Yo Dawg, I heard you like PCs - der8auer converts Intel NUC into a PCIe card with just some tape.

I leave for a couple months and a template gets added to the forums, wonder where they got that from.聽馃憖
Rumors of my death have been greatly exaggerated


Summary:

Despite what Intel may have said, the Intel NUC does not require an extra enclosure but can easily be added to any existing PC with just a few pieces of tape.聽

I have a lot of contact with youtubers and streamers who start their career and most of them at a certain point like to have a second system to capture their signal, processing, streaming or data but the Intel NUC can take over this process completely, without requiring an additional case, additional PSU, you can simply plug it in. When I told Intel about that, that I would use the NUC for that use case, they said "The NUC isn't designed to be plugged into a main board". It's just an adapter with a base plate, plugged into other [Graphics Card], but there should be ways we can fix this. We just tape the ID pins and therefore the slot would have no idea that the PCIe device is plugged. Voltage聽like 3.3V would still be present and there would not be an issue, but that would be the way to fool the motherboard to still get the supply voltage of 3.3V to our NUC and not stealing any PCIe lanes. Taping the most slot from the backside, left 1 empty which is ground next to the slot, then we have 2x 12v and an additional ground. Front side looks similar except we had to tape an additional pin and didn't have to tape 1 on this side because it's not ID, also 12v and ground. We're not stealing any PCIe lanes from the system.

My Thoughts:

While still potentially a bit more expensive than a regular PC, it's neat to see that a NUC can easily be added just like you would add an additional GPU. I might consider this as you don't even need a case that can support two systems, any regular ATX case will do.

TLDR:聽that the PCIE slot on that NUC is "reversed?". The connector is male so without the female-female adapter to connect a GPU and PSU the card wont boot. However if you cover the data pins and connect it to a normal motherboard it will boot in onboard graphics (iGPU) only mode as the motherboard and EPS 12v (CPU PSU plug) on the NUC is all that you need.

Flag penalty! No go. A modern MB isn't a backplane, so you won't be able to make a blade system out of these.聽

In terms of functionality what does this enable?

Apart from doing it for the lols to have a PC inside a PC

Did anybody actually watch the video? The NUC booted fine in the PCIe slot without the tape, the only reason he added the tape was because the slot was detecting an X16 device connected and was reserving 8 PCIe lanes from the GPU in the other slot which were not needed.

The Kapton Tape was not required for the NUC to boot.

Roman suggested being able to game on the main PC while capturing and streaming on the NUC.

I admit, your excellent template was, erm, borrowed in the creation of the official one

If the direct PCIE connection eliminates the need to modulate/demodulate over a conventional 2 PC setup (in same fashion as AMD crossfire over pcie with the graphics card) I could see some efficiency gain with this.

Otherwise there is no difference to have the NUC outside apart from not requiring the additional power brick.

As long as the performance is sufficient, having one case instead of two can be a big difference in terms of looks and space. We will know more after the next vid.

The videos from Roman are always original and super interesting, he is one of my favourite content creators at the moment.


That said I think in the end is actually a pretty聽sketchy solution, if the goal is to have a second system for video capturing and streaming then I think it would be better to get a two-system case.

In this configuration the NUC does not have a PCIe slot for capture cards so you are forced to use either USB or Thunderbolt (unless using an M.2 adapter, not sure if it is possible tho), there are no chances to upgrade or swap parts since the CPU is soldered to the mainboard, and I am also pretty sure that you can build a (way?) better and cheaper ITX based system.

you know the time linus was sponsored a trip to the EPYC server assembly centre, and he showed how two Instinct cards were stacked in a 1U subsection?

kinda want someone to build a system like that. could be even smaller than the skyreach 4 mini
