Once I acquired my Nvidia 3090 graphics card, link here, I was able to begin building my new PC. I purchased a Sliger CL530, otherwise known as the Conswole, for my case and continued to use my i9-9900K CPU. In order to get the system to fit in the case, I purchased some low-profile RAM from HyperX and a Be Quiet! Shadow Rock LP to cool my CPU. I also ended up acquiring a new SFX power supply, motherboard, and SATA SSD.
In addition to simply building the PC with hardware straight out of the box, I decided to take it one step further and attempt to delid my CPU. I purchased a delidding kit from Rockit Cool which included everything I needed to modify my i9-9900K. The kit made the process very easy and I was happy with the result. However, I misjudged how insignificant the thickness of the heat spreader was. Without that extra 2-3mm, my air cooler was interfering with the RAM and power delivery components for the CPU.
It took me a bit of time to figure out how to get it working, but I eventually turned the cooler 90° to the left and sanded down a small portion of it to make it fit. I also had to completely remove the heatsinks from my RAM in order to squeeze out a few millimeters of extra clearance. Once it was turned, the heat pipes coming off the back of the cooler cleared the power delivery components on the motherboard and the sanded area fit over the top of my RAM. I also ended up having to remove most of the heatsinking components on the motherboard to get everything to fit. When I run my PC I have my CPU fan running at around 40% at idle in order keep the entire motherboard cool, even if the CPU itself is resting at a low temperature.
Delidding the CPU and then getting the cooler installed was by far the most difficult and aggravating part of this PC build. Once this was complete, it was relatively smooth sailing. I installed the PSU, SSDs, motherboard, and graphics card into the case and got everything wired together. One thing that is really nice about having such a small form factor is that the number of individual components is fairly low, so wiring is pretty straight forward. The main issue is getting everything to fit and the cables I had were not the ideal lengths. In the future I will probably replace them with some custom sleeved cables to keep my build looking as sleek as possible.
