I just clicked it, and it shows $107 for the 8G/128G version.
But either way, I think your seriously conflating a lot of variables. Things like power draw are not really comparable unless you pick a workload and measure the perf/power, as just clamping the max frequency down, or putting less ram in it can constrain actual power draw, while still possibly being as performant as the rpi.
I don't see pricing for the case + fan + power supply on the rpi, but the 8G model is $80 for the board. So you have to find at a minimum a battery for the RTC, a case, fan, powersupply, and 128G SD for $30. But then SD isn't in the same ballpark as even the cheapest SSD with respect to longevity or at $10 likely perf either. Plus, your shit out of luck if you need 16G of ram on the rpi vs paying an extra $18 on the beelink.
In the end, the rpi is going to be a fun hack device, while the beelink is going to just work with a wide variety of software (windows anyone?) and Jeff G won't have to complain about his m.2->pcie->graphics card not working out of the box either. OTOH, if you actually need to design a HAT/whatever for some special purpose it might be easier than designing a m.2 PCIe device, or it might not be. The GPIO on the rpi might be very handy if it happens to work better than a ESP/whatever attached to the beelinks USB port driving GPIO pins.
Much of this is going to come down to how much one values their time for one off devices, and for larger production runs the fact that the beelink is just one of hundreds (likely thousands) of similar devices that can be drop in replaced when beelink has a supply issue. Particularly because there are devices that are just a $100 more with multiple 2.5G links, sata ports, whatever.
