I am interested in getting the spec of a machine, because I am thinking getting a similar server.

What I am mostly interested in knowing is the number of cores / CPUs / etc., the amount of memory, the speed of the CPUs, the CPU cache size, and any other detail which is important for performance.

My question is two-fold:

Which parameters should I be interested in other than the ones I specified above?
Is there an easy way to read them off the machine in Linux? cat /proc/cpuinfo reveals a lot about the CPUs, for example... What about memory (would rather not rely on top), etc?
