I built this PC late last year, and I absolutely love it. It's for gaming, and also is the first desktop I've had since Quake 3.
Things I like about it: 560 Ti is still very capable, VelociRaptor is incredibly fast, and the power supply is completely inaudible. The case is gorgeous and the i5 is rock-solid.
Things I dislike about it: Extreme4's MOSFETs, WD VelociRaptor makes an audible (though not irritating) clicking sound, 560 Ti doesn't overclock well (though I need to do more testing and whatnot), Shinobi wasn't that great to build in, and the monitor is wobbly and slow to start up.
Things I want to do to it:
Toss in a Tuniq Tower 120 Extreme and overclock the i5, add an SSD and more storage, grab an NZXT Hue, and upgrade my mouse/keyboard/headset. Oh, and take better photos of it. I am aware the ones I've got up look like ***.
Update 3/30/15: Replaced the 560 Ti with an EVGA GTX 970 SC ACW. Dunno how to replace that in my parts list on the new website, it seems to want me to swap out entire lists.
