HP ProDesk 600 G4 SFF Black/Silver 2019

The HP ProDesk 600 G4 SFF is a refurbished office PC with a standout 32GB of RAM and a 1TB SSD, making it a multitasking champ for basic work. Its older i5 processor is the main bottleneck, so it's not built for heavy lifting or gaming. It's a solid value if you can snag it for around $329, but skip it if the price climbs much higher.

The i5-8500 is a six-core chip that handles everyday multitasking without breaking a sweat, but it's showing its age. In our database, it lands in the 20th percentile for CPUs, which means it's outpaced by most modern processors, even budget ones. The 32GB of DDR4 RAM is a real highlight and keeps things smooth when you have a dozen Chrome tabs and a few Office apps open. The 1TB SSD is solid and middle-of-the-pack for speed, so boot times and app launches feel snappy. Just don't expect to do any gaming on the Intel UHD 630, it scored a 21 out of 100 in our gaming tests, which is firmly in 'solitaire and spreadsheets' territory.

Stacked against a new Apple Mac mini M4, this HP gets absolutely demolished in raw CPU and GPU power, but it also costs a fraction of the price. The Lenovo IdeaCentre and Dell Optiplex 7070 are its real peers, similar refurbished business boxes with comparable specs. The HP stands out with its 32GB of RAM, which is often double what you'll find in competing refurbs at this price. A wildcard is the GMKtec K12, a tiny modern mini PC that will run circles around the i5-8500 in processing power but might skimp on ports and out-of-the-box RAM.

Pricing is all over the map for this refurb, ranging from $329 to $760 depending on the bundle and seller. At the low end, around $329 for just the tower, it's a decent deal for a basic office PC with a ton of RAM and a fresh Windows 11 Pro license. Once you start creeping past $500, the value falls off a cliff. For that money, you can find newer mini PCs with much faster processors. If you're buying, stick to the cheapest listing you can find from a reputable seller.

The HP ProDesk 600 G4 SFF is a refurbished office workhorse that still has some fight left in it. You're getting a compact desktop with an 8th-gen Intel i5-8500, a generous 32GB of RAM, and a speedy 1TB SSD, all running Windows 11 Pro. It's built for spreadsheets, browser tabs, and business apps, not gaming or creative work. The integrated graphics are surprisingly well-ranked in our database, but that's mostly because the bar for integrated GPUs is pretty low.

If you need to do any photo or video editing, 3D modeling, or gaming, look elsewhere. The integrated graphics and aging processor will make those tasks a frustrating, choppy mess. You'd be much better off with a modern mini PC or a used gaming desktop with a dedicated GPU.

This is a purpose-built machine for a specific person: someone who needs a cheap, reliable desktop for a home office or small business and doesn't want to mess with building anything. It's perfect for running QuickBooks, a browser-based POS, or a mountain of Excel files. If that's you, and you find it at the lower end of its price range, it's a smart buy. Just know you're buying a tool for today's basic tasks, not a platform for tomorrow's.
