PCs For A Workshop Environment?

I want to install a cheap, decent PC out there for looking up building plans, shopping for tools while I'm on a job, etc. The shop is going to be in a wooden outbuilding with a shingled roof but the building won't be heated or cooled (although I don't plan on using it much in the summer)."

"I plan on doing things like sawing wood for shelves in here so dust will also be prevalent. Can any of you Slashdotters recommend components for building a machine resilient to cold weather and lots of dust? I was a PC upgrade/repair technician in a former life, so building my own machines is not daunting in the slightest (I've built all my own home machines). The ruggedized machines I've found online are all too pricey, and all seem more designed for avoiding shock damage than environmental dust and cold."

And add a glass-shielded desk (you see those in some retail shops/banks) where your LCD will be lying on its back facing up, covered by a layer of glass. Wireless keyboard and mouse can be regularly cleaned/dusted off or even replaced.

      Actually, the typical computer enclosure is a negative pressure environment with the fans creating a relative vacuum inside the case. Putting nylons (or any other kind of filter) on the fan does nothing except collect whatever dirt and debris made it past the motherboard and other components in the system. Industrial enclosures are usually positive pressure designs, with the fans blowing inward (so that filtering the fan keeps contaminants out) and furthermore because the case is under pressure it keeps dust from coming in any small holes. If you're going to filter a regular computer case, you will need to seal the case completely except for an intake vent, which would have the filter.

    This post is so completely inaccurate, I don't know where to start. I can't believe it was modded "Informative"... oh wait, yes I can. I'll tackle a few points....

    "Building a computer resilient to cold weather should not be a problem in the slightest. In fact, many computers would run effectively much much better in a cold climate. A big factor in the overall heat that the CPU gives off has to do with the ambient temperature"

    The CPU will work fine in the cold, but you're missing the point. The things that will be most affected by the cold are moving parts... fans, and hard drives in particular. When it's really cold, those hard drives might not spin too well. There's also the moisture issue which is going to have bad short term (possible shorts) and long term (corrosion) effects on everything.

    "If you buy slightly new hardware, chances are they are going to give off an immense amount of heat...which is a problem facing microprocessor makers in general, the rising heat problems. Trust me, a Pentium 4 or AMD64 would love a cold climate."

    The AMD64s are renowed for their low heat dissipation. They run at an even lower voltage (and often at a lower clockspeed!) than AMD's previous CPU generation, the AthlonXPs. They also have laptop-like ability to throttle their clockspeed when the CPU is idle, reducing heat output even further.

    "the only thing that the cold will aversely affect is the initial bootup of the machine. Like a car, a computer requires the most energy in the first moments of startup. If you are booting up a computer in a cold environment (a cold cold boot hehe), you may have some problems"

    No, you're totally wrong. A computer does have an initial spike in power draw during bootup (because it's spinning up the drives and fans) but this is less than the power it draws under full load (100% CPU and video usage - ie, gaming).

    And the car battery analogy is totally inappropriate. A car battery can have problems cranking out power in the cold because the chemical reactions in the battery that produce electricity happen more slowly in the cold. That's absolutely not what happens in a computer, where the power supply is simply transforming power from AC to DC. Get it? It's not producing power; it's taking it from the outlet in the wall, transforming it, and sending it to the motherboard and other peripherals. The effect of cold temperatures on the PSU is minimal, if anything.

    There's nothing wrong with not knowing something. The problem is not knowing that you don't know something. I don't know Python or Perl, but that's okay... I don't try and hand out advice on those topics.

    "Although the computer will run fantastic (i wish my room was freezing cold!) in a cold climate"
