      So, I suppose that a motherboard with a fan on the north bridge is just as quiet as one without a fan, right?

    A new technology available from Intel in mid-2004, will help to simplify home networking by including a wireless access point and router functionality as an embedded feature of the PC to help minimize the need for external equipment or cables to build a small home network.

              Comparing a 2(?)-year-old OS to a 7+-year-old OS isn't fair. Suspend and hibernate both work fairly well on Win2K and WinXP. (I normally use hibernation...it allows the machine to power off completely, but stores the current state to the HD. It takes a bit longer than suspend as a result, but a power outage won't faze it.)

      As far as I know, upon bootup, the contents of the BIOS are decompressed to RAM to begin operation of the components. Naturally, upon power off, the contents of the RAM are cleared. If MRAM were implemented, even if only for BIOS functions, the entire decompression/hardware detection (IDE devices, kb/mouse, etc) would become null, considering how many hardware changes occur in the average computer between power cycles.
      • Many motherboards now have a case detection switch option. If you implemented this then you could determine if any internal hardware had changed. If you got really froggy you could use sonar to determine the distance to the case lid, that would be fun :) And of course, run hardware autodetection any time the power has been cycled.

      In answer to your question about avoiding rebooting even when the power is down, most likely to be "suspend to disk". Memory contents are copied to a part of the hard disk when you turn "off" and restored if the machine loses power.

      The problem with suspend to disk is that you have to store the "state" of any adapters so that they can be restored too when power is restored. Your add-on adapters need to support this feature otherwise it just wont work, the spec has been out for a while but I'm not sure how well it has been implemented up to now.

    Could read the article because it is slashdotted, but a replacement for atx is really needed.

    At the time of introduction, atx was designed for CPUs with a power dissipation of 10-20W. The cpu socket was placed right under the power suply to cool the heatsink with the airflow of the PS fan.

    Nowaday, 80W CPUs dont benefit from this closeness to another heatsource in the PC. ATX doesnt include anything that allows thermal coupling between board and case (think of audio amp heathsink) or air-tunnels to cool the cpu with air from outside the case.

    Also, eATX boards are quite huge, to big for anything but server cases, but normal atx isnt quite big enough for dual cpu boards with dual channel RAM (or opteron with 4 channel ram).

Of course, the main thing that happens when a new form factor comes out is that everybody who wants to upgrade their motherboard needs to upgrade their case as well which means a nice fat pay-cheque for the the beige box builders... That, more than any technical reason, will probably drive the uptake of BTX.

      Glad you RTFA.

      The PS is identical - same connectors (as long as you have the newer PS w/ the 4-pin 12V connector), same lines, etc.

      Doesn't look like the case needs to change either, although I haven't looked into the nitty gritty details of the mounting holes (appear to be the same at first glance) or volumetric zones (which look interesting; my first glance doesn't show any problems with cases that follow the true ATX spec and don't try to provide side vent holes for the CPU).

      At least BabyAT to ATX made some sense, in that it generally relocated the hotter CPUs next to PSU fans, etc...

      The ATX form factor made no sense at all when it was first released. Which is why it was revised quickly to make up for the utterly braindead ideas in it. The original spec called for the power supply to pull air inward and vent onto the CPU. So you had a huge heat source (the PS) sucking in cool air and then blowing the now warmed air onto an even warmer part of the case that desperately needs cooling (the CPU). The ATX 1.03 spec quickly remedied that and reversed the airflow of the PS back outwards.

      Now you "merely" have one huge heat source (the CPU) located right between two other huge heat sources (PS and video). Yeah, that makes "sense".

      Not to mention issues with putting this into a small form factor case where there is inadequate specs on maximum heights for components.

      I won't even touch the laptop suggestion... other posters have done it justice already.

    PC's should get bigger, not smaller. We have plenty of space on our desktops, so I don't see why I should have to sacrifice speed for space.

    What Intel should do is crank up CPU speeds to unreal heights - like 10 Ghz and put a monster cooling system on it. I don't mind if I have to plug the heat sink system into a separate outlet.

    What Seagate should do is increase HD size to 100 terabytes and put a huge heat sink on that too. If I have to plug the hard drive and heat sink into separate outlets, that should be fine. I have plenty of free outlets on my power strip.

    What NVidia should do is make a triple-slot GeForce FX2. Make it 10 times faster, with a huge huge heat sink fan that I can plug into another outlet.

    With all this, I think the new PC form factor should be a cube, about 3 feet on all sides.

    curious. after looking at the pdf from one of the mirrors, i wondered why the oddball metric measurements- and the answer is they're conversions from english. it's an even 10.5" deep, +/- .01".
    all the other dimensions are based around english measurements, too, and have variances of 1/100 of an inch or .25 millimeter.

    i presume this is for case compatibility, and existing case have slots that work out that way, too, so to avoid having to make a new case that replaces ATX, this is the compromise.

    i wonder though- does this hurt manufacturing in the long run? is it harder for foreign factories to make something that fits *precisely* because of this? having spent much time over the years fighting to make things fit, especially cards, is it time to go to a more exact metric squaring?

    or when manufacturing, does it really matter? is 266.7 mm just as easy to attain as 270?

    some of you mechanical engineers, feel free to add.

    Man they must be joking the standard tower form, has space for 2 Optical Drives (I assume they mean 5 1/4), one Floppy and one hard disk! There isn't even a required gap, in front of the hard disk for a fan!
    It may be great for the processor but it justs sucks for all the other hardware.
