Help with New Build Planning

Yep! And if you have that model you should be fine (Realtek give a lot of problem).

For the ram amount i totally agree with @SmallBarky. I have experience with 8gb on Core, totally viable for quite usage, but don’t know if in EEL is better to avoid (considering that you will probably run some docker service too).

Until they have similar spec, there is not much to worry about.
But on a no-ECC system you really want to test them with regularity with memtest (and offcourse, as part of testing all the HW)
What you should pay attention on is if the modules can be single or double side: some mainboard supports 4 sticks just if they are single density. If you have 2 you should be fine putting 2 8gb stick anyway
