This Portal cube gaming PC build deserves all the cake

Sporting an Nvidia RTX 4090 and complete with a real valve and etched portal instructions, this gaming PC is the ultimate Portal-themed PC.

Portal companion cube PC

The stupendously excellent Portal games are packed with iconic designs, from the highly cosplayable lead character, Chell, to the terrifying red-eyed glow of the sentry turrets. Perhaps the most iconic of all, though, is the weighted companion cube, which is the inspiration for this most sleek Portal PC build.

Created by Ironside Computers for YouTuber The Sphere Hunter, the PC uses a white Corsair 4000X case that’s been customized with white decals to form a stretched version of the companion cube. Inside there’s also an etched panel depicting the Portal participant instructions, and of course, there’s a shiny red Valve too.

For components, the machine sticks with an all-white theme to match the cube’s white and grey outside, and it packs quite the host of high-end hardware. There’s an Nvidia GeForce RTX 4090, Intel Core i9-13900KF, Asus ROG Strix Z790-E motherboard, Corsair Dominator Platinum memory, a Deepcool AK620 CPU cooler, 2TB Kingston KC3000 SSD, and an EVGA 1300W 80-Plus gold power supply.
