Wireless Network Adapter
I use this computer mostly for gaming and editing video. It runs very well, and looks amazing. I have never built a computer before, and it went flawlessly. As for the name, since I built this computer on Pi day, I named it Pi. Plus I like pie.
Edit 1/30/15: Most of the parts I don't have an explanation for why I got them because I didn't know why I got them when I built it, but I went AMD because it was cheaper than Intel/Nvidia combinations. I got the CPU I did because I thought 8 cores would be cool, and I got the GPU because it was the best $300 Sapphire card at the time.
Update 5/9/13: I added a Corsair H100i because I wanted to overclock my CPU to 5.0 GHz.
Update 5/12/13: Overclocking went well, still stable at 5.0 GHz, running at 48-50 Celsius. I installed a better PSU so I can have another HDD and do better cable management. I also bought a new mechanical keyboard.
Update 2/27/14: I got a new monitor that is 144 Hertz to play CS:GO more accurately.
Update 4/5/14: Bought some ATH-M50's they're the best headphones I own.
Update 5/9/14: New HDDs for more space, of course. And some MIE2i's.
Update 6/28/14: New Headphones - Corsair Vengeance 2100's seems like I didn't get a lemon. (M50's are still best.)
Update 10/31/14: Added a SSD for faster boot up times, and everyone told me to get one, and man were they right!
Update 11/4/14: RAIDed my 2 1TB WD Blues together in RAID 0 for recording at 60fps. Update 11/20/14: Added another 1TB WD Blue for games and random things.
Update 12/15/14: Bought an AT 2020 XLR mic for Skype with my friends, I know it's overkill, but I plan to record soon
Update 12/22/14: Bought ATH AD900x Open Back Headphones along with an Amp/DAC combo: SMSL SD793-II
The prices are so high because that's what I paid for them at the time.
