Siren Vortex SnowMacho GeForce RTX 3080 Gaming PC
Seems like a half decent deal. Saving a couple of hundred off the retail cost of the components. Not bad seeing you don't have to source components and build.

Personal opinion (for comparison): This seems to beat the TechFast deal for $2144, as this includes a larger SSD (1tb vs 500gb), Liquid Cooler and 850w PSU. If you added these components to the TechFast deal with discount, you would be looking at $2,371.00. You could double the RAM and add the WiFi card to the BPC deal and come to $2,367.00. I'd probably chuck the extra drive (3TB) in for $95 for the extra storage.
I wouldn't make my 3080 live in that case.
