Most of the manufactured Framework-compatible accessories are skins, wraps, and expansion card organizers. Cooler Master dropped one mainboard case and seemingly bounced from the laptop project altogether. There are a bunch of cool DIY projects, a handful of which have been productized, all of them niche.
The community marketplace concept never materialized. The extensibility promise of the 16's input modules haven't materialized. The only third-party 13 mainboard that exists after 3.5 years is a cool but ultimately impractical RISC dev board/proof-of-concept; the idea that the Framework mainboard would become a laptop equivalent to the ITX/ATX standards in desktops just did not happen, and Framework's decision to start shipping a bunch of different mainboard formats means it never will.
It's particularly depressing to me that the only modular component that seems to be compatible across the 12, 13, 16, and Desktop seems to be the expansion cards, which are a fun concept but at the end of the day are just a form factor for USB-C port adapters.
I'm honestly excited about the 12 being a supposedly cheaper repairable option, although seeing this weird Desktop ready to go before the 12 is a boggling decision. I have no interest in spending $1k-$2k+ for a novel mini-PC using laptop components, in a mostly plastic case, with a bespoke motherboard crammed with soldered-on bespoke parts (even for good reasons!) that are designed to _not_ be repaired or replaced.
(By the way, why _doesn't_ the desktop use the Framework mainboard form factor? I'd be interested in a genuinely larger mainboard-compatible desktop case with more airflow, designed for a specialty Desktop mainboard but compatible with the laptop mainboards too.
A mini-ITX board that's less modular than a commodity mini-ITX board, in a mini-ITX case that isn't competitive with commodity mini-ITX cases, is such a weird choice in Framework's "keep using your mainboards" pitch. If they're going to ship a bespoke board with little to no added value when installed outside of their own case, why doesn't that board use _their own board format_?)
Hell, Cooler Master's MasterFrame line is a better execution of what I'd expect and want out of Framework shipping an *TX-compatible desktop case than Framework's case looks to be, and Cooler Master apparently worked on Framework's case too!)
And even then, the 12 is just another set of components that aren't cross-compatible with the 13. If they were selling a convertible 13 case, or even just a stylus/touchscreen display for the 13, I'd be buying it right now.
Even the 13's new AMD boards aren't exciting because I expect them to ship with the same or worse firmware and driver stability or compatibility issues that still haven't been solved on the 7040-series 13 mainboards a year after shipping them, not because Framework is a terrible company but because their support from AMD has apparently been a nightmare. I finally have my 13 stable and expect a new generation of AMD mainboard to just chuck it back into firmware hell.
That Framework keeps taking VC money just to design and ship new laptop lines when their existing lines aren't stable, _and_ ship a less-modular, less-repairable novelty in the Desktop that they try to pitch as a gaming machine—when their laptop fundamentals are still admittedly shaky, and the gaming market still doesn't seem to care for or about them very much at all—just keeps eroding the confidence that this is going to work out in the end.
