The author designed 6-inch and 12-inch server racks using bent metal, adhering to standard mounting hole dimensions derived from 19-inch rack specifications. The assembly process relies exclusively on screws and nuts for component attachment, with a powder coating finish selected to avoid the surface preparation required for anodizing.
Manufacturing costs for a 6-inch rack with six shelves total 20 000 ₽, a price point comparable to Chinese-made alternatives. The author notes that existing commercial solutions, such as those from DeskPi, often utilize proprietary standards, including threaded holes instead of standard square server nuts and slight variations in width.
Separately, the author assembled a home server for local AI model execution to reduce cloud dependency. The hardware configuration features a 1-kilowatt power supply, two Tesla P100 GPUs providing 32 GB of total VRAM, and a 28-thread Xeon processor. The system achieves speeds between 10 and 50 tokens per second depending on the model.
