Upgrading 13' aluminum macbook (late 2008 model) II

This post is the sequel of upgrading the hardware of my 13' aluminum macbook (late 2008 model). The last post is on the installation of new ssd hard drive and the cloning of data. The new Mushkin 4Gb RAM just arrived by the door today. Can't wait to dig in:

 To change the RAM, you need to open the case by removing the 8 philips-head screws on the circumference of the aluminum case

 the green slates are the RAM

 Remove the first piece of RAM by pressing the slots on both sides. Take out the second piece in the same way

 the new RAM to be installed 

 the backcover

 put the case and screws back 

 the good thing with the 2008 13' aluminum macbook is that there are basic instruction manuals on the back of the case covering the battery and HD. The diagrams from left to right show the ways to 1) remove the battery; 2) remove the HD; 3) remove the RAM. Very pragmatic guidelines for hardware upgrade DIY 

Want to know how the combination of 128Gb SSD drive and 4Gb RAM fare in boot test? It took around 27 second to boot the OS + running 3 programs on the startup manual. Not too bad for a 3-year-old laptop. Cost? I spent $219.99 on HD and $47.99 on RAM (free shipping and no tax off Amazon), and $6 on a husky 8-in-1 torx screwdriver set, totaled at $271.98 to perform this upgrade. A bit expensive but a great lift to facilitate the processing time. Think about how much time you spend each day staring at the monitor while running multiple programs. Less frustration and less cursing at the computer comes at <$300 is a good deal for me.
