I have been running a watercooled system for quite a while now and I haven’t seen any setups like mine. I am attaching a couple of pictures. Notice that I drillid holes in the case for the connections to the radiator. I hope they are of interest to you.
I was also wondering if anyone has liquid cooled a hard drive. I was thinking I could do this by modifying my hard drive heatsink(you can see it in the picture). I am using an IBM 36LZX 10K RPM drive and it can get hot.
