Nowadays most cloud customers jam their racks full of absolutely vanilla (brand is mostly irrelevant) 128 vCores / 64 physical cores, 512 GByte servers for ~$18k - w/100 GBit NICs. That Sun 4500, maxed out (with 10 Gbit/Nics), sold for $70k. ($110K in 2025 dollars).

What's (still) super impressive was the 48 drives. Looking around -the common "Storage" nodes in rack these days seem to be 24x24TB CMR HDD + 2 7.68 TB NVME SDD (and a 960 GB Boot Disk) - I don't know if anyone really uses 48 drive systems commonly (outside the edge cases like Backblaze and friends)
