Xiosheng Li didn't just install his Nvidia GeForce GTX 690 graphics card in his computer, he replicated it through the medium of Lego. His 1.8 meter (six foot) long Lego replica is obviously not functional in any way - there are no GK104 cores behind the grey-brick heatsink - but it's nevertheless quite cool.
The project took 11,396 Lego bricks and three months of time to complete, costing around ¥10,000 (~US$1,640) in total. Xiaosheng used the Lego Digital Designer software to model the card, even managing to get the fan to function through the use of an electrical fan motor.
More photos of the Lego GTX 690 can be found over on the TechPowerUp forums, including a recount of how Xiosheng managed to construct the massive model.
