Hey folks, sorry for the heresy but I'm just looking to connect my old laptop to a thunderbolt 3 docking station (no external gpu needed) to access all the external peripherals through the laptop's expresscard and wanted to see the minimum hardware needed (is this even possible?).  looks like something like an external pcie ( http://www.hwtools.net/Adapter/PE4C%20V3.0.html ) + thunderbolt board ( https://www.amazon.com/GIGABYTE-Alpine-Thunderbolt-Components-GC-Alpine/dp/B0722SV69N ) + some power supply is all i need.  Does this sound correct?  thx

There would be a complex of adapters (Sonnet EC to TB1, TB1 to TB3) & your EC2 port would limit bandwidth to 4Gbps.

Simpler and more cost effective would be a USB 3.0 expresscard + USB 3.0 dock, or upgrade to a Thunderbolt 3 port equipped laptop. The 6th-gen Latitude 5570 is a low cost second-hand ebay purchase. Also, the W520 had a Lenovo dock option to attach peripherals.

hi yeah understood.  we bought the tb3 docking station b/c my wife got a new laptop for school and my w520 is working fine so reluctant to purchase another laptop (it's starting to look like an electronics graveyard here) so if the path was manageable, I'd pursue it.  I really only use it to rdp into work so it doesn't have to be all that fast...

The W520 dock is really cheap on eBay, no Thunderbolt needed. Not sure why simple RDP would need TB at all.
