Making a DIY eGPU, question about express card adapters

Hey, I'm planning on making an eGPU enclosure from scratch and I know that getting an actual board that goes from a PCIe slot to thunderbolt isn't available, but I found this Express Card to thunderbolt adapter and I was wondering if having the adapter go with the express card signal lane cord from the EXP GDC board would make it so I can use my graphics card without going into the internals of my laptop. I don't know a whole lot about eGPUs, but I want to know if this is feasible. I'm putting the links below to show the actual product.

Thanks!!

EXP GDC board (have the card in here):

and then I'll have the cord go into this adapter:

and then plug the thunderbolt cable into my laptop

If you have a Thunderbolt port to plug a Thunderbolt cable into, then there are dedicated and significantly faster Thunderbolt enclosures available:

I just don't want to have to spend $400+ buying an enclosure with USB and gigabit Ethernet ports. Cheaper enclosures don't have those kind of ports which sucks.

Thanks though!

From a bandwidth perspective, running a x1 2.0 (4Gbps) expresscard adapter off a 22Gbps TB3 port severly cripples it’s potential bandwidth.

From a cost perspective, when you add the cost of the expresscard eGPU (eg: EXP GDC) + Sonnet TB-to-EC adapter, your in the same cost territory as a basic TB3 eGPU enclosure you can DIY (Highpoint RS6661A, AKiTiO Node LiteAKiTiO Node, Sonnet Breakaway Box).

Good luck with whichever way you go.

There's a couple items mentioned at:
