Stories Of Messing Up Your First Build

Hey if anyone has any interesting stories of how they messed up your first build post it here..or if it went fine thats cool to.

I actually just started on my first build and had my first problem...20 minutes into it, I attempted to attach the cpu to the motherboard and found out a few of the pins where bent on the cpu socket and the latch wouldnt close all the way. So I had to send it back and asked for a refund so I can buy a new motherboard..they are about to get the mobo i sent back yesterday and im hoping they accept the refund.

posted this in another thread, but just finished my first build today, and i hooked up the power switch wrong, positive to negative, so i couldnt turn my pc on, i was so excited after that, turned on my pc and it went in to bios and told me to restart with my os disk, i press the open button on my drive and....nothing, somehow i forgot to connect power connectors to my hd and dvd drive :P and currently i have to open up my pc tomorrow and look at the sound because im getting none lol
