How a Computer Case Is Built 245

mtxmorph writes "Ever wondered how that pretty case on your desk came to be? Tom's Hardware Guide recently took a trip to China to see the production process for the Chenbro XSpider/Gaming Bomb case. Lots of interesting pictures in this detailed article." I must admit, this is far more intriguing than I'd initially thought, if only for the subtle differences in corporate culture. Chenbro employees have the option of living "on campus" in employee housing.

      Well your plain white box wouldn't be if you bought a "Chenbro XSpider/Gaming Bomb" case. This new case would instead become the ugliest thing in your room.

    The "living on campus" (what is considered by /. readers as a great thing) is not that great. The site is too slow so I can't read the article, though I do know a bit about China factories (living in Hong Kong and having visited a few myself, Hong Kong is part of the Guangdong province, Dongguan is one of the larger cities there). There is an important dark site to this whole China production work.
    The workers often come from far away - all the way from the west is not uncommon. These people come to the east because of the 'good' salaries (typically about 20 RMB per day, or USD2.5, 12 hour days, 7 days a week), to make money and after a year or a few years move back to their village having saved a bit to live from. The working conditions are often harsh, poorly lit rooms, dusty, hot, etc.
    They live on campus, often in single room appartments with shared facilities. Food is provided as well, the fee is normally around USD30 a month. Cheap, for you, but it is half of their salary! And all the rooms have strong iron bars - mainly against theft.
    Margins for these factories are also often really low - cents to the dollar. As a result workers are sometimes treated as slaves, I read regularly stories about this in the Hong Kong newspapers. About workers making just enough to pay for their own stay and the contract cost (often have to pay a commission to a middle man to get the job), and not being allowed to leave the factory. Breach of the one year contract would cost them a fine of about two months salary.
    The products coming from China are wonderful, and wonderfully cheap. Labour cost in China is low - China is now in the middle of the industrial revolution Europe and USA had in the 1800s. With all the poor working conditions and pollution included.
    This is something to realise the next time you buy a case, or another product "made in China"! There is a lot to improve here.

    • Sounds alot like stories of factory visits to Czechoslovakia before communism bit the dust where econo-tourists were presented with gleaming factories for PR purposes when the truth was less than sparkling.

      In all fairness, this facility, the housing and, relatively speaking, the wages do not appear to differ much from manufacturing working conditions in the United States.

    Over and over again, this writeup seemed like it came from a FUD factory. I'm sure that these cases are outstanding -- however, statements like

    unless you buy a quality product you are wasting your money.

    are pure drivel. Buying a $100 case for middle-of-the-road or lower requirements is a waste of money. A machine used to run your OS and assorted apps, with generic HD, motherboard, processor, and drive components does not require a high quality case. Spending $100 on one is simply a waste of dough... and not the converse, as the Tom's journalist -- or Ken -- would have you believe.
    • Nobody would read Tom's. It's geared towards gamers with more money than common sense, who are convinced they need to spend as much as possible, and want to impress all their lamer, I mean gamer, friends, with their big shiny bright green case.

    • Whatever case you get, you want to get something suited to your needs and those of your hardware. If you've got a hot machine, you want to make sure you get a case with plenty of good airflow over the areas that get hot -- and it's no good if it keeps your motherboard cool if it's letting your HD's cook because they're in deadzones without even enough space for convection cooling.

  • Only cases that are hard tooled offer the best levels of quality consistency from case to case. This does not mean that cases produced using soft tooling are inferior, but consistent quality is difficult to control with soft tooling; and the additional time and labor that is required to produce quality soft tooled cases means that manufacturers must charge more for cases made with the soft tooling process to cover their production costs

    So let me get this straight.. hard tooling is better and costs less,
    • No. While they say that hard-tooling is superiour, they do admit that they use soft-tooling as well for lower production amount units.
    • Something I forgot. They also state in the article that the _initial_ costs for hard-tooling equipment are extraordinary high compared to soft-tooling.
    • Hard tooling has a big up-front cost, but a lower per-part cost in production. It's not a small difference, either. Once the dies are made, stamping is an incredibly cheap process. Plasma cutting, laser cutting, water jet cutting, CNC punching, and CNC machining are slow, expensive processes.

      This is a classic manufacturing decision. You face this making quantities of anything from sheet metal or plastic. It's a classic issue in automotive design. It's why low-volume cars often have large fibreglas bo

    • So let me get this straight.. hard tooling is better and costs less, soft tooling is worse and costs more?

      Spend more on hard tooling, and you get a lower cost per part. Very simple.

      Soft tooling is made from less expensive, less durable metals such as soft steel or even aluminum. It can be used to make a few hundred or perhaps a couple thousand parts for prototyping or a small production run. They are cheaper to make not only because the metal is cheaper, but also because the metal is easier to work, so i
      • I take it case-hardening a soft tooling die wouldn't help, due to the high pressures when stamping?
      • Sorry, the words "hard" and "soft" do not describe the metals used in tooling. They describe how two different types of punch press machines perform their function.

        "Hard" tooling of sheet metals means making two large pieces of metal, one with a bunch of holes and the other with a matched set of punches. They operate by stamping a blank sheet of metal in a single stroke and producing an entire pierced and formed part. The press can stamp a high quality part out in seconds. Thus, the savings when makin

          John, while my comments may have been a bit inaccurate with respect to stamping processes, I'm pretty sure that they accurate describe hard vs soft tools for injection molding.
      • That explains one case I had... it had a nice layout, but the metal was thin, and every interior edge was like a razor blade (I actually covered them all with duct tape, to avoid being sliced to ribbons).

    As a software engineer specializing in user-interface design, I don't believe the computer's enclosure is where the user's attention should be focused. "Oooh ... shiny!" So what? A computer user spends most of his time looking at the screen anyway: the case has no purpose other than to support some parts. And the truth is that, whether it be cars, computers, or women, it's what's under the hood that counts.

    It's just ego, really, and the desire to be thought well of by other people. Now, I'm not deriding the ego trip, in and of itself. In the right context, it can be highly motivating. I mean, most of us programmers love to have someone in our own field look at our work and say "Hey ... that's way cool ... how'd you get it to do that?" The desire for more positive feedback of that nature drives us to do even better next time. So if you really want to stand out from the computing crowd, learn coding and do something cool and useful that the rest of us can enjoy, and you'll really impress us. Your shiny new plastic computer case with the electroluminescent panels stuck all over it will not. Put the money into a faster processor or a better video board instead, or better yet some programming classes at your local college.

    To be honest, if some manufacturer were to make a case that blended in with the rest of my office (say, a nice dark woodgrain finish that would match my desk) I'd be first in line to buy it. Some years ago I did something like that. I bought some wood-grain contact paper and covered a mini-tower with it, and spraypainted the front panel a matching color. It looked very nice, fit right in with the rest of the decor. Hm. I may have to try that again, now that you got me thinking about it.
    • Sorry, but likely because you're a software engineer you're not understanding the mindset of many people, for whom the design of an item counts for more than what's under the hood.
      • More the fools they. Billions of dollars are thrown down the toilet every year over such fleeting concepts as style and design. One could argue that this is symptomatic of a systemic failure of American culture.

        The fact that I'm a software engineer has nothing to do with the fact that I can recognize shallow, trite behavior when I see it. And that's irrelevant to my original point which was only meant to apply to computers. All the important action takes place on the screen: all the box does is lie t
  • Its a good article in that is shows that even the simplest parts of our computers have a lot of time invested in their design and manufacturer.

    • I've noticed the same thing -- the early stuff from China was complete crap, very obviously not well made, but over the past 3-4 years has become much better; I no longer cringe at "Made in China", at least for the midrange and better stuff.
