i moved recently and don't have a TV anymore so my excitement for this kinda dwindled. the 2TB price seems like a bit of a hard sell, but honestly i expected them to be even wilder given the circumstances. personally much more excited for the Steam Frame
commenting so i remember to follow up on this later
I've been thinking about doing this exact thing too but prices for the BC250 have gone up like 50% in a few months. A lot of ebay listings are now people selling build kits with 3D printed cases and dubious power supplies bundled in for an even more inflated price.
Still significantly cheaper than a Steam Machine but if you're thinking about pulling the trigger on a BC250 you should do it relatively quick before Youtubers start making videos about the idea (again) and everything gets more expensive (again) lmao.
