Hello, just looking for some opinions here on how well the EVGA B360 MB does and how it works with i7 and in Coursair 280X case.  I am working on building a new system just for gaming to replace a Z77 MB system I built back in 2012 and have been upgrading for a while.
 
I want this to be a build without going too high on the budget, I already have some parts I can pull from my older system.  This is the system I'm thinking of:
 
New Parts:
EVGA B360 Micro MB
Core™ i7 9700K
Coursair Crystal 280x case
16 Gig of memory - thinking of 2 8 Gig Coursair Vengeance RGB sticks - 2400 or 2666.
Maybe Coursair RGB 2 Fan water color like H100i?
 
From previous system that I will migrate to this new system:
EVGA RTX 2070 Gaming XC
1 TB SSD already have Win 10 installed
EVGA Supernova 750 W G3 power supply
2 TB harddrive for backups
SB Kantana I will use for sound via USB, I don't think I'll use the MB integrated sound card.
 
Some questions I have since I haven't built a system in several years.
1.  Is liquid cooling for the CPU pretty much a given now with i7 or i9 - even if I don't overclock?
2.  I don't plan on overclocking and I know B360 won't support that - so is using the i9700K a waste then and would a lower model CPU be enough?
3.  I think the B360 has 3 fan headers, will this be enough for 2 air fans and maybe dual fan water cooler/radiator?  Seems like it should be, but I haven't build a system in a while and I have never added water cooling/radiator setup to a system.
 
Note, gaming I do is a mix of RTS/Strategy/Role Playing.  I run 1080 in games, but also 2560 X 1440.  Old system did pretty good with RTX 2070 and framerate.  But turn time on Civ 6 is forever and Stellaris is running so slow, plus sometimes old system random reboots and crashes, so I think its time for a refresh.
