Well fear not, you will be hard-pressed to get much easier than this......
This block was made with a hack-saw , a cordless drill, and a M5 tap. some solder for the gasket\o-ring and some goop.
the two plates are Aluminum (anodized), would you believe that...
anodized no less.... hehehe
absolutely nothing as far as inside geometry.... just a thin flat water cavity.... obviously the 2 bolts sticking out, for attaching it to a P2 233Mhz cpu, ( giving a clue as to its age there)
this specimen is still very much alive, though not in use right now. ( for obvious reasons)
It pre dates to the late 20th century and was a one-of
performance..... well all I had to go by, at that time, was some extremely crappy Pentium heatsinks, This was long before all these nice oversized heatsinks came into existence, so obviously I was absolutely ecstatic by how well it performed... and from there the reason I'm here now, a complete and utter noob when it comes to high performance CPU heatsinks.
I guess I just never felt the need to get a heatsink-upgrade anymore...
Now all I need to figure out, is how to get the 3 year warrantee on a new CPU, without getting the fan and sink along with it....
