Why an atom? There’s literally never been a nice atom machine made, they are literally sold to companies who don’t want to buy intel’s nicer power efficient chips, atleast that was the strat back in the day. A i5 540m laptop for example would have been a mid-high end laptop from the era, have the same designs and aesthetics, might even be able to find it in a similar/same chassis as the atom laptop your thinking of.

Unless you just wanna stare at the machine, don’t get an atom laptop. The Core variants from that era are literally 10-(infinity)x faster.

Who gave you the resources to let you plan out this system…

If this is for mining, son your ROI is gonna be crap I can tell you bought the most cost inefficient stuff possible cause you have a z690 board. Sacrificing 1 GPU to buy a proper platform would have allowed for them all to fit (atleast for the system to post with PCIe layout != to intel intended usecase)

If this is for compute/AI, again who gave you the money or why did you go ahead and blow that money on a bunch of relatively random hardware.
