The short version

The OMEN MAX 45L is HP's largest gaming tower, built around a patented Cryo Chamber CPU cooling system and an Extreme Mode for manual overclocking, according to HP.

It carries a one-year limited warranty, and HP's listings do not state the power supply.

The custom build uses the closest parts in our catalog at their latest prices, including a case, cooler and Windows license where the prebuilt has one. Chips sold only to system builders use their nearest retail sibling, and memory or storage sizes not sold on their own are priced per gigabyte. A positive number means the prebuilt costs more than DIY. It doesn’t count assembly, warranty or your time.

Compatibility notes

  • The GT23-0000t uses a single 32 GB Kingston FURY DDR5-6000 stick, so dual-channel memory needs a second matching module
  • The HyperX OMEN MAX 45L GT24 model uses a Core Ultra 7 270K Plus with 2×16 GB of DDR5-6000

What reviewers and owners say

  • Tom's Hardware

    Mixed

    Tom's Hardware found this flagship prebuilt delivers excellent gaming performance and runs quietly, with rich connectivity, but it costs a steep $6,500 and reaching the second M.2 slot is awkward.

  • Tom's Guide

    Positive

    Tom's Guide found this flagship desktop delivers top-tier gaming performance, excellent cooling via the Cryo Chamber, and easy upgrades, but criticizes its very high price and excess HP software.
