After deliberating for a while [in other words procrastinating] I have decided to swap the Threadripper setup into the Cosmos II case where it will get better air circulation. While the new case is great looking and has a great cabling setup, it does not have great circulation and can get a bit warm inside. Now Coolermaster makes mesh top and front covers to replace the plastic ones, which would greatly improve internal airflow, but everywhere I've tried thus far to purchase them has no stock and Coolermaster don't sell direct to the public..... hence the swapping of cases.
My AMD Ryzen 1700X setup doesn't generate as much heat as the Threadripper and will go into the new case. It's a bit of work, but I just want to be able to run the Threadripper setup at full throttle and not experience overheating issues. Yes, the Threadripper has water cooling, and it's reasonably effective, but it's still drawing warmer air and I'm more concerned about the other components like mobo, SSDs and soundcard, etc.
Besides, the Threadripper setup deserves to be housed in a grand case, and the Cosmos II certainly is that. Moreover, there is better accommodation for HDDs and various front panel items the new case had no space for. I should have done this the first time around, but I was so enamoured by the classy appearance of the new case and just went with it.
Oh, and about the graphic card, I purchased an ASrock Radeon RX 5700XT Taichi X 8GB OC X ARGB card to boost graphics processing when I'm editing or converting videos, etc. Not sure about when it will arrive due to Covid 19 and various restrictions, but my order has been processed, so hopefully it's not long.
Anyhow, stay safe everyone and avoid the nasties going around.
