ducting to the closet anyway. Why even use the closet? Why not just duct from AC straight to input fans and exhaust fans?
Alright, so, AC in the window, piped to the closet, then a fan pulling air out of the closet (from higher up, since warmer air rises...) and it'd still be enough to cool the room (hopefully).

Questions:

Would I need to do sections of pipe with fans pulling the cold air along through? Or as long as the pipe is sealed would the air travel through just fine, even if it was a decently long distance? (Window isn't far from the closet, but I'd want to wrap it against the wall so it isn't hanging out in the middle of the room...)

What happens below 48 degrees Fahrenheit?

To hopefully keep my room from getting TOO cold... The 5000 BTU will chill my room if I leave it on full blast and forget to turn it down (while sleeping, even if I wake up and it's 90-100 outside, I'll be almost shivering).

Operating temperature for hard drives??? The sudden cooling of the platters would cause data corruption for sure unless it was maintained at a steady temperature.

Components don't like going from 90 to 50 while they're operating, FYI.
With the ducting you are trying to make a closed system so not sure if I understand your getting cold concerns. But I will also tell you less likely to need to run at full blast as much less volume. Consider.

Well, I'd grab SATA extensions too and house the hard drives/dvd drive outside of the closet.

I thought condensation was relative, and it's a closed system (plus AC = dehumidifier). There's no other issue at below 48F is there?

Also, would these temps affect PSU at all?
