Hardware requirement for Using SAP ECC 6.0 (IDES)

Hi

I am planning to buy a Laptop for Learning more about SAP modules. I am planning to install ECC 5.0 or 6.0 on the laptop.

Can any one tell me about the minimum configration required for SAP IDES installation. If possible please let me know the processor to be used, the speed of the processor, the RAM and HDD required.

Also Kindly let me know from where do we get the IDES licence version of ECC 5.0 / ECC 6.0
