    I've seen a lot of "case mods", but this has to be by-far the most practical of them all. It's portable, it has a handle, and the insides are very easily accessible. Find a toolbox that has a bit more protection for ruggedness (rubber corners maybe?) and maybe a little deeper to provide room for cables, mouse, and a small keyboard and you have the perfect LAN party box :)
    • If you wanted to go all out portable machine, you could mount a small (5" or so) lcd in the top (you'd have to move a fan) and have a full computer in a box. Get a foldable pda keyboard and a small mouse. Stuff 'em in the box for travel and plug into the front usb ports - it's the perfect traveling computer repairman box. That gives me an idea...
    • I actually like the "aluminum briefcase" mods that I have seen. Much more stylish than a plastic toolbox. Don't get me wrong, it is still cool, but not the coolest.

    Those toolboxes are rather cheap to buy. Pity they don't offer too much EMI protection as metal cases do. Those computers are rather noisy thingies what comes to radio frequencies..

    Anyway, that case seems rather well built and easy to carry around. Optimum would be that everything including game controllers and flat screen display would fit into box.

    This is much nicer solution than the urethane foam mess which was admired here a little time ago. (Hey, you can cast your computer in concrete and it still might work - it is not too smart though.)
    • Strangely enough, concrete conducts electricity too well, from what I've heard. Not from anyone doing case mods, of course. Just people who have worked with car batteries and electrical equipment.
  • A local computer shop gave me a spare backplane for all the ports when I came in looking for one. Sweet!

    That is the mark of a cool local computer store, just the type I like. :) I don't use CEX or Maplin unless I've got no choice.

    This would make a pretty nice addition to my collection of toolboxen. I have a couple different tool sets configured for working on a different variety of things (boxes I take to my friends' houses when they have this kind of trouble or that...). Sometimes I end up taking along multiple boxes because I just don't feel like switching things around (and it's good to have more tools at your disposal anyway - you never know!) But someone with a computer problem - just throw this baby in the trunk and go!

    Ok, well don't 'throw' it. If (not 'if' but 'when') I build one of these, I'll be sure to add some shock protection to the mobo and CD drive. A keyboard holder inside the unit would be pretty nice too. Carry it all in one go. Fit an inexpensive flatscreen inside the cover case you've no CRT to hook up to and you're good to go.

      I've been wondering if you really need an inverter. From my inspection of power supplies, the typical design seems to rectify the mains voltage, then "chops" it through a small isolation step-down transformer, and rectifies it to about 25 volts. Then I think this DC voltage is used to drive the voltage regulators for your 5, 12, and 3.3 volts, etc. My guess is that maybe you could disconnect the mains circuitry and the isolation transformer, and apply battery power directly to 25 volt supply node.

      All PC power supplies are pretty much the same; I wonder if there is a schematic posted anywhere on the net. There has to be more efficient way of doing this than stepping up a battery voltage through an inverter, and then immeadiatlely stepping it down again. Driving the voltage regulators directly from a DC supply would be much more efficient, and of course much cooler with regard to temperature.

      • Congratulations! You have just built your self a ... (rather crapy) laptop!

        Sorry couldn't resist.

        • Congratulations! You have just built your self a ... (rather crapy) laptop!

          Sorry couldn't resist.

          True. Very true (you made me smile). But the best part about something like this is that I can use PCI/AGP cards! It's portable - and with a little flat screen built into the top lid, keyboard resting inside....

          Well it wouldn't exactly be a laptop - but you sure could put it on a table - and you could get REAL video, real sound, do video capture, throw a DAQ card in there, etc. - WIHTOUT paying the PCIMCIA/CardBus tax.....
      • Wow! You are so correct! One could construct this such that either a normal powersupply (one you connect to the wall) OR a battery based power source (wired into the original supply as you state) could power the thing. You could also quite easily build a regulator circut and employ the use of some switchers and or linear devices (free samples at National Semiconductor [national.com]) to provide all your voltages from 12 or 24V. Not bad.... Just put as many battery packs in there as you can fit/cary and wire them in parallel! Construct a charger circuit that tops off the batteries whenever you're plugged into the wall! ... bingo!

        Yes you are very correct. 12vDC->120vAC then back again, all within the same box - bad. 12vDC -> directly to the board, with some regulators to produce your +-5v, etc. - good.
      • I've been wondering if you really need an inverter. From my inspection of power supplies, the typical design seems to rectify the mains voltage, then "chops" it through a small isolation step-down transformer, and rectifies it to about 25 volts. Then I think this DC voltage is used to drive the voltage regulators for your 5, 12, and 3.3 volts, etc. My guess is that maybe you could disconnect the mains circuitry and the isolation transformer, and apply battery power directly to 25 volt supply node.

        That wouldn't work. A typical switching power supply works by rectifying the AC input directly (hence the large 200-400V capacitors), then using an oscillator to generate a high-frequency (usually square-wave) high-voltage AC. This then goes to a multi-tap transformer that steps the voltage down to a few different levels at different taps.

        The voltage regulation is handled by both the low and high-voltage sides; the switching duty-cycle is modified based on the output voltage. All of this results in much more efficiency than 60 Hz line frequency, which is why a switching supply can be so small compared to a standard transformer-based supply (think laptop power supplies). Working with sine-wave low-frequency AC results in lots of unnecessary heat dissipation etc.

        Some cheaper PC supplies also use a 7905 to regulate the -5V side, and a 7912 for the -12V, as it's cheaper -- but you can only draw about an amp from these regulators, though these two voltages are rarely needed (-12V is needed for standard serial ports I believe).

        So, you couldn't just stick a DC 12V supply somewhere in the mix. You might could get away with building a DC regulator for the 5V and 3.3V supplies, but you wouldn't be able to regulate the 12V side very well (you lose at least 0.7V as a result of regulation).

        Believe it or not, it is many many times more efficient to use a DC-AC inverter (usually also based on a MOSFET switching supply) feeding a PC power supply than it is to try and regulate DC, which involves dissipating excess as heat. While on the surface it sounds wasteful, you'd get much more battery time with the inverter, plus you're assured to have all of the correct voltage taps needed by the system.

        I experimented with this quite a bit personally, and the DC-AC-DC process is much more efficient. Think about how a UPS works...
    • Dual 12V battery pack with inverter could go in there too..

      And there you have a nice, 40 pound laptop. I have a Compaq 'Portable' 286 that met your specs except for the batteries. Be sure that you use lead-acid. You wouldn't want to be too practical ;)
      • Well.... What's your typical toolbox weigh? I've got a few that weigh at least that. I never called the thing a laptop - and this'd be much more powerful than your 286, and this could run on batteries (well - maybe for a few minutes anyway). I had one of those Compaq's too. Had to plug it into the wall - and it was next to useless as a computer (what? - 20Meg HD? - 286 won't run most of the free unix derivatives....) ==Really cool plasma display though, eh?==:)

        So 'practicality' is dependant on this intended use. As something you can throw in your briefcase or backpack - no. As a more-or-less complete machine, that's servicable, low profile, has a built in handle, you can throw real hardware into (debugging the flaky network card that's in your machine in the cage at the colo...), and easily upgradeable - then well... you decide.

        I think it'd make a great field machine. I work in greenhouse reasearch. Sometimes having a real computer as portable as this could be a real benefit. - the ability to throw an A/D card into something like this in the field to log thermocouple measurements, or for example when you need more than 2 serial ports on a single machine. Our lab has handfuls of old serial port cards - no PCMCIA serial cards and dongles laying around though.... I think this is pretty neat - at least for industrial work, computer repair/network diagnosis, hobby computer technician, or even just the handyman that can use computers to solve problems.... Great idea on the part of this ArsMan....Nicely done.

    • Hmmm, interesting....

      Bear in mind, you won't be able to use IDE drives. Maximum useful length for those cables is 2 or 3 feet. SCSI could probably handle it. Go firewire and you could keep it on the other end of town.

      Other than that, I don't see too many problems with it. You'd probably want to power the drives with a local PSU slaved to the one by the mobo. Wireless keyboard and mouse, obviously. I dunno if you'd need any amplification on the monitor signal, though.

Also, would it cause cell phone / portable phone interference, or do those operate at a different enough frequency?

    • One thing to remember at a lan party is everyone's computers are generally shielded, so one unshielded box I don't think would cause a problem...

      My buddy got tired of pulling his case apart and just started running around with the thing open the the world -- including at gaming parties. Never seemed to be a problem with other computers or anything else (he always sits in my computer room with me).

    Thanks all; I'm glad so many of you like the box. And for those who think it's ugly: be glad I didn't use the yellow version of the toolbox. As I said on the page, it's meant for my daughter. If it was meant to be more high-performance I would have chosen a different mobo with more appropriate specs. Even now it would would do great for LAN parties if I dropped in a decent vid card.

    About balance: yes, it is a little heavier on one side than the other, but not overly so. It's easy to carry from either direction, because the PSU is still fairly central.

    About the size of the box: I would have loved to get a toolbox big enough for peripherals, but I just couldn't find one. I looked all over town and this was the best I could do. Virtually every toolbox I found was too narrow to hold a motherboard. There were plenty wider and taller, but most toolboxes were less than 8" deep, front to back.

    As for why the page is hosted on AOL; I've explained it before when I catch flak at Ars about my AOL-ness, but I won't go into it all. Suffice it to say that my main connection is cable. I pay $0 for the AOL, so why not use it?

    Yes, I am a lowly user of Win98. It does what I want it to do. My wife is OK with it, too. Sorry if it bugs you. ;)

    As for the Jergens... take a look at the pic. Wolf mousepad, turtles and wolves on top of the monitor. What does it add up to? I'll tell you: it's my wife's desk in the living room. It was much easier to plug it all in there since her machine was already down with a bad mobo.

    Frankly, anyone who could recognize that bottle as Jergens specifically, must have some of their own...

      The hard drive beneath the PSU should be fine. The front intake fan is blowing in right in that area. Part of that air goes directly into the venting on the front of the PSU, and the PSU fan should then be sucking all of that straight out the back. There is no venting on the underside of the PSU, so there is the bottom of the PSU as well as the top of the drive cage in between the PSU and the hard drive.

      The case temp as read by the motherboard has hovered at 22C ever since I set it up. None of the exhust streams are very warm, and nowhere on the outside is warm to the touch.
