First time build.
Recently, I built this computer for my part-time work (assistant professor) and casual gaming. I needed a PC to help me compose my presentations using video/picture editing and thought i7-3770 would be a nice choice. Along the side of gaming, I enjoy MMORPGs and thought the keyboard and mouse would be nice to add on.
Cooling - I found some nice deals and just decided to go with air cooling for now. The pair of noctua fans I got for $10.00 for the pair and the NH-D14 was discounted at the time of purchase. I figure I can use the fans later when I upgrade to a water cooling system.
The case, NZXT Switch 810, and the power supply, Corsair 750M, were both free from my brother. Can't really argue if it's free.
