Sure enough, when I went to pick it up, The Cooling Shop had delivered a second Scythe Ninja fanless heatsink by accident. Bonus! Now I have one for my own machine for free :)
Just as an addendum,
Finally, del.icio.us is a fantastic tag-based online bookmark organiser. You can install an extension for Firefox that makes life great. No more annoyance at not having your bookmarks when you forget to back them up (whoops) or between PCs or browsers, and the tag organisation (which takes some getting used to) is far superior to organising by folder (think: ever wanted to put something in more than one folder, or share them easily with others?).
