I would look for a DIFFERENT USB3.1 gen2 enclosure.
One that DOESN'T have a "captive cable" (that can't be removed or lengthened).
With this one, you're stuck with a short cable that limits where you can place the drive.

Get an enclosure that has only a USB3 port.
Then get a USB3 cable that's rated for 10gbps and long enough so that you can place the enclosure where you want.

Also, are you sure you want to spend THAT MUCH just to have a 2tb drive?
You can pick up 1tb nvme blade drives for half that price that will do the job.
I realize that's only "half the space", but I wouldn't pay extra unless you really REALLY think you're going to need it.

And then... you have to buy at least ONE MORE 2tb drive (can be an HDD) to BACK UP the 2tb drive.

When compared to the Apple alternative this is cheap. I got the smaller 500 gb drive when I ordered my iMac and regretted it so if I do this drive I will have the speed and storage at a reasonable price. Thanks for the comment on the housing though. Might get one from OWC. They have a small one with a USB3.1 port. I have a couple thunderbolt 3 cables laying around here rated for High speed transfer.

"I have a couple thunderbolt 3 cables laying around here rated for High speed transfer."

If those are truly "thunderbolt3" cables, I'm thinking they're NOT GOING TO WORK with the drive, because the drive IS NOT a "thunderbolt3" drive.
You need USBc cables, rated high-speed @10gbps.
I could be wrong.
