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 3 out of 5 by Dale1234 from Phanteks AIO / T30 Fan and E-ATX motherboard fit issues The radiator for the Phanteks Glacier One 360 T30 V2 (AIO) is about 2mm to long to fit in the Cryo Chamber. The Phanteks 120mm T30 fans (120x120x30mm) are too thick to fit in the front of the case. The max fan thickness that will fit in the fan recess is 120x120x25mm. An E-ATX motherboard (z790 AORUS Master) will not fit flat in the case. Three screws on left will go in, the middle and right screws are too short. There is a 3/16” hump on the case back panel that interferes with the motherboard right edge laying flat. I chopped and pounded my case to get high end parts to fit.

Rated 1 out of 5 by Deez22 from 30l space heater solution...I think NOT This is not a solution to 30l heat problems. You don't spend $1500+ on a gaming PC that needs another $300 and extensive work just to function. HP should offer a discount to those stuck with 30L space heaters!

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.

Rated 4 out of 5 by RVJR from Nice case so far! I just received this GT20-0230t case yesterday to build an Omen 45L DDR5 system which as of today, are still not available pre-built from HP. It came in an Omen PC box, very well packaged. It is a very good looking and solid case although probably a bit overpriced @ $350 regular price (I waited patiently until it went on sale to buy it). I already fit checked an MSI Pro Z690 Wifi DDR5 ATX board and it fits perfectly. It also clearly supports a 360mm AIO liquid cooler in the chamber. The front panel is solid but stands out from the body of the case approx 1/2 inch to allow air to be brought in by front fans (not included). The case also includes all the cabling for the front I/O board and lighting control panel. Here is what came with the case: 1. 1 x installed rear case fan (wasn't expecting that) 2. Lighting control module (RGB controller board) and wiring, installed 3. Inside LED lighting bar, installed 4. Small bag with screws/bolts for mounting the motherboard and power supply, a couple of standoff bolts, and 4 x 1 inch bolts, I think for mounting an all in one cooler. 5. Small safety/warranty pamphlet 6. CD with manuals - but for this product, there isn't a manual, just e-versions of the warranty, safety and end user license docs Missing (possibly? - not 100% clear from product description): 1. Small removable panel that covers the back of the CPU section of the motherboard (trying to get one sent out by tech support). 2. Wifi antennas - implied on website product description 3. Power supply and GPU brackets (you can see these in the HP support youtube "Removing and Replacing Parts for the Omen 45L") - apparently only included in pre-built systems. Overall, I think it is going to work out well for my PC build!

Rated 3 out of 5 by Kyle7 from Pointless, Don't waste your money. Pros + Looks Great Easy Access Design Well Made Cons - Front Glass Panel wo/ Any Gaps = Bad Cooling Intake Better Cooling Capability out of Other Cases even without the Cryo Chamber Overpriced, Best to wait for a Sale Is Not Compatible with DDR5 Motherboards to my Knowledge Overall? Decent, but save your money and buy a better case until HP gives it a needed update.

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.

Will this connect to a OMEN 25i

Asked by: bobthebuilder2
This is just a case. You would have to install a graphics card or igpu with a Display Port or HDMI output in order to connect your 25I

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.
