I'm about to set out on my 5950x build. I purchased the CPU from another member who was downgrading to a 5900. Not a (+/- $20) mark-up and I was very happy with the deal. I was also able to trade my 1070ti + cash with a member for an 3080 GPU. The build gets interesting from there.
I purchased a Phanteks Eclipse P600S w/ the mini ITX and PCIe 16x cable. Basically I can run two systems in one case.
Build 1A
CPU - AMD Ryzen 5950X
Cooler - Noctua NH-D15
Motherboard - GIGABYTE X570 AORUS Ultra (got this because 3 M.2 slots w/ 16x GPU and 4x for 10GB Card)
RAM - G.SKILL Trident Z Neo (For AMD Ryzen, 1 rank) DDR4 3600 4x16GB = 64GB
GPU - ZOTAC Gaming GeForce RTX 3080 AMP Holo
NIC - Mellanox 10gb Fiber
NVME - I have (3) 1TB Samsung 980
SSD- 4 drives (probably the 1TB Hynix SSD or 3 Hynix and the Crucial 2TB SSD) 2 of them are lost if I use the third M.2, no biggy.
Build 2B
CPU - Intel I7-9700K
Cooler - Corsair H60 or I have two air alternatives (Scythe Big Shuriken 3 or Noctua NH-L12S) so, TBD!
Motherboard - GIGABYTE Z390 I AORUS PRO WiFi
RAM - G.SKILL DDR4 3600 2x16GB 32GB ( acutally have 4 sticks of this, but the mini-ITX only allows for 2 sticks, shame!)
GPU - ASUS GeForce GTX 1060TI 6GB
Storage - (2) 500TB Samsung 960 or possibly the two 1TB WD Blue. Not sure I need speed here.
Extra parts may change depending on space and such.
I have (4) SK Hynix Gold 1 TB SSD, (2) 2TB Crucial Drive, (2) WD Blue 1TB Drive, (2) Crucial MX500 2TB, (2) 500GB WD Blue SSD, plus a couple of 1TB Samsung drives (860? Been awhile since I've looked). I do a ton of video editing and trying to figure out my system. Obviously the 5950x is the main editing machine, but I plan on using the 9700k as an additional render machine or as gaming machine for one of my son when he is here. Gaming would only be when both of my sons are in the room wanting to play games. Otherwise, I may use it to do other things while my main machine is rendering After Effects (can take hours!)
This project will start tomorrow when I have all of the parts. Remaining parts should be delivered today!
EDIT: Totally forgot that I purchased a 55" 4K TCL TV to use as a monitor for what we can see from a real TV. I'm planning on putting it up for review in the same space. Long story, but I have a design idea and it's basically a preview monitor.
