I think this is a good idea. There are many many worklogs spreaded all over the board. From "simple" things like the Aquasphaere ( wie schreibt man das teil?? ) to very BIG projekts like my Silverstone LC17 HTPC

ROFL
I think it would be also interesting to have an "worklog" link on the AC mainpage where interested users can see what some AC users have done with all the Stuff
Btw. a little history could be nice too .. from some "oldschool" projekts with all the old stuff to the newest hightech watercooling stuff.
