I've built more than a few custom gaming PCs in my lifetime, and though I've always been happy with how they turned out, they have nothing on some of the enthusiast builds found online.

The latest custom gaming PC that dropped my jaw comes from Reddit user OkDebate6649. Earlier this week, they shared a gallery of images of what appeared to be an '80s-era Macintosh, complete with a CRT-esque monitor enclosure and attached keyboard.

The builder states that they've "never really played games on a PC before, so I'm really excited to try some modern games." Is there a better introduction to PC gaming than with your own custom LEGO build?

What's inside of the LEGO PC build?

The main focus here is, of course, the actual PC. As OkDebate6649 notes, it was designed in a modular fashion, which allows it to be used with monitors they've built out of LEGO in the past.

Not only is the exterior retro-styled case made of LEGO, but so are the internals. Inside the rectangular LEGO PC is an AMD BC250 board that's akin to a PS5's APU. It has six Zen 2 cores, 24 RDNA 2 Compute Units (CUs), and 16GB of memory.

It's able to deliver performance similar to a GTX 1660 Ti, and it's most often associated with DIY builds like this for 1080p PC gaming.

AS OkDebate6649 points out, the BC250 board is notably a hot ticket, so some extra cooling effort was required. They used Phase Change Material (PTM) on the board's APU, with dual fans covering the board's heatsink.

On the case, two fans push air in, and another two push air out. It's revealed that the PC "runs stably at around 75°C with the APU overclocked and running "some Steam game demos." While idling, temperatures fall to about 45°C. Not bad at all.

Wiring channels and harnesses all appear to be LEGO-related, and the front panel, made to look like a retro Macintosh, has a fake floppy drive, Apple logo, and actual working ports.

Around the back are more ports, a power toggle, and PSU access. Getting inside the PC appears to be quite easy, as custom LEGO panels are simply pulled up and away to reveal the internals.

Windows Central's take

LEGO PC build with BC250 from r/pcmasterrace

Countless custom PC builds get shared online every day, but it takes something truly special to stand out. Earlier this year, I covered an RTX 5080 PC built entirely into a Victorian-era radiator.

Although this new LEGO build likely didn't take as many power tools to complete as the radiator build, the levels of craftsmanship and engineering are undoubtedly impressive and show off some true technical skill.

LEGO was never meant to line up with PC hardware dimensions, and the fact that this custom build is so clean is really what pushes it over the edge.

Considering you can often buy an AMD BC250 board for less than $150, what's stopping you from doing something similar?
