Sad thing is 2400 can get you a something like a Dell R7515 with full blown EPYC 7302P 16C32T processor in it.
Big... and probably loud... I don't have any space for a 26" deep rack server either. Trying to consolidate down into less space
But yes, I realize a big portion of the price (likely) goes into their QTS OS, and another piece goes into their custom motherboards.
I suppose the TS-873AU only came out in August though, so it's basically brand new still.
I could go the path of re-purposing my Ryzen 2700 and finding a small-ish case that holds 8 HDD's and do FreeNAS or unRAID. Just a bit tricky to migrate the data over. I'm always a bit reluctant to have my storage on "consumer" hardware too though
