Nvidia has actually started to sell their own made Nvidia Cube PC that debuted at Gamescom earlier this year. Exclusive to One.de retail/e-tail shop, the Nvidia Cube PC will be available in two versions, both based on the Bitfenix Prodigy Nvidia Edition case and with Nvidia Geforce GTX 780 graphics card.
Priced at €1399, the cheaper Nvidia Cube includes, Intel Core i5-4670K CPU, 16GB of DDR3 memory and a 120GB SATA III Samsung 840 SSD while the more expensive €1499 one packs the Core i7-4770 CPU, same 16GB of DDR3 memory and a slightly larger 256GB SATA III Samsung 840 SSD.
In case you really like the design or simply do not want to build your own system, you can check out more details at the shop.
