First of all I just wanted to say how much I've enjoyed stumbling onto this site in recent months. I've been building computers since I was a teen (almost two decades now), and previously it was more difficult, more expensive, and at times a very lonely endeavor. Now however the experience has changed so much, becoming streamlined and with so many options. The icing on the cake was finding a supportive community here - it's really just great.
This build was for my cousin; his first foray into PC gaming. Previously he had only consoled gamed but I was finally able to convince him that the cost of entry into the PC world was worth it.
This was my first time building with Mini ITX; previously all of my machines had been ATX mid towers. I wanted to go that route for him due to my own comfort and the flexibility of the space, but he wanted a small form factor so that it could sit nicely in his living room discreetly with his receiver or sub woofer. As it was in a tight space, temperature and silence of the build were also going to be factors. I opted for the Fractal Design Node 304 as a great choice for those requirements. The GTX 960 was selected due to coolness and relative quietness at the price point. The system has a lot of options for upgrades down the road (CPU, GPU, SSD space).
I really didn't have any problems building. Start to finish was less than two hours and I was amazed with how easy it was despite a smaller form factor. Cable management was decent. His temps under load actually BEAT my current system despite being smaller and more constricted, probably due in part to the great stock cooling that comes with this case. I would highly recommend this as a budget gaming PC or mobile gaming solution.
