Check out the TASCPUInfo component, which reports the motherboard serial number and the speed of the host CPU.
TASCpuInfo is shareware and can be downloaded from: 

As for the CPU serial number, it is only available on the AMD Athlon and Intel P-III and above. The code can be found at

It is not available on most CPUs in the market today (most AMDs, P-I, P-II, etc..) which tends to make this less than useful!

TASCPUInfo is freeware. You can use the components downloadable from the site free of charge. However, the source is not available and I retain all rights over the source code.

No method you come up with will be totally foolproof. The more complex you make it, the more headaches you will make for yourself (eg: when the user does a motherboard upgrade, or adds a disk or does any one of a number of other things to the hardware that will break your code theywill be calling you about your software that no longer works!)

Ray's right. Even the CPU s/n can give you a headache (eg. if the user upgrades the CPU only or changes it).
