Installation steps

I got the DIY version of this laptop and installed my own RAM, SSD, and WiFi card, all of which I already had lying around. Once Windows was installed, I simply plugged in the eGPU's and after a minute or so, it automagically setup and was working! This laptop has 4x configurable I/O ports which are basically TB4(?) USB-c ports with various options for slide in dongles/adapters (displayport, HDMI, thunderbolt or USB-c, USB-A). If you look underneath, you can see that these dongles/adapters are just plugging into USB-c ports. I plugged 2 of the eGPU's directly into these ports demonstrating that the dongles aren't necessary although they probably provide some protection for the laptop (you can easily replace the dongle if someone trips over the cord) plus it's a little more aesthetically pleasing.  

Benchmarks 

Here's some CUA-z, whatever this tells us. I took these while they were running full blast at cryptomining, FWIW. I'll try to run some benchmarks, but most of the usual benchmarks require some manual adjusting to force them to run on particular GPU's/monitors. 

Comments

I'm currently just using this for cryptocurrency mining, mainly to see if this laptop really can accept 4x eGPU's. After I run some benchmarks, I'm going to compare some deep-learning algorithm training.
