Actually, I don't think so. My 4 year old home computer does well over 30MB/second on a single commodity-spec disk drive, enough to saturate two ESCON channels of the 3090 time period, and of course server-class products do much more.  Current server-class disk arrays support tens of thousands of I/Os per second (and sometimes far higher). I think old truths about I/O performance and particular hardware platforms have stopped being accurate very long ago.

On the other hand, what I would like is a good front panel like from a 360/65 or 370/168. Modern computers lack decent blinking lights!

I had one of 'em on a 600S - didn't do much good even then - here, Moore's law has moved on without any doubt.

And the solar power array to keep this guy powered up without breaking the piggy bank!
