Is this ridiculously underpriced considering the market and availability?

I have been building similar all day online and doing theory builds and nothing comes close to the price of this. Its ugly as hell and a few off brands I am not familiar with.
But in raw power;
-9950x3dd
-5090
-64 GB ddr5 ram

Am I missing something here that's not obvious?
