And then you need a case, and then you need to slap audio amplifier for speakers too, and find that one magical USB power supply that won't crash rPi under load.
Like... you could just make one, sure but it is quite a bit of work compared to just "buy a hackable box.
Oh, and some kind of supercap probably so powering it off is not crashing your FS... or build your OS to run off readonly image and only save some settings.
That is my experience from building a prototype of that

after years and years of using nearly every revision of RPi for a huge variety of things, I can safely say that the accusation of needing a supercap to prevent an 'FS crash' is absolute nonsense.
If you're talking about the degradation that accompanies any heavy use of flash NAND then i'm not sure what to tell you other than it can be mostly mitigated in software, and that it's a universal trait; RPis are by no means the only system to suffer from those issues.
I will, however, wholeheartedly agree that an RPi with a bunch of crap stapled to it is by no means equivalent to a Chumby. There is a lot to be said about the friction that is alleviated by having a standard set of hardware to program applets against, the ecosystem provided by Chumby was the whole point.
I guess for just a dashboard it doesn't matter either way, it's just running a screen; I added it coz I was worried that say background package upgrade would be stopped midway and in worst scenario, midway to upgrading kernel.

I'm not but any brand of SD card to recommend ? I was using some samsung EVO (bought off a store, not random e-bay seller) and my cluster pretty much self-destroyed even tho I severly limited writes in the first place.
They also failed in weird way where writes were confirmed but never landed on flash so the system worked till it had to remove latest writes from buffer memory... then it said FS is corrupted and after reboot it was back to previous state...1
