Astronomical NZXT ITX Build

Today, we're taking ITX to the limit. Even though an ITX case can only fit one GPU, we think we can still make this build one to be remembered.


Since an ITX case can't fit a server motherboard, we'll be using a Ryzen processor. Specifically, the Ryzen 9 3950X, which comes with an astounding 16 cores and 32 threads. It also has a clock speed of 4.7 GHz, which makes it just about the equal, in gaming performance, of the Intel I9 10900K.


Since the Titan RTX is too big, we've chosen the Zotac RTX 2080ti AMP. This is a twin-fan module that will fit in our case, and will power any game you throw at it. Although the RTX 3000 series is coming out soon, this is a more-then-adequate card for this build.


For our case, we're using the NZXT H210i. This case is an awesome option, with a glass side panel and excellent airflow. It's made out of stainless steel and glass, both very high-quality materials, and also has air filters on all intake points. This case is also compatible with water cooling, which will be great for all the high-power components inside. Since most fan mounts will be taken up by radiators, the two included Aer fans will be sufficient.


We're going with NZXT again, and using the Kraken X63 for our CPU. This excellent cooler will make sure our CPU stays frosty and also brings in a ton of air through the radiator. Also, since the case is so small, we're also going to have a second radiator and block for the GPU. For this, we've selected the ID-cooling Frostflow 120. It will go in the place of the RTX 2080ti's backplate. The reason it's not a 240mm radiator is that there is no space for it.j


As one of the most important components, we had to make sure the motherboard was super powerful. And that's why we chose the Gigabyte X570i, the most powerful ITX Ryzen motherboard on the market today. It has two steel-reinforced DIMM slots and an x16 PCIe 4.0 slot. Lastly, it has lightning-fast Wifi 6, more than enough speed for downloads and games.

Storage and Memory

We're taking full advantage of both DIMM slots, getting Corsair's Vengeance Pro RGB 2x32gb kit, which runs at a speedy 3200MHz. For storage, we're going with the Crucial BX500 2tb SSD, which is not only high-quality but also at a nice pricepoint.

Power Supply

Lastly, we're going with the Corsair RM850 for our power supply. This will be enough to power all our components with ease. Additionally, cable management is even more important than normal in an ITX case, so the modularity will be super helpful.
