Building a PC while having DDR music in the background is the most video games ass video game thing ever. My first time building my PC took around 2 hours and it was constantly interrupted by watching a video on youtube to make sure I wasn't destroying my parts. I felt quite accomplished though when it turned on the first time I plug the power into everything. I'll agree with Jeff that the one part that is a nightmare is having to plug in small dinky cables into a dark case.
