Student Designs Cardboard Computer Case

SpaceGhost writes "The Houston Chronicle has a story on a Grad student at the University of Houston who has designed a cardboard case for a computer. This is not a new concept, but this one is meant to be used in manufacture. The idea is that it will be faster and easier to produce (no fasteners for example) and dramatically easier to recycle."

      Not mine, Enough of mine is made out of plastic for it to be completely worthless. But even if it wasn't, Depending on the frequencies you are trying to shield, your current computer case is a pretty horrible fariday shield as it is. Every hole, slit and opening for ventilation or other purposes allows EM to radiate or re-radiate out of it at a wavelengths of that size.

    As others have pointed out, the case is not difficult to recycle or toxic.

    And who the hell throws away a case? It's the part that goes obsolete slowest, and several computers might occupy a case before it needs to be replaced.

      Yup - almost any OEM case is nearly useless to reuse. Other issues:

      1. Compact designs often only work with specific board layouts (including assumptions of the height of various components on the board and their position.

      2. The case might or might not have a full set of screw-holes for various board formats.

      3. The connectors for USB/power/reset/speaker/etc often use fancy connectors that are non-standard, rather than just individual connectors. There might even be primitive daughterboards involved.

      4. The power supply might or might not be standard ATX. Granted, that isn't case-related per-se, but it is a chunk of gear that has to be tossed. If the power supply does something weird with the power connections/etc then that is a case issue.

      OEMS do all kinds of crazy stuff that makes their hardware almost impossible to recycle...

    They could easily add a thin layer of foil to the cardboard for RF shielding, without it being a metal case (where the metal is also structural and thus much thicker than you need for shielding). However, I imagine this would scupper the ability to recycle the thing

    Anecdotally, I have run many computers without a case (normally when I have been modifying something, or for brief periods when my existing case has insufficient ventilation for new components but I haven't been able to change it. I've not noticed any problems that I did not notice with the case on. Many of the components (the drives for instance) have their own shielding anyway.

    I don't have a quibble with most of your post, but cardboard is a MUCH better dampener of noise and vibrations than metal, especially thin sheet metal. Metal can easily become a sounding board for vibrations. Cardboard, not so much...

    Also, cardboard is pretty structurally strong. Stronger than very thin metal. The only reason cases hold any weight is the internal frame, not the thin sheet metal and plastic most "disposable computer-grade" cases are made out of. That frame could either be retained, or replaced with some triangular corner cardboard reinforcements. It doesn't really get brittle if treated properly (seal it so the humidity remains constant and it can last FAR longer than the 5-year lifespan of the computer inside.

    I see your point on the fireproof thing, though. Once you start effectively fireproofing the cardboard you'll likely undo a lot of the cost savings and environmental benefits.

    I remember playing Tribes 2 on my AMD system many moons ago. It kept locking up about 12 minutes in due to overheating. Finally switched over to an AMD-approved case, and the overheating problems went away. While it would have been nice to keep an old case & keep putting better systems inside, I had no choice on that one.

    I don't miss the old AT cases where to access anything inside meant having to unbolt the side-top-side u-shaped cover. The switch to individual removable sides was a good one.

    And I wonder how much extra ewaste is right now going into dumps because of that crap. Did the environmentalists even bother to see how bad the extra failure rate is for that stuff before forcing it down everyone's throats? Because I have seen a good 400-500% increase in dead electronics due to solder failure.

    IMHO they should have demanded recycling plants for the solder we had, not force an inferior solder down everyone's throats. from talking to my engineer buds they are seeing the same thing as I am-lots of stuff that should be working but failed from the new solder giving out. I think 20 years from now we'll look back on the solder switch as another really bad idea pushed through under 'saving the planet". Whether we'll actually get a functional solder is anyone's guess, as all those failing devices means you have to buy NEW devices, which is of course planned obsolescence at its finest. IMHO the problem was NOT the solder, it was sending the stuff for "recycling" to the third world where it became an eco-disaster. It should have been recycled here and the materials then reused. That would have made more sense and helped the environment more than some faulty new solder that still gets dumped in the third world or ends up in a landfill.

    The case is either Al or steel sheet metal, easily recyclable. The toxic sludge and heavy metals in the PCB, capacitors and solder are the problem. Call me when they invent cardboard solder.

    Bingo. And what about the energy and resources involved in producing the internal components? Apparently these are very high (e.g. in terms of water, etc.)

    I don't want to sound too much like I'm attacking an idea which may well have been intended as no more than an interesting concept (albeit one that's been done and reported on Slashdot on at least one previous occasion).

    We don't want the damned things because the bastards are knuckle busters. you ever have to work in one of those damned HP or Emachines "minicases"? By the end of the day your knuckles are gonna look like you have been punching a brick wall. And i hope you don't want to add anything weird like....ohh I don't know...a second HARD DRIVE!

    Being a PC builder with 15 years in the biz i can tell you there are plenty of those little bastard Emachine, HP, and Dell cases that the ONLY way to keep those bastards from overheating with a second drive, due to the microscopic drive cages that are so damned tiny two hard drives have to practically be taped together to fit, is to use what my former boss called 'white trash cooling". That is where you take and leave off the side of the case and park a $10 Walmart box fan right against the sucker to blow air into the little PITA.

    So you want to know why they use them and we don't? It is because the cheap bastards can save a few cents on metal and since they know EXACTLY which parts they are gonna use they design it for that and ONLY that. Even then they use some seriously fucked up designs to squeeze shit into these little suckers, like the Compaq Deskpro SFF I'm typing this on where the PSU is a fricking triangle! yeah, good luck getting a replacement for THAT sucker. At the same time we PC builders actually want to use standards and have choices in our components. It may not allow us to make little cute "baby" towers, but we can actually use whatever parts we desire without having to buy our cooling for the household aisle at Wally World.

    If you could release a technology which would receive wide support for being "green" but degraded faster than the traditional parts, would you do it? Sure you would - because you could just blame the increased failure rate on the wackos. "Green" and "ecologically responsible" stuff is popular. Just like the current "green" fuels for vehicles (E85, here's looking at you), they don't work out in fact or practice, but they do result in good advertising.

    You and I are not the average PC purchaser - who never opens the machine for three to six years, and then replaces it. For them, the PC *is* just a toaster with more buttons. So long as it works until they feel a need to replace it.

    There were a number of manufacturers experimenting with injection-moulded ABS cases quite a few years ago - they typically needed no tools (or at most a screwdriver for a single screw) to open and service, and could easily be broken down for recycling into a pile of electronics, a stack of plastic and a small amount of sheetmetal. It's quite possible that heavy-duty corrugated cardboard covered with a thin polycarbonate shell and lined with a foil or thin sheetmetal shield woud be able to do just as well for three-year-throw-away consumer-grade computers like most people are using.

    It's also quite hard to see that kind of case taking off for that kind of use, as in five years I expect a three-year-throw-away computer to be about the same size as a hardcover book and easily attach to modular external storage - like what the Mac Mini tries to be.
