For example "3.2TB Enterprise NVMe Mixed Use AG Drive U.2 Gen4 with carrier" is $3,301.65 each, and you'd need 10 of those to match the Oxide storage spec -- already above the $30k total price you quoted. Similarly, "128GB LRDIMM, 3200MT/s, Quad Rank" was $3,384.79 each, and you'd need 8 of those to reach the 1TiB of memory per server Oxide provides.
With just the RAM and SSD cost quoted by Dell, I get to $60k per server (x16 = $960k), which isn't counting CPU, power, or networking.
I agree these costs are way way way higher than what I'd expect for consumer RAM or SSD, but I think if Oxide is charging in line with Dell they should be asking at least $1MM for that hardware. (At least compared to Dell's list prices -- I don't purchase enterprise hardware either so I don't know how much discounting is typical)
Edit: the specific Dell server model I was working off of for configuration was called "PowerEdge R6515 Rack Server", since it was one of the few I found that allowed selecting the exact same AMD EPYC CPU model that Oxide uses [1]
