Snapshot
The 30-Second Version
Great processor, frustratingly small RAM and storage. It's a capable office PC that Dell crippled with 2020-era specs.
Pros & Cons
Pros
- Ryzen 5 8500G with Radeon 740M is genuinely fast for a slim desktop 70th
- Compact 12-inch tall chassis fits almost anywhere 65th
- Windows 11 Pro out of the box, no upgrade fee
- Solid port selection with DisplayPort, HDMI 2.1, and 7 USB-A ports
Cons
- 8GB RAM is borderline unusable for multitasking in 2025
- 256GB SSD fills up fast, and it's the weakest spec on the sheet
- 180W PSU means no meaningful GPU upgrade path
- 5.89kg is heavy for something marketed as slim

The proof
Performance
The Ryzen 5 8500G is the star here. Six cores, 3.5GHz base, turbo up to 5GHz, and the integrated graphics land in the 97th percentile for this category. That's genuinely impressive for a machine this size. But the RAM situation is rough. 8GB of DDR5 sits in the 17th percentile, which means Chrome with a dozen tabs plus Slack will have this thing wheezing. The 256GB SSD is even worse at the 14th percentile. Windows 11 Pro alone eats a chunk of that, so you're looking at maybe 180GB of usable space after the OS and recovery partition. For a business machine, that's a problem waiting to happen.

vs Competition
The Apple Mac mini M4 Pro absolutely destroys this thing on performance per dollar if you're not locked into Windows. It's smaller, faster, and the base storage is more generous. The Lenovo Legion Tower 5a Gen 10 and HP OMEN GT16-0364 are gaming-focused machines that cost more but come with actual discrete GPUs and upgradeable everything. If you need a business PC that just works and you're already in the Dell ecosystem, this is fine. But the Mac mini makes this look like a relic from 2019.

Price
Value & Pricing
Pricing is all over the place. US listings range from USD 872 to USD 1,186, which is a USD 314 spread for what appears to be the same config. At USD 872 this is a reasonable office machine. At USD 1,186 it's a bad deal, plain and simple. Shop around and don't pay the high end. The CAD listing at CAD 1,189 is a different market, so don't try to compare those numbers directly.

Overview
The Dell Pro QCS1255 is a compact office PC that gets the basics right and not much else. The Ryzen 5 8500G is a genuinely capable chip, and the integrated Radeon 740M graphics punch way above what you'd expect from a slim business box. But 8GB of RAM and a 256GB SSD in 2025 is like buying a car with a full tank and a thimble for a gas tank. It'll get you to work, just don't plan any road trips.
Common Questions
Q: Can I upgrade the RAM and storage later?
Yes, but you shouldn't have to. The RAM is DDR5 and the SSD is M.2 NVMe, so both are technically upgradeable. But you're paying for parts Dell should have included in the first place. Factor in another USD 100-150 for a RAM and storage upgrade if you buy this.
Q: Is this good for gaming?
Not really. The Radeon 740M integrated graphics are surprisingly capable for light gaming and older titles, but the 180W PSU means you can't add a real GPU later. If gaming matters, get a machine with a discrete graphics card.
Q: Does it come with a keyboard and mouse?
Yes, Dell includes a USB keyboard and mouse in the box. They're basic but functional, which is fine for an office machine. You'll probably want to swap them out eventually, but they'll get you started.
Who Should Skip This
If you're a power user, content creator, or anyone who keeps more than a handful of apps open at once, this isn't your machine. 8GB of RAM will have you pulling your hair out. Go get a Mac mini M4 Pro or a proper desktop with 16GB minimum and at least 512GB of storage. The money you save on therapy will cover the price difference.
Verdict
The Dell Pro QCS1255 is a decent office PC hamstrung by two bad decisions: 8GB of RAM and a 256GB SSD. The processor is great, the size is right, and Windows 11 Pro is a nice touch. But you'll be fighting storage warnings and memory pressure within months. If you can find it at the low end of the price range and your workload is email plus spreadsheets, it's acceptable. For anything more, spend a bit extra on more RAM and storage, or look at the Mac mini.
