As far as I know, there aren't any laptops that currently offer the mounting options for the 3+ drives that you would need for RAID 5 except for the Eurocom Panther 5D http://www.tomshardware.com/reviews/eurocom-panther-5d-notebook-review,3685.html
Here is a nicely made tutorial with pictures showing how to disassemble that laptop, including removing the keyboard.

That is correct, you never want to use more or less ohm's than your amp supports. (although if you have to, you can drive a higher ohm speaker, just at a reduced level)
To measure frequency (hz) you would need an oscilloscope. Measuring RMS or Impedance is very difficult unless you have some...
Using lower impedance speakers than your amp is designed to drive can cause your amp to overheat, and possibly be damaged (normally they will just shut off) this is because the speaker isn't giving enough resistance back to the amp, causing the amp to basically generate too much power.
Since...
Do you have any kind of LPF (Low Pass Filter) that you are using in conjunction with it? I ask because a good way to blow a cone is pumping higher frequencies at a higher power into a LFE.
The AMP is rate at Stereo 8ohms 90RMS, Stereo 4ohms at 125RMS, and Bridged 8ohms(what you would probably...
More than likely it has to do with the impedance on the car sub vs the home theatre sub (probably 8ohm vs 4ohm).
Check your AMP, and see what the output at different impedance is.
I personally would purchase good glass before a new body.
That is a solid body, and 10.1MP is plenty for pretty much anything, and a new higher quality lense will actually make a good difference.
The easiest thing to do is to google the computer model number, which will take you to the manufacturer's webpage for that specific machine, including all the components.
Without looking at it physically I can't say why it's stuck.
But I will re-iterate that you don't need to take it out. Get a can of compressed air and blow it out.

Easiest thing to do is get a can of compressed air and blow it out. There is no reason to take the fan out.
The fan will not come out without disassembling the entire laptop.
You will have to remove the keyboard, then as you start to lift it up, you will have to reach under and unlatch it, then slide it out of the slot.
Start at step 6 of this guide.
