Waterblocks for the videocard continued

While doing this I had ordered both VGA GPU & Mobo Chipset blocks from www.dangerden.com.

The only difference is in pipe inlet/outlet placement:

Due to card components & the RAM block being in the way, it was easier to make the mobo chipset block fit the card. This I did by using some 90° elbows bought locally and making my own screw in extensions from brass welding bottle barbs. This was necessary to be able to screw the elbows past each other.

These blocks come with no form of mounting so I decided to make something simple and secure using the four holes around the GPU on GF3 cards. I firstly inset the base a little in the corners where the feet were to go. I realised It would be hard to solder them on individually as I had to heat the whole block up for the solder to flow. I got around this by soldering the feet on as one piece and then cutting out the sections in-between and shaping to finish. I then drilled the holes and tapped threads into them with an M2 tap. Finally it was retained by steal screws using nylon washers to avoid any PCB damage. This has worked fine and the block is firmly and neatly mounted without any nasty clamps or brackets. It would have been nice to just drill and tap the corners of the block, but it was a few mm to small to be able to.

Here are some pics that explain how I did it:
