Parts orders
All my orders came at once. Computer parts that is. That was Noctua 140 MM fans, memory kits and a replacement X10SRi-F motherboard.

I installed two of the memory kits (2x16GB)  into the two Nvidia GPU machines that are running Rosetta work, leaving them with two free memory slots. I didn't realize they had HyperX Predator originally which meant I couldn't use all 4 memory slots because the heat spreader on them is so tall it gets in the way of the CPU fan. The new kits are HyperX Fury which has a lower profile heat spreader.

I installed a Noctua fan in the front of one of the Intel GPU machines and it was louder than the one it replaced. I went back to using the original case fan. The Noctua fans run at 1200 RPM but the original fans run at 1000 RPM. I didn't try the low noise or ultra low noise adapters that the Noctua's come with because they simply slow down the fan reducing its air flow. I might try the Noctua's in the back of the case where its not so loud.

I haven't even looked at the Supermicro X10SRi-F motherboard yet.

Another build
While checking my usual PC parts online shops I noticed the Ryzen 9 3900X is on sale, so I decided I would build one as a CPU compute node.

Part Desc
Case Fractal Designs Meshify C
CPU Ryzen 3900X
Cooler Noctua NH-U12S
Disk/SSD Samsung EVO Plus 1TB
Graphics ASUS GT710 2GB
Motherboard ASUS X570-P/CSM
PSU Seasonic Focus Gold 550

I didn't buy memory. I will use the two 32GB memory kits that were going to go into the Nvidia GPU machines. The GT710 is a passively cooled card but it only needs to display a desktop.
