some mini-itx is passively cooled, like my mini-lan-gateway-mule-server... other no.
The problem is my mini-itx use C3 CPU (2003 year)... on the new models of mini-itx is used C7 CPU.
aMule have varius problem with compilers... For example: compilation of snapshot 20070927.. over my p4 used for build rpm, configure process stop on critical error over zlib (integer expression or similar) if not force "--build=i586 --host=i586"... on new version if you compile for 586 or 486 binary use always "alien" istruction set... the problem is or amule or gcc ...
On opensuse 10.3 i have used gcc 4.2
