eGPU with thunderbolt2 without enclosure

[WillTW]

I want to connect my Dell m3800 to an eGPU but don't want to pay for enclosure. Would it be possible for me to connect this adapter (EXP GDC Laptop External PCI-E Graphics Card https://www.amazon.com/dp/B00Q4VMLF6/ref=cm_sw_r_other_awd_t0CzwbJCHRAHQ) to my laptop with an hdmi to thunderbolt cable? Would I he able to use ANY gpu with this setup and with my laptop? I was looking at this gpu (Sapphire Radeon NITRO R9 380 4GB GDDR5 DL-DVI-I / DL-DVI-D / HDMI / DP Dual-X OC (UEFI) PCI-E Graphics Card 11242-07-20G https://www.amazon.com/dp/B00ZGL8D5M/ref=cm_sw_r_other_awd_15Czwb5V8CZXW) and this psu (EVGA 500 W1 80+, 500W Continuous Power, 3 Year Warranty Power Supply 100-W1-0500-KR https://www.amazon.com/dp/B00H33SFJU/ref=cm_sw_r_other_awd_f7Czwb0KKRQ8Y). I'm trying to do this to avoid spending !) $220 on enclosures like the akitio thunderbolt2. Would my described setup work for me? Also, please offer any suggestions that might improve this setup.

Here is a guy who pulled it off with a Mac, and he has a link at the bottom of the writeup for how to get it working on Windows

I realize you can do this but I was wondering if I can bypass the adapter that u plug the thunderbolt cable into and just use a thunderbolt to hdmi cable

No, an HDMI cable doesn't have the bandwidth to support a GPU. Thunderbolt is much faster, but even so, it barely has enough bandwidth for GPUs. You'll have to use a standard that supports PCI-e speeds. Thunderbolt 3 over USB Type-C will also be an option when it becomes more widely available.
