Hi all, new to the forum but decided to post my new build thanks to all the great tips I found going through this thread to get all the right parts. I took some of the components like HDDs and RAM out of my older 450D ATX build and placed them into the new 250D. And voila! Love the compactness of it all.
I went with the MSI 1080 Ti for the color skim and because it fits perfectly in the case, just enough space for the fan blades to not touch the side panel dust filter and it's pretty quiet. With this setup I could even fit a 200mm front chassis fan without the metal grill.
During installation of the radiator I recommend screwing it to the upper holes as it will prevent the 120mm from pressing against the motherboard, I could actually use all the screw holes to fix the fans to the radiator but decided against screwing the bottom parts to make it easy to remove them without removing the board. I could easily swap them in the future if I decided to go with full RGB even if they are a little bit thicker. I also didn't have to remove the middle back plate supporting the bottom part of the radiator. I recommend placing the 120mm as outtake to suck the hot air out of the case, after some testing I gained about 10°C vs intake.
I'm using a Coolermaster 80mm silent fan to suck hot air in the back, much cheaper than the Noctua NF-A8s and it perform well without being noisy, also matched the overall color scheme. I'm getting a second one after making sure the first one performed well.
Overall it's been a fun experience making this build, most time spent finding the best ways to route the cables to make it nice and clean. I love that its so small and you can easily move it around and put it on top of your desk instead of under. Cheers.

Room temp without aircon around 23°C. GPU under load around 70°-72°C with the CPU hitting just below 60°C, GPU fans ramp up to around 60%-80%. Using MSI afterburner with custom fan curve and using NZXT CAM software in performance mode to regulate radiator and front chassis fans. You can hear the fans under load but it's still pretty quiet. Absolutely silent on idle, around 35-40°C for CPU & GPU.
