I bought one while waiting to see if my Steam Machine reservation would be fulfilled. I paid ~$186 shipped for the board on eBay 5 weeks ago. I use an ATX power supply and NVMe that I had laying around and I printed a big case for it[0]. I seem to have gotten a good one as it has no problems after unlocking the extra CPU/GPU cores. I run vanilla Arch on mine configured to boot into Steam. The jank factor is pretty hi…
What's the performance delta? I'm waiting on a SM reservation but I wouldn't mind saving $500+ :) Is there any "jank" during active use or is this mostly a set up thing?
I think we will continue to see some performance improvements for both systems over the next coming months.
It works great if you turn the BC-250 on, play games, and turn it off.
By jank, I mean it's not a streamlined console experience like the Steam Machine. There's no suspend/resume and the idle power is quite high. If you want wifi/bluetooth, you'll have to pick a chipset well supported by Linux. (I use ethernet and a steam controller). If you want USB ports and a power button in the front like a console would have, you'll have to pick a solution for those. Carefully read over the options for power and cooling. They're very important if you're going for max performance. All the little extras add to the over-all cost as well.
https://mosfet.party/ sells a bunch of BC-250 add-ons to give you an idea of price and options.
