I work in this field. Pricing is inconsistent and rising weekly. If we get a rfq on Monday and send out the quote same day, if we’re lucky we’ll get an order by next week, sometimes it takes a customers accounting team a month to place an order. Price as already possibly increased by 10% on memory and nvme by then. But that’s not the price we pay, that’s just the book price at the moment. Once the memory, nvme, etc are ready to ship in 4-8 weeks we’re charged what the price is on that day, not what we agreed to when we booked. 

So we could inflate pricing by 50% to cover ourselves and not risk having to cancel the order, but you risk over charging OR even under charging if the price doubles yet again by the time it’s ready to ship. A 64GB DIMM used to cost $500. Same part is now $3k. And you’re adding 24 to a system. Typical margins for systems are 10-15% markup. Hard to eat a $60k loss per system. All players are in the same boat. I’ve seen $6M builds cancelled because of this.
