The biggest technical limitations are motherboard form factors and cases/chassis

Something has went terribly wrong.

Cases are designed for motherboards, motherboard have archaic form factors, and the two are producing most issues with system builds which exist.

PCIe devices are big and heavy, and 2-3 slots wide often. There literally isn’t physical space for then even though the components can easily support it.

Cases have limited design, they force heavy cards to be mounted sideways.

With even a simple moments thought you can see a natural design that falls out, cpu(s) and ddr in the middle, pcie slots either side, 3 spaced, then 2 spaced, then one at the end.

Case horizontal, mount space for radiators above.

Argue about designs gladly.

The point is, the standard motherboard form factors and cases don’t cut it, and haven’t for a very long time.

I have my case horizontaly. liam li evo in 19 inch rack i removed the feet.
Also don’t like hanging those heavy cards on a pci slot.
Always liked the orignal desktop oriantation. kinda went away with atx.

if i look to the design of my motherboard rightnow the graphic card and cpu are smack bang in the midle


i did remove the budha it was stupid

No, I think everything has gone according to plan. It sounds like you are focused on consumer grade desktop cases which is a small industry compared to selling to corporations, and the two have different demands, standards and education.

Corporate computer towers are up right to save space but don’t have big GPUs most places have a dedicated render/high compute server (all servers are horizontal computer case) if not they use workstations built with things like supports and they are not running 4090s (unless for fun). They are running things more like this.

As you can see there is no big logo and rgb everywhere but is at 1/2 the width and 35gb ram compared to a 4090s 12 or so. Why/how less room more performance? Because corporations demands are function, there standards are make it last forever, and they are smart using the right form for the right job. Consumers demand shinny fish tanks with lights everywhere, their standards are low because its about saving $5 then longevity, and some don’t know better.

Both markets are getting what they asked for. The problem is the markets demand, fish bowl rave for lego people or server racks and basic dells.
Then you have home labers between both
Throughing threadripper pro 2tb ram and 7 GPUs in server racks like this.

But shoot, ive seen wall disply cases, I made my own 4 bay raspberry nas a case that is a possible robot. Robots are computer cases, drones and rc cars are computer cases, teslas could be considered giant laptops. Maybe you need to think outside the box because even this can be a motherboard holder.

(No I will not acknowledge crypto bros hot gluing motherboards to plastic cutting boards)

If I could do BGA soldering, and there were nice reference boards designs to copy paste from, I’d be ordering stuff from PCBWay/JLCPCB or whoever, and making some odd shit.
One would be a GPU that uses a standard slot design, but mounts like a giant M.2 drive. And a matching motherboard of course.

IMO this is overstated a bit. ATX works well enough it’s unclear when its limitations will become sufficiently severe to prompt significant conversion to an alternate form factor which resolves them. There’s a some CPU+DDR in the middle workstation and server hardware but the most popular ATX alternative, ITX SFF, goes the opposite direction.

I figure something’ll happen to disrupt ATX eventually but what and when isn’t apparent to me.

Every sizeable-ish corporation I’ve worked for has had a 3-5 year hardware refresh cycle. The large OEMs (Dell, HP, Lenovo) try to generate sales by pushing for three, their buyers usually push back some. But with more then half the places I’ve worked policy’s been any significant hardware failure past the three year OEM warranty’s triggered whole machine replacement.

All the office hardware’s been ATX. Nowhere I’ve worked has deployed workstations, blower GPUs, or dedicated render/high compute servers. In most cases the office spaces and buildings couldn’t support the power density for much of a roll out anyways. Some places have also had rackmount servers, some haven’t, some have run a mix of rack, tower, and other stuff.

Where I work at the moment top of the GPU stack is 7900 XTX and 4080. Can’t do 4090 because there’s a fire safety ban on them and, if that were lifted, most locations would require building upgrades. But 7600 [XT], 4060 [Ti], and 7700 XT are borderline overkill most of the time. Generally we favor cards where it’s a one time RGB disable but there’s a few that need OpenRGB.

Some do, some don’t. Across enthusiast forums like this one I’d say it’s roughly even splits between lit and non-lit builds and between cost conscious and wanting to spend money on higher quality parts. Fishtanks have been trendy for product launches lately but are somewhat uncommon in the parts lists people post. There’s maybe two or three times as many threads for cases with metal on both sides.

Sales volumes would be better data to go by, but those aren’t hardly ever disclosed.

I’m curious who actually buys the Sneaker X, which seems to be selling in higher volume than the Shark X.

Yes just look at how space constrained cases are…

Shit, I could see myself doing this with hardware on par with what I have now, just to do it. And x79 + 980 is not… much. X79 NUC extreme (similar).

exactly all the space is where you dont need it


how you finding the radeon btw? tempted

There are OEM ATX cases from 30 years ago with support slots for these brackets.
DIY market just doesn’t adopt it, because they’re jackasses.

I would disagree with that. If I were to use that case for a server or build a custom loop then that space is exactly where I need it.

For it’s intended purpose it is excellent. As that machine is used for 3D modeling and video rendering, these workloads are perfect. I did do some gaming and cryptographic benchmarking as well which gave me mixed results.

Well I’ve been on this side quest before. One thing with your gpu to m.2 idea, you can get a hat for Raspberry Pis that converts the nvme on the pi to a gpu.

For you wanting to be able to “copy paste” designs and make your own you can! What I do is get just the 3d models of the components and “arrange and path” everything. if you are going this direction you will need to understand pcb architecture but info is out there for that.

What you may want to look into first to understand the architecture and get that “copy paste” is places like this.

The first pcb board that popped up for me is a ddr ram stick. So you have you model you can take it to pcbways or get at least a 500 watt 11,000 rpm small table top cnc machine ($500 or so). but all CAD and CAM software is stupid experience. So don’t use then, use blender for free and a friend of mine made a free plug-in called blendercam that brings all the functionality of CAD and CAM programs to blender and can export G code that your cnc machine can read.

The soldering may not be as bad as you think. I’ll attach two videos one for blendercam and one of a quick overview of the full process of making a board so you have a direction to look at.

This ryzen 9 i have. First procesor i put on eco mode. And i put it on the hardest 65 wat tpd. instead of 170 wat. it cost me about 30% performance. what means this cpu is still fast. Ok if i have some heavy compute. i can put it higher.

And honnestly it feels like the entire system is hapier this way. Les temp. Less power

Get a rackmount case, that will solve some of your problems.
