hammertime94 - ("can't touch this", baggy trousers) - nice pics, keep it going.
According to
http://www.allwords.com/word-adaptor.html it can be spelt both ways, so don't get into a spelling flame... (petty). People resort to this when they have nothing constructive to post.
Pic 1 - you can solder directly to the pins, you don't need the plug present.
Pic 2 - best to remove the metal pieces from the cart slot removed, they don't do anything and are not needed. Hot glue - great and very useful for securing soldered wires to something else (eg mobo) so if you twist your board about or tug a wire by accident it doesn't rip the wire from the solder joint; hot glue isn't used as an alternative to soldering itself!
Pic 4 - looks like you are using a similar switch that I have been using - they work well.
Pic 5 - beware of solder blobs on your surface, they can cause shorts!
Pic 6 - fan looks fine, nice and slim. Only issue with such a fan is how to mount it in the case for airflow, without having a big hole in the back of the case for the fan itself (hence why I an using a fan exhaust).
Nice work, keep it going, and keep the pics coming!
marshallh - it is easy to remove hot glue without causing damage - score a fairly deep line in the section of the hot glue you need to remove with a craft knife and then use a pair of pliers to pry and lift it off. I have done this many, many times! Hot glue is fantastic stuff!
My soldering iron tip recently got gunked, I used my dremel with the sanding attachment to de-gunk it. Fine now.
