Looking good. I would consider buying this. Fast storage array right on pci express lanes, what is not to love.
Would this ever come out as a 3.5" product with 4 nvme slots? I put together my own cases, and try to keep it slim and small as possible, it would be an easier fit. There is a trend toward small cases too. Though I am of course not sure how many others would also consider this a good option. This is obviously talking desktop usecases where storage speed is more a priority than cpu speed, where cpu's do not always have pci-e lanes to spare, 4x4 lanes is 16 lanes total which is a good fit, 32 really needs workstation boards/cpu's. Just a thought.
