So...I think I just built my first PC...
It took me a couple of hours, mainly because I was trying to be as careful as possible...and I was trying to get some sort of order to the cables (to no avail). The real culprit of those hours was me being an idiot and not realizing that the power switch to the tower was not connected at all. I was almost sure I had damaged something or something was a dud...but man, that feeling I got when I hit the power button and the power supply, video card, and cooling fan kicked on. I think they called it a Yee-haw moment. Or a "Fuck yeah" moment.
But thanks to those that gave me help on building this (even though it only amounted to 'Does this look okay?') and thanks to this thread for existing. I needed a project to take on...and this made me feel awesome.
