x121e using non stock wifi cards, improving the display, fixing audio jitter and silencing the fan!
A few tips that made the x121e much better for me..
Of course 8gig of ram and an ssd are cool, for those wanting to use a non bios approved wifi card without flashing a custom bios simply put the desired wifi adapter in the other mini pci-e slot (intended for a 3g card). The bottom will hold the card in place (especially if you move over the rubber spacer from above the intended wifi card.
For those annoyed with fan noise use tpfc.62 from the link below and use the smart mode when your laptop fan noise is annoying you. Take a common sense approach to using this app - most of the time leave it in bios mode (the default temp to fan speed settings intended by the designer) but when you require extra silence flip it over to smart mode. Equally when you know you're going to game or encode video or have the laptop on a soft surface switch to manual and crank the fan to 7.

For those using the x121e with an external dac/amp for music, then you may notice an annoying audio jitter every 3 minutes - this is due to the power manager app. Uninstall and the jitter will stop. Obviously you lose the battery care function and some other battery saving settings but you can claw some back by tweaking the defaults in windows 7.
The screen is a little sucky but it can be vastly improved if you calibrate the display - the defaults look terrible. Use the mp4 calibration files from the link below and follow the guide pdf. My particular x121e gives the best performance with the following settings.
With the windows calibration untouched, in graphics properties (right click on the desktop) and using the colour enhancement option in the display section.. i have red set as
brightness 1
contrast 44
gamma 1
saturation 4
blue is set as
brightness -12
contrast 40
gamma 1
saturation 1
green
brightness -3
contrast 43
gamma 1
saturation 3
obviously not all panels are the same, these values give the best compromised colour reproduction (the black levels on the panel are TERRIBLE).
