"less than your application needs". Really. You will have trouble finding an example machine of any platform that runs OpenBSD that won't work. Stupidly low-end limitations: * 80386 and before won't work (this was killed probably 15 years ago. No one noticed) * 486SX won't work (needs hw FPU) (This was plus or minus a release from the 80386 termination. Few people noticed). * 16M will probably not work anymore. Last I tried, it was in swap before the login prompt. * 32M will probably let you log in before swapping. But there will be swapping. * 64M is useful for SSH tunnels and simple firewall use. Now, if you are a new user to OpenBSD, if you are wanting to make a firewall for your home, I'd say a Pentium II or P3, 256M RAM, 40G disk, and a couple decent PCI NICs would be a good starting point. COULD you do it with a Pentium 1 system? yeah, but it will try your patience, and that's generally a bad idea for new users. You really want to say, "What happens if I do *THIS* wrong", totally hose the system, and rebuild it a few times to get comfortable with an OS, and that's hard to do if a reload takes half an hour or an hour or more. If you are looking to run a GUI and a browser, um...well, I'd say at least a dual core system with 2G RAM to start with...and I recently gave up on a three core 4G system, because Firefox, Chrome, and Thunderbird would drive it into swap after a few days up-time. But this is purely an application issue; I've got a PII system with 256M RAM that's quite useful with a gui as a terminal server. Bottom end "useful" systems I've found current use for: first generation Soekris systems with 64M RAM, 486-133mhz, 2G CF storage. They make nice OpenBSD protectors for things like Dell DRAC cards on systems in data centers. SSH to the box with ssh tunnels set up, now have full DRAC access to the machines, without exposing the very soft DRAC directly to the network. HOWEVER, be aware, OpenBSD is loaded with modern (i.e., CPU intensive) cryptography. It will WORK with very old processors, but you won't enjoy it. Nick.
