I am planning to build a dual system in phanteks enthoo 719 which is well designed for that type of build, i am going to use asus rog rampage omega x299 with 10920x, 4x8gb ram and rtx 2080ti with 2 onboard nvme for storage and evga x299 micro with 7900x, 2x8gb ram and 1 onboard nvme with 2070super gpu and i plan to use evga 1600w t2 psu, so how do I go about splitting the 24pin mobo, 8 pin cpu and 6+2pin pcie connectors and i will use front panel i/o from mainboard and also thinking of splitting front panel power, reset, hdd light and powerlight connectors as well so i can turn on both systems at the same time, this is mostly experimental project and i already have all parts needed that are leftover from older builds, so is it possible to split output from psu and also split front panel header connectors and the only problem i can think of is how to turn off both systems at the sametime as turning off one will abruptly cut power to 2nd system or power keeps going to turned off system as 2nd system is not powered down yet, any ideas appreciated and where can i get the splitting cables as those are the only ones i dont have, thank you for any suggestions.
