5. Expected Performance Replace motherboard expected efficiency saving >50% Replace HDD expected efficiency saving >70% Remove CD/DVD expected efficiency saving >30 % Replace PSU expected efficiency saving >10%  Performance will reduce by 50%

6. Conclusions In my conclusions, Yes, power consumption will reduced by 70% but it will effect the performance to reduced by 50%.
