Well this is interesting ...

I have a DM250 that I bought a year ago that's been collecting dust because I couldn't get used to the UI/UX. It was imported straight from Japan so I'm pretty sure it's not the US model although I'll have to confirm that.

Customizing / tinkering with it has been difficult because it's a pretty niche product with not a ton of information online (at least on english websites).

Skimming this tutorial it seems like installing OpenBSD is a high-risk / high-reward type of thing. I'll have to look into further to see if it's worth it.

For those considering the US model which is listed as USD 549 [1], the Japanese one currently sells for ~USD 260 in Japan [2].

The list price appears to be ~USD 380, which is still a hefty saving compared to what they charge for the US model. There are of course software and hardware differences [3], but if it is primarily the hardware you are interested in, I see no reason not to at least consider importing one.

If the stock UI/UX is already a dealbreaker for you, the risk calculus is pretty different - you're basically bricking something you weren't using anyway. jcs is usually thorough about documenting the process, and OpenBSD on bare metal like this tends to be surprisingly stable once it's running.
