I am building the system with AMD 2990WX CPU which is 32 cores and 64 threads.
The motherboard series x399 is on the higher end for all manufacturers. I chose the Asus Zenith Extreme X399 which has a fairly decent setup. During the build it turns out that none of the NVidia cards would work. We tried 1070, 1070ti and others. However AMD cards worked.
The latest BIOS update was applied but it did not resolve the issue. The seller has contacted Asus support but we are yet to hear back from them. I will keep you folks posted.
Case and Cooler
I went with the Obsidian 1000D Super Tower. The latest version of this tower does not include 5.25 Inch drive bays used for DVD drives. Which is a good thing. The older version probably had drive bays and hence it was not considered by anyone for building super tower. I do believe Phanteks has an equally good Super Tower.
The issue we faced was this. There are two trays provided for holding fans. One is 8 x 120 mm and the other is 3 x 140 mm which makes it very odd. The only Cooler we can use today with AMD TR4 socket is Enermax liqtech II 360 mm which is a 120mm x 3 fan. The mismatch of size resulted in us placing the 8 x fan tray on top to hold the radiator fans. This tray would have been useful in front intake with all 8 x fans loaded. Now we have the 3 x 140 mm tray in front.
I could not find decent fans in the assembly shop at the time so I am stuck with “Gamer” fans where I leave the RGB lights disconnected. The case is huge and rightfully so, the motherboard overheats since it has so many components built-in. It requires heat exchange but the combination of what is happening does not leave us much choice.
I will post pictures later of the setup. I might have to replace the mobo if it does not work with NVidia cards. While I dont mind getting a Vega, the rest of my cards are NVidia and I will not be able to use them. This will add to the cost.
Thank to Bizgram @Simlim level 5 for helping build such a massive and complex system.
