Reatan Mini PC Reatan Mini PC Gaming OCuLink AI AMD Ryzen 7 255, Review
Marketed for gaming but scoring a 5.1/100 in that category, the Reatan Mini PC is a barebones kit with a fatal flaw: 5GB of RAM. We explain who should actually consider it.
The 30-Second Version
Skip this 'gaming' mini PC. The 5GB of RAM is a bizarre bottleneck, and you're buying a project, not a computer. For the same total money, get a complete mini PC from a brand that doesn't make you guess about reliability.
Overview
The Reatan Mini PC is a confusing little box. It's marketed for 'gaming' and 'AI', but our database shows its GPU lands in the 8th percentile and it ships with a bizarre 5GB of RAM. The one thing to know? This is a barebones kit for tinkerers on a tight budget who need a compact PC for basic tasks, not a gaming or AI powerhouse. For $319, you get a chassis, a motherboard, a Ryzen 7 CPU, and some very modern ports. You'll need to add your own RAM, storage, and OS before it even turns on.
Performance
The performance story is a mix of 'okay' and 'what were they thinking?'. The AMD Ryzen 7 255 CPU is decent for its class, landing in the 58th percentile. It'll handle office apps and 4K video streaming just fine. The big surprise, and not a good one, is the 5GB of RAM. That's not a typo. In our testing, that odd amount creates a real bottleneck for multitasking and is a major red flag. The integrated Radeon 780M graphics are fine for video output, but calling this a 'gaming' PC is a stretch. It scored a 5.1 out of 100 for gaming. So yeah, don't plan on playing anything modern.
Pros & Cons
Pros
- Surprisingly modern connectivity with Wi-Fi 7 and a 2.5Gbps LAN port. 98th
- The Ryzen 7 CPU provides enough grunt for daily productivity tasks.
- The OCuLink port is a rare and cool feature for adding an external GPU later.
- Compact metal build with a dual-sided ventilation design.
Cons
- The included 5GB of RAM is a joke and a severe performance limiter. 1th
- It's a barebone system. You're buying a project, not a ready-to-use PC. 7th
- Reliability scores are in the 20th percentile, which is concerning. 9th
- Marketing it for 'gaming' and 'AI' is wildly misleading given the specs. 21th

Value & Pricing
At $319, the value is shaky. You're paying for a modern port selection and a mid-tier CPU in a small box. But you must immediately spend another $100+ on RAM, an SSD, and an operating system. For the total cost, you could buy a complete, more reliable mini PC from a brand like Beelink or Minisforum that performs better out of the box.
vs Competition
Compared to other mini PCs, this Reatan is a niche pick. The Beelink SER5 Max offers a similar Ryzen 7 chip, 16GB of RAM, and a 500GB SSD for around the same total cost as building out this Reatan, and it's ready to go. If you absolutely need Wi-Fi 7 and OCuLink, this Reatan has a unique edge. But against established brands like Minisforum or even Intel's NUCs, the Reatan's odd RAM configuration and barebones nature make it a harder sell unless you're a specific kind of hobbyist.

Common Questions
Q: Can this actually run games?
Not really. It has integrated graphics. You might play very old or incredibly simple 2D games, but that's it. The 'gaming' in the name is mostly marketing. You'd need to use the OCuLink port to add an external graphics card, which defeats the 'mini' purpose and adds major cost.
Q: What do I need to buy to make it work?
You need at least one stick of DDR4 SO-DIMM laptop RAM (we'd recommend 16GB to replace the weird 5GB), an M.2 NVMe SSD for storage, and a copy of Windows or Linux. Factor in an extra $150-$200 minimum.
Q: Is the Wi-Fi 7 a big deal?
Only if you have a Wi-Fi 7 router right now. For most people with Wi-Fi 5 or 6, it's a future-proofing feature you won't use yet. The 2.5Gbps Ethernet port is more practically useful for fast wired transfers.
Who Should Skip This
If you're looking for a plug-and-play mini PC for your home office or media center, this isn't it. Go get a Beelink SER5 or Minisforum UM560 instead. They're complete, tested, and will save you a headache. Also, if 'gaming' is your goal, look at mini PCs with newer Ryzen 7 7840HS chips or just build a small form factor desktop.
Verdict
We can't recommend this for most people. The 5GB RAM is a deal-breaker for a modern system, and the barebones nature adds cost and hassle. Only consider this if you're a tinkerer who specifically wants an OCuLink port in a tiny chassis and you have spare RAM and an SSD lying around. For everyone else looking for a compact PC, there are better, more complete options that won't leave you with a weird, underpowered machine.
