I recently got a little tablet laptop, and learned that over thunderbolt you could plug in a GPU with a little dock board.

My desktop had a liquid cooled GPU so it became a whole thing to get it out and dockable.

I always wanted to mess with 2020 aluminum extrusion so this was my chance.

Its been a couple weeks work at this point and I'm in the home stretch. I have it running now so its just about tidying up and finding a good way to mount the acrylic panels after doing a final coolant flush

I also wanted to say thank you to all the comments from my last post when i first got my mitre saw for this project. it really made me be cautious when making my cuts, I always took my time clamping my pieces down and then going through the motion of making the cut with the saw powered off before making the cut https://leminal.space/post/24432635

I used an eGPU for a laptop a couple of years ago. When I started to do testing, I found that thunderbolt only had the bandwidth equivalent of less than 8 lanes of PCIe gen 3. This could not be the case anymore if thunderbolt has a new standard.

I think thunderbolt 5 is solid but sadly this tablet is tb4 so it does have a bit of performance loss compared to when it was on my desktop

Well that's extremely neat.

OMG its been a while since I've seen PC modding in the wild, thank you. Cool build!

If you click on the original post it has more photos of the process and it running

This looks really cool..what were the electronic components you needed to build the enclosure? And what was the cost for materials?

I'm using a SFX power supply for powering the GPU and then i got this board that came with the cable https://a.co/d/57Nwws4

Based off of some reviews on https://egpu.io/

Oh man 80/20? That's gotta be an expensive case. How are you fastening the sections? I don't see any corner connectors or anything?

If you click through to the original post I have more pictures there.

I tapped the ends of the cuts and drilled holes on through the other piece and slid screws down the slot and used the drilled hole to get the Allen key through
