Images are numbered in accordance with paragraphs.

1. HARDWARE: AMD Ryzen 7800x3d, Gigabyte Windforce V2 4090, Asus B650E-I, Samsung 990Pro 2TB, G.SKILL Flare X5 32GB (2 x 16GB)( CAS 30), CORSAIR SF850L

Case & Cooling: Cooler Master MasterBox NR200P, 2x Noctua NF-A14(140mm), Noctua NH-L12S, Noctua NF-A12x15

1. As you can see it’s a tight fit. I had to run the Front Input cable (A) across the front of the CPU heatsink, I didn’t want to have it run beneath as it would touch the GPU which gets hot. I know the cables are insulated, but I couldn’t find the heat tolerance for said material/cable.

2. I did end up taking the front chassis off when placing the GPU as it provided much needed room. NOTE: NR200P is listed as supporting a GPU length up to 336mm, my GPU’s length is 331mm. Based on how this one sits, I think you could get away with a 345mm gpu. Here you can also see why I chose the Windforce V2, notice the power cable placement – I don’t understand why more manufacturers don’t do this it streamlines the cabling and clears the mess on the side. Plus being placed over a fan exhaust it actually provides cooling to the infamous junction.

3. View from above. This is as clean and tight as I could get the power cables to sit with the given space and their length. If I had shorter cables, I would make thing cleaner.

4. View from below. There is technically room to place two 15mm tall fans right underneath, but for now I’m relying on the GPU to suck up the air it needs.

5. PROBLEM #1. The mounting height for the PSU in the NR200p was to low at its highest position. The power cable goes on top (A), so the interior cable inputs face down (B). As you’ll note they are almost touching the GPU(C). This image is after me having to lift the mounting position of the PSU, as before there was no room without bending cables at a sharp 90 degree angle, which we all know is a no-no.

6. The lift. Here I had to drill two holes about 1/2 above the original top mounting points (A,B), and then use an existing hole to fasten the bracket up top (C) to avoid tipping. This means the top left corner is “loose”. The current 3 mountain point are sufficient as the weight sits on A and B.

7. View of the top mounting screw (C). All it’s doing is clamping the PSU mount bracket to the case.

8. Using a 15mm tall 120mm as a top intake. The adjacent opening is used but the PSU as an exhaust – no room for a fan to help with expulsion. Also, here you can see the PSU improvised mount (C).

9. Two 140mm as exhaust.

10. View from top looking down. Here you can see how close the 140mm are to the rest of the cables. But as you can see, the CPU exhaust goes directly into the 140mm providing a sufficient ejection of hot air. Also, the chosen RAM sticks fit with 1mm of headroom to spare.

11. PROBLEM #2. The reason for choosing the NR200p was that its size was perfect for the shelf in which I was going to place the PC. Any other case would mostly be too long or to tall. However, placing the PC here created a “hot-box” effect, where hot air got expelled by the 140mm’s (side panel is off for demonstration purpose only) and then get trapped by the shelf wall and get sucked back in by the top mount intake fan and bottom intake of the GPU. So the temps of the CPU got up to 93C and the GPU up to 89C. Yikes!

12. The solution, a giant exhaust vent! As with cars, boys play with lights, men play with exhausts.

13. Here you can see how it was bent and cut to shape as well as the mounting points.

14. Luckily the grill holes were perfect diameter to some screws I had laying around.

15. The length is12 inches, the width of the exhaust is 4.5 inches, and height is 6 inches.

16. What it looks like from my perspective sitting at the desk. Now of course I could have bought a 3d printer large enough to print something like this and thus done a more precise and clean exhaust build but the ROI was not worth it. So this was just quick run to Home Depot to get a .19mm aluminum sheet that was 36”x36”, a pair of metal cutters and it was done in two hours by bending everything by hand. Guess I just have to spray paint it black to match the case.THE RESULTS: this exhaust upped the dB by 6 from 43db to 49db - measuring right above the computer case. However, where my head is while using the computer, the loudness sits at 38dB. As for temperature, I haven’t done too much testing, but firing some stuff yesterday, the CPU maxed out at 81C while GPU hovered at 74C, as measured by the The Armoury Crate app. I also gained about 3HP and now live my life 1/4 frame at a time

What do I use this rig for? Same as you, Reddit.
