Balanced Technology eXtended (BTX) Form Factor - The Future of Cases & Motherboards

Graphics in BTX
The vast majority of BTX form factors will see PCI Express based graphics as the choice of video card in these systems. ATI has already announced that they will be releasing a native PCI Express video card once the standard becomes available in platforms. Although you can have multiple widths of PCI Express buses, graphics will use a x16 PCI Express implementation that offers 8GB/s of bandwidth.
This PCI Express x16 slot will soon be home to your graphics card (the little slot is a x1 slot)
A graphics card on a riser in a BTX chassis
As we mentioned before, the graphics card can either be mounted vertically or horizontally via a riser card in a BTX case. If a riser is used, the length of the graphics card will be severely limited - most likely to half-length cards. We'd expect that most enthusiast boards and cases would support vertically mounted graphics cards.
A final point of discussion is cooling; because of the strict cooling definitions within the BTX spec, graphics vendors may be able to rely more and more on passive cooling designs and simply take advantage of the stream of air running over the CPU and chipset. Granted you won't be able to have passive (fanless) designs on the absolute fastest GPUs, but a transition to more passive designs on mainstream solutions would be plausible.

This is a lame arse attempt from Intel in an effort to get everyone to upgrade entire systems.Upgrading means :
(1) profits (PCI-X, new mobos, new CPUs, new bloody everything!)
(2) they can stick in that Secured Computing crap (La Grande) => control what can be played or viewed. Which means RIAA don't have to sue anymore. It also means goodbye P2P, MP3, Region Free DVD, and all the joys of PC. Prepare to be butt-f*ck by MS in all positions.
Remember people this is technology consumers can easily reject.
Simply put, if you don't like it...Don't buy it, don't accept it. There's no one pointing a gun to your head. Intel will see BTX is a failure if no one adopts it.

Well, hopefully AMD will see the light and not jump on the BTX bandwagon. Gone are the days where Intel had no strong competitors. If AMD simply requests their motherboard manufacturers to stick with the ATX format or modified ATX format with several of the changes suggested in this forum, the BTX format will likely die a quick death. I'm not an AMD fanboy (I have 3 Intel computers) but AMD can force such a BTX resistance in the motherboard industry, I'd support them.Anonymous User - Friday, September 19, 2003 - link
My opinions:- Put the CPU in a separate cooling loop. Otherwise your graphics card is going to be suffering trying to cool itself with air at 35°C
- As other people have mentioned: standardise the motherboard plugs for reset/power/speaker.
- Make a standard tiny BTX (femtoBTX?) version, possibly stacked boards with SODIMMs and everything onboard.

What about cards that pop out during shipping. PCI was bad for this, and AGP was worse. I'm scared that PCI-X, especially 1X will be horrible for this. And #53, the ACR was a gateway to the built-in AC'97 codec, especially for modems, if I'm not mistaken.Anonymous User - Friday, September 19, 2003 - link
Everyone here seems to have forgotten about the old "Advanced Communications Riser" or ACR, which was supposed to be a cheap solution for putting on modems, audio cards, etc. I believe this PCI Express x 1 is the revival of this horrible standard.Anonymous User - Friday, September 19, 2003 - link
Hmm, isn't that where the CPU was in the first place (on the old AT boards) before ATX moved it?Anonymous User - Friday, September 19, 2003 - link
What about the new Apple G5 cooling system? Do something like that for PCs with "thermal zones" to dissipate heat and very very quiet:http://www.apple.com/powermac/design.html

Innovation? My Ar$e!This is just a step back to the bad old days of low profile cases & riser cards. Find a pic of an old vtec 486sx and aside form the lack of cooling system *cough* plastic box its the same!
Swicthing everything to the other side of the mobo is a stinky ploy to get us to buy new new cases.
How about dual cpu systems, where will the second cpu go, and will it get its own cooling system (lol), or will we get 2BTX cheep at twice the price.
That and there is no way in hell my 1/2" water cooling setup will fit :|

It all depends on whether a PCIX1 or PCIX16 card will work in a PCIX32 slot. If they do, just MBs with all PCIX32 slots.jema - Friday, September 19, 2003 - link
What I dont like is that they are still going for the 'agp scenario' with one PCI express x16 port one the rest x1. Why not make all the card connectors the same size and speed so you can use what ever card you want in any slot? Not everyone will need the gfx card to have the most bandwith in the machine.
