It's running Arch Linux x86_64. Thus, all my machines are capable of
64 bit now. Yes, my previous CPU couldn't do it.
Having so much CPU power and RAM, I expect to use this machine for
about 10 years or even longer (except for the SSD). I used the
previous machine for 7.5 years and I could have used it a couple of
years more. But today, hardware is good and cheap and not yet spoiled
with SecureBoot, so it was the perfect time to buy a new machine.
But actually, one of the nicest things is that it is quiet. I can
barely hear it. This is absolutely awesome.
