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."
I don't think so. Recycling is the LAST of the three. Reduce, Reuse, Recycle. This will result in MORE resources being spent and LESS reuse of components.
Computer cases are one of the most re-usable elements in a system. My first PC, an 8088 PC, used a Cosmol XT case made of steel, and that case and power supply was the centerpiece of my computer from my XT all the way until my K6-2. Along that time, processor speeds increased by a factor of 100 (4.77MHz to 550MHz), memory size increased by a factor of 50 (256kb to 128MB), storage space increased by a factor of 2000(5MB to 10GB). The important standards for case design didn't change over that period, so there was no good reason to change. Also, the case was totally bad-ass. The computer I built to finally replace the aging beast used a new case, and the standards haven't changed since. I've built Athlon 64s with cases from old Pentium IIs or Athlons.
Making the case of a PC disposable crap is going to result in more waste, not less. Suddenly I won't be able to have the same case for 20 years, I'll have to replace it with every new computer(or more!). Also, it'll lead to less reuse of components. I've built 6 computers this year from parts scavenged from here and there. All of them have found homes. The parts simply wouldn't be able to be scavenged if the machines were made of cardboard. To clean the outsides of the cases, we had to use soap and water that these cases wouldn't stand up to. Some of them were left in the rain and mud for short periods fo time, and wouldn't be functional if not for the fact that they had cases that could withstand the elements.
My current case could last me another 10-20 years easily, depending on what standards do (a PC case you bought in 1999 would have an ATX form factor and could be reused today. I could see power supply standards but not case standards changing again in that time). Under this regimen, I could end up with a new case every 1-2 years or more. As others have pointed out, there will also be greater stress on components from EMI and RFI. Making less durable paper cases may be slightly easier for recycling, but it's stupid from the perspective of reducing waste.
It's been a long time.
