Already in place:
Since FIOS came in the area I just upgraded my network . Arris Modem and Nighthawk Router- Pushing 80 to 120 on the down side, and a solid 36 on the up.

A New Build Started:
ROG Maximus XI Formula and Core I7 9700K.
Corsair Vengeance, 32GB @3200MHz (plans to max it out at 64GB RGB @4000+MHz)
2-SSDs, WD Black M.2, Gen3 NNVMe x4 2280, 500GB each.
EVGA Supernova 1200 P2 PSU and a Noctua L9 Air cooler (Bought to bench/POST test)
Case: Thermaltake Tower 900 Black
Rad: EK-CE560

The PLAN, As time &funds allow:
When I upgrade the RAM it will be RGB, 64GB, 4000+MHZ.
More SSD's. Since I have my own massive 'Cloud' I am not worried about storage, which gives me the opportunity to go nuts with SSD's in RAID.
GPU's - I am undecided on this at the moment. But it will be NVIDIA & SLI.
Monitor(s) - Looking at ending up with 3. 2-24" and 1-32/36"
Integrating my own Boston Acoustics 7/1 speakers.
I will edit and add as time goes on.
