TLDR; Read the post. I can't shorten this anymore without clearly addressing comments that are bound to come up on this thread.
Lets break this down into 3 categories; functionality, cost, and measured performance. Note the "measured". It's italic.
Functionality: TLDR; The same as what's already available publically.
Volumio is a free, open source, buildable and downloadable OS. MyVolumio is a paid subsctiption program through which users can access premium features on the Volumio OS. MyVolumio features are not mentioned in this Drop's Overview, which leads me to believe these premium features are not included in the Primo's price.
Cost: TLDR; The case must be made of unobtanium to cost ~$300 USD.
KHADAS VIM3 Non-pro (Faster CPU, More RAM, Same Flash Capacity, USB 3.0): $99 USD
KHADAS Tone Board (Newer DAC chip, USB input option): $99 USD
Software (Volumio, compiled for the VIM3): $0 USD (See above)
Installation (the time it takes to flash the OS onto the board): $0 USD (If you do it while taking a shower)
Total no-case cost: ~$200 USD. Enough said.
Note: I'm in the process of building this exact system into the chassis of a THX AAA 789.
Performance: TLDR; TBD
I see no measurements of the Primo's DAC online yet, as I imagine (and sincerely hope, at this price) that it is custom built and not a reconfigured clone of another implementation. Specs are also not included in the Details section. We can spend a good fortnight arguing about the relevence of measurements on audiophile listening experience. To avoid this derailing this topic later, let's say that measurements are a quantified method of assessing the basic performance characteristics of a DAC. Keeps everyone happy.
Now, giving the designers and engineers the benefit of the doubt, let's assume that the lesser SBC (Asus TInker Board S) and older-chip-based DAC board on the Primo perform at par with the KHADAS setup described above.
We are left with a wonderful equation:
Same functionality + Build cost (without case) + Same (imaginatively assumed) performance = ~$200 USD
Simplifying this, we see that:
Plastic case cost (and pretty much nothing else) = ~$300 USD
I cannot express my concern any more clearly.
Pre-emption for the nay-sayers: TLDR; If you're looking at this section, a tldr isn't going to help.

nellywhadsWorst part about no measurements, is even the most basic of devices come with SOME form of specs in terms of performance. This doesn't even have much in the way of power usage or even a basic A-Weighted THD spec.. (I'd love for audiophiles to tell me to lick my finger, and test how much power is going through the thing by shocking myself, as any hint of calling for any sort of measurements is bewildering to them, and an offense almost).
How is audio still this sort of pre-historic Wild Wild West where there are no serious standards for industry practice for the consumer market? People constantly trying to buy professional interfaces, yet these same audiophiles are impartial to any measurement metrics.. *facerub*
