Description

I wanted a rig that could be used for programming, machine learning and AI research, as well as some light gaming. In addition I needed some media storage for my collection of CD, Blu Ray, DVDs. Some secondary goals were to have a great looking system for my home-office, and to have a small monitor inside the case to be used for displaying system info such as temps, CPU utilisation etc. I use Linux (Ubuntu 18.04 LTS) rather than Windows or Mac OS/X, so was slightly more careful to ensure that drivers were avaiable for all of my harware choices.

My case was the stunning Cooler Master Cosmos C700M. This case reminds me of the Star Trek Romulan Warbird, whose combination of beauty and intimidation were exactly what I was looking for ;) It also comes with a GPU bracket that I thought would allow me mount a 5 inch OLED panel - more of which later. The case itself was super-easy to build in. There is lots of space, it is very configurable, and despite some things I had read and seen online, I found cable management to be excellent. One minor snag I encountered was to do with my choice of motherboard and CPU AIO. The ASRock X399 Taichi motherboard has 8 RAM slots, 4 either side of the CPU, however the side-attached coolant pipes of the NZXT Kraken X72, block the inner-most RAM slot on the right side of the CPU, effectively eliminating 2 RAM slots, as they have to be deployed in pairs. Fortunately for me, I only intended to populate 4 of the 8 RAM slots initially, so not an issue for now.

I was new to the PC case RGB scene, and had not appreciated that RGB and Addressable RGB were incompatible with each other. My case has ARGB LEDs built in but my motherboard cannot drive ARGBs, it turns out, so no motherboard control of the ARGB case lights with the X399 Taichi, which only has RGB headers.

The CPU temperatures were initially a little on the high side but I managed to reduce them by 8 degrees Celcius by swapping out the NZXT fans of the Kraken radiator with 120mm Noctua fans. With the AIO radiator front-mounted I could mount the Noctua fans such that it was impossible to see them in every day use. Whilst the Noctua fans are the best performing and quietest fans I have ever used, that light-brown colour would have destroyed the design aesthetic if they were visible.

Lastly, I wanted a small OLED panel for inside the case, to be used for system monitoring. OLED rather than LCD to minmise bleed from the backlight and to ensure high contrast with super-black blacks. The one I chose was a 5.5 inch, 1920x1080 pixel OLED panel. The MSI GPU card I used can drive multiple displays simultaneously, so I drive my main display from one of its 3 Display Port sockets, and the 5.5 inch internal display is driven via HDMI. The display is powered using one of the external USB 3.1 sockets at the back of the motherboard. I simply drilled holes in the GPU-mounting assembly that Cooler Master provides with the case, and attached the 5.5 inch display using the standoffs provided with it. I also had to remove the GPU-bracket end-plate to prevent the GPU bracket from touching the GPU-card which I mounted in the top PCIe slot.

Overall I am pretty pleased with the way the build turned out.

Great Build!

We’re did you get those white keycaps for your Drevo Keyboard?

I used Corsair keycaps from Amazon.co.uk. The remaining black ones like the spacebar, are positions where they would not fit. All others fit perfectly. I particularly like the font on the Corsair keys.

Very nice! What software are you using for system monitoring?

I am in the process of writing something myself in Python, using the psutil module, as it gives access to almost all of the underlying raw data I need. I thought about just using the Windows-based GUI monitoring apps provided by the motherboard and GPU vendors (ASRock and MSI), but with those I would have almost no control over the visuals, and in any case they were designed for a larger screen.

Writing it myself means I can have real-time graphs of temps, CPU usage, fan-speeds etc, as well as newsflashing important system messages. I also get 100% artistic control of the visuals!! I will upload some pictures of it once it is in a presentable state.

Very nice, clean build. Love that case, really is a beauty.

RGB issues can be pretty annoying with all the proprietary stuff. If you use different companies it's easy to end up with 4 or 5 RGB programs on your system. Thankfully they don't use many resources, just annoying.

Regarding the ARGB, if you wanted better control over your phanteks halos (I'd check compatibility), you could try their Digital RGB LED Starter Kit. Lets you change settings via controller, no software required. I use a controller for my AIO (deepcool) because I prefer their settings to the ones on the mobo. ASrock Polychrome isn't all that great imo.

If you wanted to do more w/ your case lights, I believe Coolermaster also has RGB controllers but I haven't looked into them.

One last thing, if you have trouble w/ your AIO mounting you could try the same one I went for. It's the Deepcool Castle 360ex, which gives mounting options. Can mount it with the tubing on any side, and since you can adjust the center image orientation, it won't look out of place. Solid AIO too, works very well even with it's included fans. Would allow you to populate all your ram slots if you ever needed it.
