Rated 5 out of 5 by Sydney A from Beautiful and silent with great airflow This is a beautiful case, easy to access on both panel sides with clear cable routing capabilities. Having the cryo chamber separate allows plenty of space for air circulation and larger graphic boards. The whole assembly is nearly silent, and although there are not a lot of built-in ports, there are enough for most gaming builds.

Rated 4 out of 5 by G Thomas from Huge Improvement Over Omen 30L Case I swapped my existing HP Omen 30L GT13-1094 system into this case, replacing the existing 120mm AIO cooler with a 360mm AIO, and added 3 120mm ARGB fans to the front of the case. As noted in another review, this case doesn’t include the wifi antennas, which are different than those that came with the 30L. I managed to reuse the 30L wifi antennas with some creative use of black cloth tape, but at this price they really should be included. In terms of thermal performance, my 5800x now idles under 40C and peaks at 78C during stress testing, while the GPU idles under 30C.

OMEN Gaming Hub does not control the rgb strip light or the front panel light. Are there any drivers that can be used to make this work?

Asked by: alex14
The RGB Control is not being controlled by HP Omen. RGB strip doesn't light up and the front light just blinks white. I plugged the RGB strip into Corsair iCUE and it lit up and I can change colors. It's crazy that they ship this case without any drivers to make the lights work. I can't find anywhere to download them and OMEN Gaming Hub does nothing.

I'd like to build a DDR5 custom build (not currently available through HP) using this 45L case. I'd like it to look like your prebuilt offerings, what brand and size of RGB fans should I use for the front and back and for a cooler in the cyro chamber?

Could I use the front panel from the 45L case to replace a broken front panel on a 40L case? Or is the 45L’s front panel too big?

Asked by: Roy Cota
No, the 45L front panel will be too big for the 40L.
