update for you all,
after some change in personal circumstances back and forth and attempt to sell my P350 tiny. i managed to keep it and gain a dell precision laptop with Quadro T2000, so had no need for the T1000 in the Tiny. . . so I ordered a similar card from Qnap, as my budget was quite low, and grabbed a QM2-2P-244A card to replace the gpu in my P350. as the P350 doesn't offer bifurcation support, you do need the card with the PCI switch on board.
few notes on instal, the gpu backplate from the tiny's screws do not line up with those on the Qnap card so you end up mounting the backplate to the chassis but not the card, the LED's do lineup with the minidp ports though so thats nice.
as the backplate is not attached, and the pci card is only 4x i think (short) it doesn't lock in to the pci slot either, so you need to find other ways to secure, my temp solution till i can get some brackets printed up is a rubber band around the card.
the other thing to take note of, is the card is longer than the Quadro GPU's so you need to remove the BT antenna bracket to fit the card in, you can then unstick the sticky tape holding the antenna to this bracket off and shove it down the side of the pci slot (im sure there is more elegant options)
all up and running nice now with 3 2tb drives and a 512 for OS, plan to replace one 2tb and the 512 with 4tb drives at some point in the future and move away from server 2022 bare metal that im running right now to a virtualised environment.
stoked to have a 1ltr sever with 8cores, 16threads, 32gb ram and 4 nvme drives now, just wish it had thunderbolt onboard also, will consider looking into one of the qnap cards that offer faster ethernet Aswell as the nvme slots down the line.
