This is extremely interisting, because actually the path is really divided onto two thing 1/ a really DIY approach/quite cheap 2/ a more ready to go/expensive solution The netstor is even more ready to go than the sonnet 3D, because of it's PSU and 2x 8pin for the GFX, making it able to power quite powerfull GPU. and living the opportunity to swap another sfx psu since the mobo is powered by a standart 24pin atx plug.... issue beeing the price, around 900€... plus a 980 GTX, that's a LOT of money. the other road is more diy, but also as you've mentionned, a road that need to be taken seriously. the riser issue and so on, one need to chose carefully. I'm selling my Obisdian 900D case, with its setup inside, my wife want a macbook, so I've told to myself "ok, that leave me with a late 2013 MBP with I5 cpu, and dual TD2 port, so..".. and I though, why not selling my pc, go the egpu road, for a smallest (considering the obisidian 900D everything is small anyway:p).
