this works perfect 10Gb Mellanox ConnectX-3 MCX312A-XCBT and as my pic above, you can just use the low profile pci bracket it comes with, it fits fine, does look a bit strange but does the job and is secure.

There are some experiences earlier in the thread and a photo from @cptcrunch on the first page. It looks like a little surgery might be required to get it to fit physically but the riser should be fine.
So I'm working on my eGPU install now on my P350 Tiny. Can confirm the x8 or x16 risers don't work consistently with the official Lenovo thunderbolt card. Using the Tiny5 x4 riser seems to consistently work for me at least in detecting a TB card.
However I can't for the life of me get the eGPU detected. Has anyone had luck with Ubuntu and this Thunderbolt eGPU situation (headlessly)? lspci doesn't detect any GPU but does detect the TB. Boltctl however shows it as disconnected.
Syslog has the following error

Yeah I thought the same but there are precious few tbolt settings in the p350 bios and basically just enable/disable protection (it's off) and a power management enabler. I'll check i've cycled through all the combinatorics but think I have...
I haven't had the time to do the work to look into it, so for now I'm just providing a link to the post so people can be aware and make their own assessment. My own view is that for the vast majority of requirements these architectural minutiae are probably not of great concern either way, but I can see that for some they are very important so it is worth flagging.
In the meantime if someone wants to delve into it in detail to create some firm guidance, I would be happy to summarise what they find in the first post.
Hi,
Sorry, no thunderbolt experience but I know you had to install a driver for Windows (see this forum thread for more informations). Did you try sudo apt install bolt (saw it in this guide)?
yes it's weirdly erratic. it seems like a Ubuntu kernel config issue but i can't get it consistently to recognize the enclosure. i need to try and find an alternate device to see if I can get a different thunderbolt device recognized to rule out it's not the egpu enclosure
I've updated the original post to add the new to market capability of using 4x 2.5GbE RTL-based PCIe cards with a link to one; cleaned up the info on baffles, PCIe cards, and using the m.2 WiFi slot; and added a link to a Thingiverse file for a Tiny5 AOC-STGN-I2C baffle.
And tables. Yeah, we have more tables.

Thx ! 
Damn - hope the next time it will be possible to unlock some BIOS-features (like TDP-down)
Already tested Promox on a M720Q with an i3-8100T (Powersave Scaling Governor and Powertop --Auto-Tune)
The consumption with two LXC (AdGuard and Uptime Kuma) is about 5-6watt - that's really low.
My ordered M720Q comes with an i5-8400T - i hope the consumption will be also on this level.

There's some information a few pages back on setting processor power consumption IIRC, might be worth a look.
Are you running your LXCs in Proxmox or LXD?

The port Thunderbolt version 3 is very attractive for Tiny from potential expansions (transfer speed 40 Gbit/s & e.g. GPU; disks; stations etc.)
Every Tbd card has 3 connectors : PCIe + tbd header + DP header.
IMHO, the M920q DP header on SB is far, far away from ideal connector and in the past it was the problem for me.
The Mather Board producers have his own Tbd Header system on the MB (e.g. 5-pin or 5-pin plus 3-pin etc.).
So now for Tiny, one can use only the Lenovo Tbd3 Cards. IMO the same problems we have with the different Tiny risers.
LENOVO PCIEx4 - TBT 3 Cards Thunderbolt Header on MB has 5-pin.
The Cards have different Tbd3 chip and compatibility depends on MB chipset (M920q is Intel Q370), also not easy to identify
- important for a lot of fmw & drv versions
Also, several ways to connect Display Port signal to Tdb3 card.
As a role, NO equivalent parts for Tiny.
On install, not such easy as NIC, pay attentions also on BIOS & OS restrictions for the Tbd3 on the same Tiny models (my big surprise).
One can found several spare parts numbers for Lenovo Tbd3 Cards:
01AJ944 | 01AJ945 | 01AJ946
01AJ968 low-profile | special 2 cables | screwed small plate for DP signal | REV : 1.0 | For M920q,
01AJ970 | 01AJ971 full-profile | different DP signal connectors | REV : 1.1 | M920t,s; P330 Gen 1/2
