@ Nolan- These are the specs of your selected LED strips......
Specs
Available LED Colors Red, Green, Blue, Orange, White
LED Type 5050 Top SMD
Angle 120°
Lumens 50-60lm
Voltage (v) 12
!2vDc seems to be the operating voltage and you can get this from the molex connectors, the power supply/ mother board connector or the DVDrive connector, actually, it's available at many points on the mother board but these are the easiest points to access and definitely have the current to drive your LED strip.
This data you may find useful.........
