HP OMEN Obelisk review: specs, options & used prices

What this machine is

As used-market gaming desktops go, the HP OMEN Obelisk is a known quantity: standard parts, a wide configuration ladder, and steady supply on the secondary market.

Gaming desktops are defined by their graphics card first and everything else second — which is exactly what varies most between used listings of the same model line.

Tracked used listings cluster around a median of $500 (11 active listings at the time of writing).

Configurations you will actually see

The CPU options we track for the OMEN Obelisk are the Core i7-8700. These are 8th-generation Intel Core parts. From the 8th generation on, these generally meet Windows 11 requirements.

Memory options run from 16 GB to 32 GB (16 GB, 32 GB). Even the base 16 GB config is comfortable for typical office and home use; higher tiers are for specialized workloads.

Solid-state storage options include 239GB SSD, 500GB SSD and 512GB SSD.

Hard-disk listings (2TB HDD and 932GB HDD) also exist — an SSD remains the single most noticeable upgrade on this class of machine.

Drive options without a clear type in the listing (1.14TB) should be verified with the seller.

Gaming use

On a gaming desktop the graphics card is the machine, and used listings of the OMEN Obelisk vary widely in exactly that component. The configuration options we track cover CPU, memory and storage only — verify the exact GPU and its VRAM in each listing before comparing prices.

Who it fits

It fits 1080p-class gaming at used prices, where verifying the exact GPU in the listing matters more than for office machines.

The spec sheet carries the full option ladder and tracked prices; for context, browse the desktop catalog or the HP desktops page.

Verdict

The OMEN Obelisk is not exciting, and that is the point: a known quantity with a known configuration ladder.

Buy it when you need a cheap, repairable machine for its class of work, and verify the configuration before paying — RAM and storage vary widely between listings. Tracked prices span $270 to $750, and most of that spread is configuration, not condition.

Our composite LB Score currently sits at 15/100 — a score that mostly reflects the platform age — use it to compare like with like, not against modern hardware.
