This was my first watercooled build, my second build overall, and first build in 7 years.
The goal of this build can be summarized as "elegance in efficiency" - i.e. efficiency of space. I wanted to cram the absolute beefiest rig I possibly could in the smallest chassis I could with the best cooling I could.
My end goal was to be able to accomplish a silent, small gaming rig capable of driving any modern game at max settings at 144 Hz. You'd think that these three would be impossible to do all at once, but it's never possible until you treat it as a challenge!
After many tens of hours of thinking, I had finally planned out my custom loop: 1x120mm + 1x240mm + 1x280mm. That's basically the equivalent of 2x360mm in surface area. Try that in an mATX case!
The beefy watercooling setup is handling a 7900X @ 4.6 GHz @ 1.115V - a great voltage for that overclock! Both my GPUs are running at +175 core clock and +500 memory clock.
The CPU idles in the 35-50 range, loads at around 60 in gaming, and around 75 in the more intense AVX Prime95 tests (which are not representative of a real workload). The GPUs idle around 40-45C and rarely go above 50C. Not the best temps, but I've optimized for silence: the fans and pump don't even turn on when I'm gaming - even in my most intense games. They sit at 0% (which turns out to be about 500RPM). (They do turn on when doing Prime95.)
Every piece was meticulously picked. The 7900X may be inferior to some of the TR processors for productivity, but for my particular uses, it nails the sweet spot between single-thread and multi-core. It's literally the perfect processor for my workload.
The X299M is a phenomenal motherboard, and is the centerpiece of this build. It was a prerequisite for making my computer "small" - i.e. mATX. The board handles my overclocks just fine, doesn't have a shroud over the VRMs (so they stay cool), has an excellent BIOS GUI, the latest and best Intel WiFi card built in... I could go on.
The 32GB RAM @ 3200MHz was a solid choice: The 7900X's ringbus architecture is similar to Ryzen/TR's Infinity Fabric in that communication between cores is reliant on RAM speed. The 14CL was low enough to keep me from moving to RAM with higher frequencies (but also higher CLs).
The 850 EVO was salvaged from an older laptop, and provides me with a large, fast secondary storage medium. The 960 EVO is my primary drive. Windows boots in under 3 seconds, and programs are lightning-fast to start. (The 960 PRO was in the running, but the difference in price simply did not justify the unnoticeable difference in RW speeds.)
The GTX 1080 Ti's are the best gaming cards on the market today, and scale quite well with SLI. These are what enable me to go from 90ish FPS to the full 144 my monitor can offer. They are tied together with Zotac's unique-looking SLI bridge, which has this beautiful geometric texture.
The PRIME Titanium: This beautiful PSU is, strangely, my favorite component of the entire build. It's plainly obvious that SeaSonic went all-out in the construction of this PSU. It's the most lauded and praised PSU in the history of PSU's, hailed as a "technological pinnacle [...] mythical" by AnandTech; the ultra-rare perfect score of 10/10 from JonnyGuru; and receives KitGuru's absolute "highest recommendation."
Ensourced cables bring the whole build together, and are the highest quality cables I've ever seen. They look just as stunning in real life as they do on Ensourced's website.
The Evolv mATX TG is a stunning case that is having its front and top panels CNC'd with a Deus Ex themed design for better airflow.
