G5 in an iMac

babbage writes "I recently bought a Power Mac G5, and when I registered it with Apple, I was offered a free subscription to MacWorld. When signing up for the subscription, one of the questions you're asked is which Apple product you purchased most recently, and one of the items on the list was 'iMac G5.' Does the MacWorld marketing department know something that the rest of us don't?" Maybe they had seen the page that incognito writes about: "Over at AppleFritter, there's an awesome mod that changes an ordinary iMac into a mini version of the aluminum G5 tower. There were lots of details in the creator's work that leads to a very polished final product."

    Or maybe it was a typo. Someone so used to typing iMac, that when it came time to type just "Mac" in this document, they put an "i" there by mistake.

    This being said, are there any technical reasons a G5 could not be stuffed into an iMac console?

      "Current G5s run pretty hot"

      So, what you are saying is that you can cram G5 hardware into an iMac case. However, you should put metal trays below it to catch the rivulets of melting plastic so they don't damage the finish on your desk.

      Current G5s run pretty hot.

      While they do run warm (and certainly warmer than the G4s used in iMacs, eMacs and PowerBooks), they are still run cooler than most x86 chips, such as the Athlon XP and Pentium 4. The large heatsinks and elaborate cooling system in the PowerMac G5 are more to do with keeping the system cool quietly rather than trying to deal with some non-existent nuclear furnace CPU trapped inside the aluminium case. Remember, any kid with a screwdriver and $30 can keep a raging 3.6GHz Pentium 4 throwing out 100W of heat cool enough to run stably. However, it sounds like a cyclone.


      The challenge with the G5 was not keeping it cool...that's easy. It was keeping it cool and quiet. That is the origin of the G5's elaborate cooling system. Don't misattribute it.

      I'm sure an XServe has less concern about fan noise. The Cobalt RAQ I once used has a 1RU form factor, and no fan on the (900MHz) CPU. It made up for that by having a bank of small fans that ran very fast and very loud. You can do that in rack equipment, but you can't generally do the eqivalent thing in a desktop.

      You're kidding, right? Every G5 I've used was incredibly quiet, much more so than my G4 tower. Unless the side of the case is off and the fans turn to full, my impression of these computers has always been that they are very quiet.

    WWDC should be interesting, since the G5 boxes are overdue for a speedbump, and the iLamp, er, iMac LCD, is also overdue for a refresh. However, since the current iMac's motherboard is based on the powerbook's, I'm not 100% positive that there will be a G5 iMac announced in San Francisco.

      The iMac's motherboard is based on the PowerBook the same way that a Dodge Neon is based on an '81 K-Car. Sure, if you look back far enough, but not so much. The current iLamp iMac is based on the G4 Cube design. The old CRT rev A-D iMacs were based on PowerBook motherboards, and redesigned with the DVs.

    The Cubes failed because they were too expensive-- they weren't a "headless iMac", they were a luxury item that cost more than the stock G4 while delivering fewer features. It wasn't a bare-bones Mac box, it was a costly conversation piece,

    Plus, they had a few well-publicized flaws that made them unappealing... A hair-trigger on/off switch and a lucite case prone to cracks.

    Apple could do well to make a low-end "cube", a cheap and portable desktop without the screen. Include iLife and a Superdrive and it could be sold as a multi-purpose media box, a component of the home entertainment system.

    Well, the monitors have some of the same problems. The touch switches are not incredibly reliable (Apple has gotten much better with them, so they're not as bad as the Cube switches were in the beginning) and that does cause problems.

    The "cracks" were a myth. A few people who bought cubes decided that mold lines (which are present on just about all plastic products) were cracks - and the rumor spread.

    That rumor IS what caused the cube to fail in the market, though. They were selling like crazy at the Apple dealer where I work until that story broke, then sales dropped to almost nothing.

    I also think you're underestimating the market for a cheap headless Mac. If Apple were to ship something in the $500 range (with a useable configuration below $700) I think Apple could take a significant share of the home market. Many people want to pay nearly nothing for a computer, and Apple has no offering in that market segment - even though they've got the best value in the high end of the market.

    I think a $500 box with a G4 (or even a slow G5 - if you underclock them, they're cooler and cheaper than a G4) would sell well - the only problem for Apple would be capacity to build enough of them.

  11. iMac G5 a certainty by DarkVader · · Score: 4, Interesting

    I think we can count on an iMac G5 in the fairly near future. The only reasons not to do it are portable marketing and an abundant supply of the current G4 units. I'm not sure what the supply of G4 iMacs is right now, but I suspect Apple is near a replacement.

    The G5 is a less expensive chip, easy to cool if you underclock it, and should be a good choice for the iMac and eMac very soon.

    (think about it - it's quite possibly costing Apple more money for the iMac processor chips than the G5 tower chips. that alone is a good reason to switch chips.)

    In our area, the cube was useful because of the small footprint and quiet; very much like a G4 iMac would have been.

    The problem was that the combination of a cube and an LCD screen was prohibitively expensive (at least in education); and buying a cube with a CRT monitor defeated the purpose.

    At the end of its lifespan, when the price of cube+LCD became more attractive, we bought (or at least ordered, I don't recall if we ordered them in time) several of them.

    Nowadays, the people who would have purchased a cube purchase an iMac. Not because the iMac is cheaper than the tower, but because it has a small footprint and looks nice on the desktop and isn't overly expensive compared to the tower.

    I'm not sure who in our area would want a headless iMac. The clients who want headless computers also want easy access to RAM, they want PCI cards, they want a tower.
