i'd be inclined to say get a nvme m.2 drive, as you'd benefit from the increased speedsSATA vs PCIe SSDs - big difference? If PCIe is quicker I'd prefer 256GB PCIe for the OS/scratch rather than 2x256GB SATA.
in my experience, wd. but as always, ymmvHDD brand - Toshiba/Seagate/WD - any difference?
more than enough300W PSU enough? How close is that to the actual expected consumption of the system?
