well. i thought about it some more, and went ahead and ordered some metal. i am planning to make a similar design (spiral) to the waterblock picts i posted before.
Puzzdre: yea, i hadnt really though about that... im just gonna forget those - i dont think that they will help all that much anyway.
because of my total lack of skill and lack of experience in doing stuff like this, i decided to drill all the way througha 1/4" copper sheet, and then glue/solder on a 1/4" copper top and 1/8" copper bottom. i was thinking of using arctic silver adhesive to glue these together, anyone done this? it seems like i might get better thermal conductivity than with solder.
so anyway, i hope it all works out.
oh, i decided to make some ramsinks too for my video card. im gonna get some of the 1/8" bar and cut it into little ram-sized bits and then drill holes in it and put 1/8" copper rods through them, solder/arcticsilver glue like 8 of them on and then sand the bottom down. seems like it should have some pretty good surface area. sound like a good idea? (if not, i spend a whole of three dollars on the metal rods

)
Nick C: i see about the block problem with the zif socket. i ordered 2 1/2 stuff anyway, just to make sure i have enough. i will be careful to take that into consideration though - it would really suck to forget and then have your block not fit.
anyway, thanks for the input everyone.
