So, the hubs are D792SB/D791SB, which are a reasonable set of Novatec hubs. You can get a set of those for around 100USD. So working backwards from there, 150+USD per rim and then inexpensive double-butted spokes, ends up sounding reasonable.
At one point I built myself a set of gravel wheels (LB rims) on the cheap which used those hubs. They work fine, but I've had them "ping" (pawl slip?) on me a few times and in general they don't feel rock solid like my standard Hope Pro4 hubs -- or more recently the SRAM 900 hubs I build with, etc.
I'd probably be most skeptical of the build quality. I've had to fix so many wheels with similar provenance that have been built with the wrong length spokes, etc. Obviously at that price point any corners that need to be cut are being cut. If I had to speculate, rims aren't being measured for each build -- and if the rim quality is such that there might be a couple mm of variation between runs, then always using the same spoke lengths won't be correct. So, I'd mentally prepare for to rebuild the wheels if tensions weren't right. But there's also a risk that in rebuild you discover that the wrong parts were being used, and then the value proposition degrades when you have to buy new sets of spokes. Hopefully it won't be that bad.

Have you ridden them in the meantime, I'm interested in the same wheelset. What's the weight of them? Are they any stiff? Do they set up tubeless well?
I did ride them, with gravelking sk 32 and tubes in my canyon endurace and that worked more than fine, did some gravel, mud, singletrack and it performed better than expected.
Right now I set them up tubeless with gravelking sk 42, the rubber was a hard fit but the setup was very easy. (Do remember you need a shim because the rim is asymmetrical and only a rubber didnt work for me, I used https://www.bike-components.de/en/DT-Swiss/Valve-Washer-for-Asymmetrical-Rims-p74611/) In this setup I hope to conquer the snow outside because I'm finishing my carbonda 696 build.
I didn't weigh them, I was looking for some, not to expensive wheels for my gravelbike and the choice was between some good but dull dt swiss aluminium wheels or these and so far I like them.
