These are my notes on running mac mini mid-2011 with macOS HighSierra 10.13.6 with eGPU.
original:
- mac mini mid-2011, Intel Core i5 2,3 GHz, 16 GB DDR3 RAM, 2 x internal SSD, Intel HD Graphics 3000 512 MB (CPU integrated graphics)
- Eizo EV2313W display (23" 1920 x 1080), connected via HDMI-to-DVI connector
needed:
- eGPU Blackmagic RX 580, sourced locally for 200 EUR
- Thunderbolt 3 -> Thunderbolt 1 adapter (Apple part number MYH93ZM/A), sourced locally for 50 EUR
- Thunderbolt 1 cable (sourced via eBay for 60 EUR)
Total: 310 EUR
The HDMI-to-DVI adapter can be reused to connect the display to the Blackmagic eGPU.

- tech specs for mid-2011/late-2012 mac mini
- most importantly it notes it has single Thunberbolt 1 port
- the difference between these two variants is USB 2 vs. 3: https://everymac.com/systems/apple/mac_mini/mac-mini-aluminum-unibody-faq/differences-between-late-2012-mac-mini-mid-2011-mac-mini-aluminum.html

- this was the macOS update that broke the eGPU compatibility with Thunderbolt 1 & 2 Macs, the PureWrangler fixed the problem

- says this had positive effect on the thermal of the mac mini since the eGPU decodes video, even in the browser (did not say which)
