This! When you are using OpenBSD, and wonder how a particular piece of the kernel works, you just open the source code, read it, and you can usually have a good idea of the inner workings with some days studying it. Trying to do the same thing with linux, you would need months to grasp any idea of how it works. Linux is developed by thousands of people all around the world at the same time. OpenBSD on the other hand is developed by a few power developers, which gives the code a unique consistency and readability.

Just use Debian GNU/Linux minimum-installation without desktop environment. I doubt you're much faster in studying the OpenBSD kernel compared to the Linux kernel. I'm also not sure if some days are enough for both of them.
