I finally bit the bullet and built a PC. It was a lot of fun to do and didn't have any problems.
I use it for gaming in Windows and working in Linux. The monitor is killer for both. When Samsung released this beast I knew I'd succumb to it, and so decided to also build a nice PC to drive it.
The case is a mixed bag for me. I really like how it looks and how high quality the materials and finish are. But the "smart" fan crap I just took out. My case manufacturer doesn't need to know my Facebook account, yeesh. I also didn't realize NZXT's LED system is proprietary so I proceeded to immediately fry them when I plugged them into the MB's RGB header. Oops.
