[citation][nom]jossrik[/nom]I'd bet if you really tried, you could get 12x 60mm fans on there. The noise would be tremendous, but hey, 12 fans. 27x 40mm fans??? I have two fans on my Xigmatech and it cools pretty well, though no wheres near the Noctua or the Phanteks I been looking at. Twin towers and three fans sounds like about the limit of how insane air cooling can get, I seen pictures of how big they are getting, pretty soon you won't be able to use RAM or the top PCIx socket. Really, this is getting out of hand.[/citation]
I've never seen an air cooler that blocks low-profile RAM. i'm not saying that there aren't any, but I haven't seen any.
Also, although it is almost defintiely not what you meant, PCI-X is actually an interface usually used in some very old servers and that was based on PCI, so that would be the wrong term to use unless this is what you meant by it. What you probably should have said instead of PCIx is expansion slot. Nit-picking, I know, but still.
