Question about HP EliteDesk 800 G2 Refurbished

We have installed Ubuntu. So FreeBSD should also run.
Yes, the thing is huge, but it starts up blazing fast and runs quietly.

I can't answer that because we need the Windows 10

THE THING IS RIIISIG!!!

I don't know the system, the HP Elite Desk 600 g2 I bought came with Office 2019 pre-installed and I have now downloaded Office 365 from Microsoft. This works optimally.more I can not pass on.sorry if I was not helpful.
