so I have my watercooling system almost ready all whats left is to build the waterblock. so far the system has cost me under 50 canadian(including beer), I have an old celeron 900 heatsink that I think I can seal up and use, only problem would be the hold down, I need some ideas, this thing is mainly to see if I can make one and for dirt cheap. btw it is going on an oc'd celeron 900 because I dont wanna cook the good stuff just yet. Just curious to see who is into this sorta stuff.
