NVIDIA are running a PC modding contest, with entries open until the 20th of August and community voting taking place after that. Enter NVIDIA’s PC Modding Contest and you could win US$1,000 Cash! NVIDIA invites you to build up your own gaming PC machine from the bottom up, assembled from parts you select according to your own preference. The Top 3 modding cases will win cash of US $1,000, US$600 and US$300 respectively. Plus, both participants and voters will have a chance to win GeForce GTX series card. It's open to Australians but seems to require a Facebook account to participate.
