This is a multi-purpose PC made to replace my six year old i7 4790K build. Using this for gaming, photo editing, video, writing, etc. Over-bought to help keep me going for another 5-6 years without too many changes.
Built and running and finally under my desk (this is not a show piece). Need to get the CPU idle temps down from 36C, but games like Borderlands 3 and Shadow of the Tomb Raider on "ultra everything" (not ray tracing) give me about 60C at full load 1920x1080 & 100FPS+.
Still have some work to do on it, and may swap out the HSF for something beefier. I still have a ways to go before I feel comfortable with water cooling...
Just for cost comparison, in 1992 I spent close to $3000 on a Gateway 2000 Intel i486DX2-66 PC and 14" monitor (my first real PC). In 2020's US dollars, it would cost me around $5600, so I think I did okay. At least that's what I tell myself. :P
Edit: CPU Idle temps are hanging around 40C, but it never goes over 80C at full load. Added two fans to the newly vented top of the case. This decreased ALL other reported temps to where I like them, but the CPU still idles at 40C. The HSF may just not have enough thermal compound in the right places on the CPU.
Edit 2: I moved the Noctua NH-U12S to the 3700 build, installed a Noctua D15 with a good layer of Kryonaut on the 3900x, and now see consistent 37C at idle. Good enough without serious water cooling.
Edit 3: Need to update photos of the new config with the D15 cooler.
Edit 4: Photos added. Apologies for the garbage image quality. I'm not a studio photographer. :P
Edit 5: Added a couple more photos from the inside-front, just to show how tight a fit the D15 cooler is. The front 140mm fan is actually touching the top of the RAM, and has 1/4" of space from the side panel (top in the photo). Fits, though, and works great.
Edit 6: I caved and bought a glass side panel for the case. I received a credit from Newegg and applied it, so it was barely more expensive than if I'd bought it with the case. And now I have a backup metal side panel. The glass looks nice, and now I'll probably have to make some tasteful indirect LED lighting inside so I can see more of the PC. In time...
