I do not know if I can help a lot, just a "few" words.
AMD Radeon RX 6800 XT is currently not released. The launch is planed for Nov. 18. Thus the performance (especially with hashcat) is unknown. And AMD specify the TDP with 300 W. For power supply one should calculate with a higher value, e.g. up to 460-500 W for one 3090 FE in gaming as result of peaks in (very) small time slots.
Thus one 1000 W PSU should not be enough for three AMD Radeon RX 6800 XT.
ECC is error-correcting code. ECC RAM is often used by server and (professional) storage systems. Using it or not in private area is more like a question of belief. Not every mainboard supports ECC with every Ryzen supporting it. For example one of my systems only support ECC with Ryzen not available in my country although AMD tells my cpu can.
