What's not to like? 48 threads, 128GB ECC RAM. Even a 480 GB SSD included. I am running Ubuntu Linux and I added 2 RAID-1 4GB drives. Expansion is limited - two hard drives, that's it, but the plus is I can lift the case as it's half the size and weight of the previous Dell. Very happy with this W/S (bought 9/2020). Warning: headroom on expansion cards is tight: My Nvidia card barely made it, is more than snug against the case. Happy enough with CPU speed, for an older CPU; multithreaded apps (eg video encoding or OCR) run like gangbusters on 48 threads.
