CPU On the other side of the Motherboard

[Ghost_01]

Hello everyone I am working on a project for school at the moment and I was wondering if there is such thing as Motherboard that has the CPU socket on the back side of it?

If not is there anyway of getting one made or Modifying a current CPU socket on the other side? If anyone has some answers that would be Great!

No, there'd be no way to cool it, you can install the board upside down to have the CPU on the left side of the case, but no way to install a CPU on the back of a board, that's the dumbest idea I've heard for a normal board, what do you need it on the back for?

Yeah, neither do I understand why you would need this in any circumstance.

So the whole idea of the cpu on the other side of the board is to Have the case cool it while having fins on the outer side of the case for better heat reduction.

How would you even put on a heat sink?

That's been done, in a much way, and would be an absolute pain to make, it would need to be an OEM thing and the bill of materials alone would be horrible, R&D would take another healthy swig, and the machining costs would take again another pretty large hunk of money. Obviously there is no way for you to make such a device, and it's a school project, so ignore the fact I just said it won't work, mock something up in solid works, do some bullshit marketing work on it and slap it in to your teacher who probably won't know enough to call out on it.

Motherboard with cpu on the opposite will be in laptops. Then again it will have it on either sides.

Asus ROG Avalon concept has what your asking about. The cpu is still on the top, but rest of the components is moved to the bottom, so that's still like cpu on the underside.

I remember that thing, I thought they stopped working on it other than for OEM machines, try getting companies to agree to that as standard lol. 

[Ghost_01]

The thing is I have machined stuff before and this is a all school year project so I have plenty of time to make it 

[dogetorhue]

I don't think it would possible to make it yourself. Unless you spend years designing your PCB and then manually sourcing components and hand-soldering BGA chips...

I would call that standard ᴉtx

I would call it "HOW MUCH ARE THE CASES?" standard, or HMATC, since making a case for that would be a design "challenge" to put it politely. 

[dogetorhue]

I'm assuming OP isn't using a standard case for this project so why are you worrying so much about that aspect?

IMO manufacturing the case is easy? Much easier than that board and if they have a larger version, the standard for that board will be ∀TX

Do you have any idea how to do PCB work (I make my own PCBs, and I've had some made by companies, there are loads out there) and let me tell you, making a PC motherboard.... Is WELL beyond the scope of any single person, especially for a school project. Now you can get a laptop board and use that, but machining a case... That's expensive, you're gonna need a BIG CNC turret mill, and either aluminium or copper, a large slab of it, since a block of copper that size would be hundreds, go with aluminium.

How low profile does it need to be? https://www.amazon.com/H110T-CSM-LGA1151-Mini-ITX-Motherboard/dp/B01EZGYSGG

For me to be able to slab it on a case and maybe a gpu still on the board

yes, not really wanting to make my own board from scratch but just re design were the CPU is

No it wouldn't, you'd need to design around the envelope of the motherboard, the PCE card being down there and having the motherboard tray above it, it'd be a nightmare to manufacture and assemble, and in such small amounts doing an automated assembly line would be out of the question, you'd be talking CaseLabs case money for a case for that thing, plus it's a dumb layout to start with, why the fuck would anyone want an origami PC like that, that board was basically the engineering team being board since they haven't made an ARES or MARS card recently I think.

That would require making your own board, or turning around an ATX board, but you'd loose all the slots so might as well use a laptop board. That laptop has the GPU and CPU on the other side, like I said, laptop boards are easy to turn around and small enough to make that easy.

True so do think this is the best option? Just for a prototype to see how well it will Work?

When prototyping something, quick, dirty and wet always, you have to prove it works first before you waste money on it. From there you can spend more money or time on it. This is something I do and it usually works out for what I need, but I do not mass produce anything I build, it's usually one off commissions.

Ok so If it dose work out pretty well what kind of labtop motherboard should i get with a decent cpu and gpu
