Dual Pc Single Case Crazy Custom Build T900

[K1ng]

Ok So I have a thermaltake Tower 900 and im using two Swiftech mailstrom 300 res with d5 pump. Doing complete RGB fittings and have two thermaltake 560mm extra thick rads. Essentially this was my overkill as F*#* build as it was only for a gtx 1080 and an intel 6800k. Well now im overkilling it more by adding in a ryzen 2600 machine INTO THE SAME CASE. They will be mirrored along the back side essentailly and the loops will run into each other from machine to machine but each machine will power its own pump and res. Simple enough. But here is my issue, 8gb or 16gb of ram for machine 2 whichever ends up being slightly worse at gaming because that machine will function part time as my dedicated streaming machine and i am just curious of strictly catpuring a video and running OBS in windows 10 will really need more than 8gb of ram.
