This is the world mostly consisting of replicas of real-life GPUs and motherboards.
You can find these schematics present in this world here: http://www.minecraft-schematics.com/user/matthewstevengo/
List of motherboard pixel arts in this schematic not finished:
= Intel B85M-F PLUS (ASUS)
= AMD M4N68T-M LE V2 (ASUS)

Anyway, marking this schematic for re-rendering...
