People find new ways of building PCs, but this one caught our attention as fitting regular-sized components in a CRT chassis is challenging.

Redditor Builds a Whole PC Inside a CRT Monitor Using Desktop Parts; Replaces Display With a Laptop Panel and Deploys Several Case Fans

Decades-old CRT display just became a fully functional computer, thanks to u/Discipline_Great, who, even though he couldn't revive the old CRT monitor, had some other plans. He says he picked it up from an e-waste, and it was already broken. So, he decided to turn it into a PC building project, which appears challenging, but not for the Redditor, who had plans to cram full-sized desktop parts inside a CRT monitor chassis.

In this case, the Redditor used a 17-inch CRT monitor chassis for his PC build. A CRT monitor might appear quite spacious, but its uneven surface makes it challenging to fit flat parts like a motherboard, GPU, or case fans perfectly. Nonetheless, the user was able to install not one or two, but a whopping seven case fans inside it. Four were used for the intake, while the other three were used for exhaust.

The user had to remove and replace the original CRT display with a 17.3-inch display from a laptop that runs at 165Hz and boasts 1440p resolution, resulting in sharper image quality. As for the components, the PC utilized the AMD Ryzen 5 7600X installed on an MSI B650 Gaming Plus motherboard. This is a regular ATX motherboard, which means easier upgradeability, but it was also difficult to install, given the space constraints.

A Radeon RX 6900 XT GPU with a triple-fan cooler was deployed inside this CRT monitor box, which appears to have decent clearance for cabling and stuff. You can see that after installing all the components, he still had enough space for the components to breathe properly. Since the chassis is decently ventilated and is equipped with several 120mm fans, the user says the temperatures were satisfactory. Overall, this was a cool DIY project, which indicates that PC building can be quite creative if you are willing to think outside the box.
