My first try with water cooling was in 2005 with the thermaltake tai-chi case that came with everything you needed for water cooling. I don't really have pictures of my system, but you can easily find them online. https://www.hardwaresecrets.com/thermaltake-tai-chi-case/2/
Haven't got any pics of the complete system, but for some reason, I've kept my home made socket 7 water block from the late 90s all these years. Dug it up and snapped a pic for a ghetto modding thread in another forum a while ago, might as well post it here too 😀
Basically it consists of a piece of copper sheet in the bottom, some coiled up 6mm soft annealed copper pipe, and half a roll of regular electronics solder. My crafting skills were perhaps not all that developed, but keep in mind I was an impatient teenager then, and just wanted to get on with the experiment 😁
Used it together with an extremely noisy centrifugal pump and the oil cooler from a scrapped motor cycle. Worked surprisingly well. Can't remember any specific numbers anymore, but ran an AMD K6-2 (or perhaps it was a K6-3) at quite remarkable speeds with it.
Ha... that would have been back in the day with Danger Den and co. I had a water-cooled P4 Northwood, and a water-cooled dual-CPU P3 running BeOS (since Win9x didn't have any idea what to do with multiple CPUs back then 😁). Good times.
Uff, that overclockers link really took me back. I would regularly check that, firingsquad, and virtualhideout. I think about 2 years ago I was checking the cool case gallery of VH through the archive. Good memories.
