Recently I have managed to build my little deep learning workstation 
And I wanted to share my experience with you. So I wrote a blog post where tried to cover all aspects of building such a project including:

reasons why I went for this
parts selection
hardware installation
software and CUDA installation
my current workflow

I feel like this may be helpful for enthusiasts like myself who think about own GPU-accelerated machine:
