Finally, after 5 months of attempting to buy an RTX 4090 from Best Buy, I got fortunate with Hot Stock alerts and finally am working to install it. Here's a few quick shorts to show swapping out the parts and cleaning the PC.
Part 5 features filling the loop. You don't think there's that much liquid going in but there's a lot of radiator so yeah!
I am aware it is common to only "jump" the pump and res and not power the system every time putting load on the components but I rarely shut this machine off anyway so a few cycles are fine. All spinning rust is disconnected though for safety until the final boot sequence.
You can find the Nvidia RTX 4090 FE via Best Buy, Nvidia's store, or Amazon at: https://amzn.to/3nPb4V8
