The victim...
Can we say surface area
It should be pretty simple to cut into appropriately sized pieces. The bandsaw should work perfectly for this purpose. The base is very well finished, but I couldnt seem to take a good photo of it without it blending into the desk. The base is 4mm thick, the surface area of the thing is 1216 cm squared (I calculate) unmodified, and the resulting SA of each waterblock (without the slots cut) will be 350-400 cm squared. Each fin is 7mm high, .5mm thick, and 37cm long. They are spaced about 1mm apart.
The height of the fan attached to the heatsink is approximately how thick the entire block will be, so I can use it to see how many pci slots I will need to use.
Also, I have decided to not use that particular retention system as I dont want to damage the PCB. Instead, I will use a twin screw design that will be bolted from the back plate to the top with some #4-40 x 1" SS screws I bought today.
I cant do any cutting today because I have lots of homework, but wait for later
