HP ProOne 600 G4, Core i5-8500T, 8GB, 256GB SSD

The HP ProOne 600 G4 is a refurbished 21.5-inch all-in-one desktop that's fine for basic office work but struggles with anything demanding. Its 8GB of RAM and 256GB SSD are both near the bottom of our database, and the integrated graphics rule out gaming entirely. At around $310 USD renewed, it's a budget AIO for light productivity and not much else.

The Core i5-8500T is a six-core chip with a 2.1GHz base clock and boost up to 3.5GHz. In our database, it sits at the 23rd percentile for CPU performance among all-in-ones, which puts it well behind modern options. That's not a shock for a refurbished business machine from 2018, but it means heavy multitasking with dozens of tabs and large Excel files will eventually show some lag. The 8GB of RAM is the bigger bottleneck. It's at the 9th percentile, which is one of the lowest we've seen. Windows 11 Pro runs okay on 8GB, but you'll feel it when you have Slack, Chrome, and a few Office apps open at once.

The 256GB SSD is also on the small side, landing at the 13th percentile. It's fast enough for quick boot-ups and app launches, but you'll need to be disciplined about storage or lean on cloud drives. The Intel UHD 630 graphics are integrated and sit at the 36th percentile, which is fine for video playback and basic display tasks but completely inadequate for gaming. Our gaming score for this machine is 7.4 out of 100, which is about as close to zero as it gets without being a literal potato.

Compared to the Dell Tower Desktop ECT1250, the ProOne 600 G4 gives you the all-in-one convenience but sacrifices upgradeability. The Dell is a traditional tower, so you can swap RAM, storage, and even add a GPU later. The ProOne is mostly locked down. The Lenovo ThinkCentre M70q Gen 5 is a tiny mini PC that's newer and more efficient, but you'll need to bring your own monitor. The Minisforum DeskMini UM880 Plus and ASUS NUC 14 Pro are both far more powerful in CPU and GPU terms, but they cost more and aren't all-in-ones. The MSI Cubi NUC AI 1UMG-015US is another mini PC with newer silicon and better port selection. If you don't specifically need the AIO form factor, any of these alternatives will serve you better long-term.

At around $310 USD for a renewed unit, the HP ProOne 600 G4 is cheap for an all-in-one with Windows 11 Pro. But cheap doesn't always mean good value. You're getting a six-year-old processor, minimal RAM, and a small SSD. For the same money, you could find a used Dell Tower Desktop ECT1250 or a Lenovo ThinkCentre M70q Gen 5 with similar or better specs and easier upgrade paths. The CAD 479 and MXN 6,299 listings are in different currencies and not directly comparable, but the US price is the reference point here. If you need an AIO specifically and don't want to mess with a separate tower and monitor, this is one of the few options in this price range. Just know you're paying for the form factor, not the performance.

The HP ProOne 600 G4 is a refurbished 21.5-inch all-in-one business desktop that lands in the budget bracket, usually around $310 USD for a renewed unit. It's aimed squarely at offices, reception desks, and home setups where desk space matters more than raw horsepower. You get a Core i5-8500T, 8GB of DDR4 RAM, a 256GB SSD, and Windows 11 Pro out of the box, plus a keyboard and mouse so it's basically ready to go once you plug it in.

Is the HP ProOne 600 G4 good for everyday office work? For spreadsheets, email, video calls, and browser tabs, it's fine. The six-core i5-8500T sips power at 35W, which keeps the AIO quiet and cool, and the SSD makes boot times snappy. But this is a 2018-era processor, and the integrated Intel UHD 630 graphics are strictly for display output, not gaming or creative work.

One thing to know before buying: this is an Amazon Renewed product. That means it's been inspected and tested by a third-party vendor, not HP. The accessories may not be original, and it ships in a generic box. The USB WiFi and Bluetooth dongles come in a small separate package, which is easy to lose if you're not paying attention.

Skip the HP ProOne 600 G4 if you plan to do any gaming, video editing, 3D work, or heavy multitasking. The integrated graphics and 8GB of RAM will frustrate you quickly. Also skip it if you need lots of local storage, since 256GB fills up fast and expansion is limited. If you want a machine you can upgrade over time, look at a small tower like the Dell Tower Desktop ECT1250 or a mini PC like the Lenovo ThinkCentre M70q Gen 5. And if you're buying for a power user or developer, this AIO will feel like a downgrade from almost anything modern.

Should you buy the HP ProOne 600 G4? Only if you need a cheap all-in-one for light office work and you understand the limitations. It's fine for email, web browsing, video calls, and basic productivity. The Windows 11 Pro license alone has some value for business users. But the 8GB of RAM and 256GB SSD are going to feel tight within a year or two, and there's no easy way to upgrade either in this chassis.

If you can stretch your budget or live with a small tower or mini PC, you'll get more performance and longevity elsewhere. The ProOne 600 G4 is a stopgap machine, not a long-term investment. For a reception desk or a spare office workstation, it does the job. For anything more demanding, look elsewhere.
