Ok, so
"Suggested CPU only block"
-CPU (not too loose or tight flowstyle)
-Pump
-Res (2x120)
-etc
"CPU+GPU"
and post popular GPU cooling blocks
you get the gist. Just post blocks for popular items.
775/1366/1156/AM2\+\3
5870, GTX2xx, 5970, etc
Chipsets are hard to call "popular" because even each board has different chipset mounting holes. For this, I can suggest the CHC-125, or CHC 122 from Koolance. Or products with a similar mounting style.
