What hardware should I use ?

You don't need phenomenal power to self-host. Start with a machine recovered because it is too weak for office use.

If you want to buy new hardware, check first if it's suported by OpenBSD :


ARM architectures don't require much power.

If you don't know where to start, APU are quite amazing : not too expensive, small, silent, require less than 10W and well supported. Actually, this documentation is hosted on an apu2d0.

APU2 board constructor.

Take a look at bsd-hardware too and do not hesitate to contribute.

What about OpenBSD on a Raspberry Pi ?

RPi are supported from 3rd version.

Read carefully instructions as you will need some files too boot correctly.
