This works perfectly.Please note:
There is a specific plug labeled Light_Bar which was used for an LED light strip inside of the original HP Omen Desktop case. I cut 2 of the pins to retro fit a different RGB setup and power button light. This is purely a cosmetic plug that will not have any effect on computer performance at all. The original light bar may not work because of the 2 pins I cut. (See image in the listing)I also removed the threads for the specific CPU cooler that was mounted. (Also listed in my other items for sale)
Other CPU coolers come with their own mounting threads.
