Hardware pictures (note: require 5+ posts for “attach files” button to appear. Or can link from say  http://imgur.com  )

TODO.

Installation steps (what did you do to get it all going?)

1) Followed guide on https://egpu.io/forums/deals/worldwide-aliexpress-us70-razer-core-x-chroma-mainboard-add-atx-psu-tb3-cable-for-lowest-cost-100w-pd-tb3-egpu/ to use a Razer Core v2 board from AliExpress with an old PSU and GPU.

Benchmarks (Include a CUDA-Z or AIDA64 bandwidth pic. Optional: Valley3dmark, noting if it’s on internal/external LCD )

TODO.

Comments (eg: how has the eGPU improved your workflow or gaming)

Still seems a bit flaky at the moment. The kernel occasionally has issues adding the PCIe device on attach (dmesg --follow is very helpful), and hot unplugging has crashed the kernel at least once, meaning I tend to plug the board in before booting. Will update as I do more testing.
