In decades past, this casing may indeed have housed a Nintendo Entertainment System, but these days it’s home to a decent little gaming PC.
Built by a PC Gamer reader, it packs an “Intel Core i5-4670K CPU, an ASRock Mini ITX motherboard, and an MSI GeForce GTX 750 video card”. It’s a tight squeeze, but it works!
