Pentium 200mmx, 32 mb ram, and I think a 5gig hard drive with windows 95. I don't remember the original display adapter, but later it had a voodoo banshee put in it. We also upgraded the CPU to one of those evergreen technologies k6-2 400 MHz. Later we switched to windows 98 and a bigger hard drive. I think we must have upgraded the RAM too, but I don't remember. It was a true ship of Theseus.
Edit: also don't remember the original sound card but I think it ended with a sound blaster live with the emu10k chip.

You should turn off ssh password logins on external facing servers at a minimum. Only use ssh keys, install fail2ban, disable ssh root logins, and make sure you have a firewall limiting ports to ssh and https.
This will catch most scripted login attempts.
If you want something more advanced, look into https://en.m.wikipedia.org/wiki/Security_Technical_Implementation_Guide and try to find an ansible playbook to apply them.
