metal enclosure for ADT-Link R43 and GTX 980 Ti
hello please help .. i am attempting to connect  GTX 980 Ti via  ADT-Link R43 adapter to the M.2 port on  dell optiplex 9020m
i see that optiplex 3050 has been done before ( https://egpu.io/forums/builds/2016-dell-optiplex-3050m-gtx1060-6gb-r43sl-win10-pogz/ ) so i am pretty sure this will work ..
and ADT-Link makes an exposed stand for the GTX1080 ( https://www.aliexpress.com/store/product/GTX-GPU-Graphics-Card-Base-ATX-Case-PCI-e-External-Built-in-Bracket-GTX1080TI-Gen3-0/3659032_32923360862.html )
but i would like to find a metal enclosure .. please can you suggest one .. maybe Razer core X or EXP GDC v.8 ( https://www.banggood.com/V8_0-EXP-GDC-Laptop-External-Independent-Video-Card-Metal-Protector-Case-p-1121411.html ) .. is there a v.9?
maybe an enclosure with a power supply .. i can use an EVGA 650 external power supply but i would prefer one built into the enclosure.
No metal enclosure exists for ADT-Link adapters. Suggest start with a ADT-Link R43SG and can build an enclosure around it like this example:
Here's the ADT-Link R43SG without a DIY enclosure:
It has multiple power input jacks including for a Dell DA-2.
A 220W fanless Dell DA-2 AC adapter is cheap and can reliably provide slot power (75W) + 6P (75W). If the video card also have a 8P (150W) connector, as GTX980Tis tends to, then wire up a second Dell DA-2 to power the 8P using a 6P-to-8P extender + split pin to ON the adapter like shown here:
thanks for the advice .. but i am going with R43SR because a bit cheaper and hopefully easier to build around.. also I was warned away from R43SG/R3G ( https://www.aliexpress.com/item/M-2-keyM-NVMe-External-Graphics-Card-Stand-bracket-with-PCIe3-0-x4-Riser-Cable-25cm/32847514022.html ) as not performing well, although that dell brick power adapter looks more flexible than a modular power supply. I guess once i get the adapter and card working I'll try to figure out a more elegant solution for the power supply and enclosure.
unfortunately it looks like neither of those ADT-Link adapters will work directly.. they require M-key (PCIe x4) slot instead of B-Key (PCIe x2?) slot. but i think some/most graphics cards will work in a degraded mode with only one or two lanes right?
for my application (passing desktop from virtual machine to a physical monitor when passthrough of the embedded gpu won't work), i think two lanes would be sufficient .. this isn't a gaming rig .. so is there a M-key to B-key adapter? or maybe i should just cut out the B-key slot on one of the adapters?
