The dgx spark is the same chip and those are in the low 3s to 5 range for most of them depending on manu, storage config, etc. The dgx sparks also have connectx 7 cards in them to support the 200gbps networking for RoCE.

So I would expect the mini PCs to come in less than the sparks. Laptops I assume will be close in price with the addition of all the other laptop stuff.
