This i9-13900T machine is on sale

The industrial grade case is manufactured in Germany and has an extremely robust design using 7kg of aluminium and steel. The embedded O-ring gaskets and silicone seals protect the inbuilt system from water spray and dust.

The product uses a copper block on the CPU that connects to the external cooling fins using heat pipes. The motherboard's chipset is also cooled with a heat pipe. This design enables the product to not need air vents and enables it to be used in dusty/dirty environments. Because there are no moving parts and no air sucked into the case the product has zero maintenance and high reliability.
