Here's a rehash of one of my older rainmeter skins, the Lines suite.
All of the pictured lines comes in black and white formats and can be moved around independently.
Note that you'll need to install and have SpeedFan running in order to see CPU/GPU temperatures and you may need to check and edit which gauge checks which temperature (what is correct for my laptop may be different from your system).
If you want to change the HDD meters to show space left in GB/MB, go into the config and comment out the Percentual=1 line under [MeterPercent] section, you'll also change to change the Text= line to reflect GB/MB free instead of %. Refresh when done.
