Info
I really loved the pocket eGpu and RCC-eGPU2 projects, but never had a system to be able to use it since Deskmini has no Thunderbolt. So almost 2 months ago after learning about Oculink (which uses m.2 and can work on DeskMini, Steam deck, crappy old laptop, etc) I ordered some Riser and cables on Ali express to try to see if it would work. (Since that time, I learned there is an even better successor to the pocket eGpu called OneDock which has TB3 and Oculink, which looks excellent by the way!)
I decided to try to make a dock with internal power and call it OGRE-250 [Oculink GRaphics Expander], a mod to repurpose the HDPlex GAN for use as an Oculink eGpu module. It is .67L with internal power, 62 x 52 x 210mm.
If anyone is interested in making this I will write a more detailed guide, for now I just post the parts and files.
Parts
-HDplex 250w GAN https://hdplex.com/hdplex-fanless-250w-gan-aio-atx-psu.html-ChenYang OCuLink to x16 riser https://www.aliexpress.us/item/3256804863746898.html
-2.54mm two pin Jumper wire
-320 C6 (come with HDPlex)
-CPU 4 pin to SATA (come with HDPlex)
-8pin GPU cable (come with HDPlex)
-3D printed shell
-7x m3 x 5mm screws
-2x m2.5 x 8mm screws (this is for the 320 C6 plug, but instead, I would suggest just hot gluing it)
-1x m3 Threaded insert for the front screw, OD=4.5mm L=5mm
-1x m3 x 8mm to 12mm screw (This is the one in front which will grip the bracket firmly)
For your device to connect:
- Generic OCuLink 4i cable https://www.aliexpress.us/item/2251832871359684.html
- m.2 to OCuLink adapter card https://www.aliexpress.us/item/3256804847640731.html
- Alternate 90 degree m.2 to OCuLink adapter card https://www.aliexpress.us/item/3256804422431762.html
(Cost of all: About $200 USD)

Notes
1) Compatibility is still vague. This worked for me on Deskmini x300 but not on the b660, even though the b660 has no issue driving a GPU over ADT m.2 riser. I'm hoping we can make a compatibility chart with a list of risers and parts that work and which system they worked with.2) Next revision will probably add 40mm cooling fan to keep HDPlex temp stable, it currently can rise above 60C after prolonged period of gaming with 200 watt load. I would only recommend this without a fan if the continuous load is 125 watts or less, then the skin temperature is stable. But if the sustained load is above 125 watts, use with caution.
3) There are some other Oculink hardware combinations which may be better than this one, if someone test a good setup, please suggest it. I am familiar with the OSMeta ones which are good quality but appear to be too large to work in this. There's also all kinds of crazy adapters for Laptops to help expose the Oculink connector like this without having to mod your case. Those can all be found on this TaoBao store: Link
