Can you describe the noise.
Also go back in your machine and look around you may have distrubed a wire which could be hitting. If you have an aux fan check around it or check the cooling fan on your processor to see if anything is hitting
If your computer is making a noise, try to determine the source. What type of noise is it? Since you were recently adding parts to the computer, I would bet that you may have disturbed some cable locations and you may have one touching the CPU fan. Also, the power supply fans are famous for making a lot of noise. Is the power supply fan turning freely? Try running the PC for a little while with the cover off so you can more easily determine the source of the noise. I would be willing to bet that you will find the source pretty quickly.
that is normal. depending on the type of computer or type of ram you have the ram will make noise as it counts the ram during the boot process
