I have a spare one i can sell you if you are in the UK, I ordered two from ebay as I thought I was going to get 2 p350 tinys but only ended up getting oneAny idea where I can find a P350 Tiny PCIe x16 riser (part #5C50W00877) for sensible money? The only place that seems to have them in stock is Aliexpress, and they're gouging the heck out of the price over there

The riser for the older P330 tinys seems relatively plentiful on eBay, but I've compared these to photos of the newer one and the older riser has fewer pins on the motherboard connector so it's unlikely to be compatible.
I refuse to pay £60 / $70 for a basic PCB that probably cost $2 to make.
