Welcome to my first water cooled project, Cor Leonis (heart of the lion). I haven't made any drawings for this but I have prepared some sketch up images for the log to give you an idea of what's going on, so I'll get straight into it and explain as things progress. In the following images you can see that the graphics card will mount parallel to the motherboard with the aid of a PCIex extender. I've also included the two blocks here, and the thing to note is that there will be no tubing this side of the board. All the tubing will be around the back of the board, between it and the PSU. I'll leave any more details for the progression of the project, I think it's more interesting like that. I have already played around with making some water cooling gear for the past month. As usual I start building from the inside out. The first and central part is the motherboard/GFX tray. This is only a little different from the norm in that it not only holds the mobo but also has an extra level to hold the GFX card. This is made from 4mm plate and the only thing to measure initially is the width of the board I'm going to use (mATX). The length of this piece is just a guess including all the bends for the second tier. Now before work can progress its necessary to fit the motherboard. The positions for the standoffs are taken straight off the board. The GFX card is mocked up with the extender so I can get a look at where to mark the first bend and also to measure the height and where the standoffs for the GFX card will go. Then the details are cut and filed. I usually score the bend line to give a nice, tight bend, but with this thickness a score line wont be enough. I use my little trimmer with a 3 mm bit to make a trench 2 mm deep, then with a square file, make a ninety degree 'V'. The bends are then started in the brake but completed on the bench by hand. Then the standoffs and mobo refitted. Then some standoffs are fitted to the GFX card to get a look. The card is higher than I hoped but I wanted to retain access to all the connectors under it. I may swap the standoffs for some rubber grommets and get a few mm back. That's all I've done so far so I'll be back when some more works been done.
