Delivery times on many custom things was through the roof, likely we now know why.

They don't even have the 512GB Mac Studio anymore, and it's uncertain if such a thing would exist in a theoretical M5 Ultra now. (If 128 GB of RAM upgrade is $1k, 512 would be $4k minimum, probably a lot more)

512GB of matched DDR5 DIMMs at retail will currently run you $14k-20k+ depending on speed. So I’d imagine a now-hypothetical upgrade to 512GB on the Mac Studio would be in that ballpark.
