The ASUS NUC 15 Pro Slim is a sleek, barebones mini PC kit. You get a modern chassis and CPU, but you must add your own RAM and storage. Is the compact size worth the extra work and cost?

The 30-Second Version

The ASUS NUC 15 Pro Slim is a sleek, ultra-compact barebones PC. It's fantastic for basic work and has future-proof Wi-Fi 7 and Thunderbolt 4 ports. But you must add your own RAM and storage, and it's not for gaming. Worth it only if you really need that tiny form factor.

Overview

The ASUS NUC 15 Pro Slim is a barebones kit, which means you're buying the shell, the motherboard, and the processor. You'll need to add your own RAM and storage before it'll even boot. That's the whole point: you get a tiny, modern PC chassis and can pick your own memory and SSD. It's powered by Intel's Core Ultra 5 225H, a 14-core chip with integrated Arc graphics, and it's absolutely loaded with modern ports like Thunderbolt 4 and Wi-Fi 7. This isn't a plug-and-play desktop; it's a project for someone who wants a specific, compact form factor.

Performance

The Intel Core Ultra 5 225H lands in the 57th percentile for CPU performance in our database, which is solid for general productivity. It'll handle office work, web browsing, and light creative tasks without breaking a sweat. The integrated Intel Arc graphics are a step up from older Intel graphics, but they're still integrated graphics. Our score puts it in the 43rd percentile for GPU power, which means it's fine for a second monitor and maybe some very old games, but that's it. Don't expect to game on this thing.

The Word on the Street

5.0/5 (1 reviews)
👍 Owners who complete the build praise how easy it is to set up and how seamlessly everything works once assembled.

Value & Pricing

At around $517 for the barebones kit, the value proposition is a bit tricky. You're paying a premium for the ultra-compact form factor and the latest connectivity. Once you add 16GB of DDR5 RAM and a 1TB NVMe SSD, you're looking at a total system cost of roughly $700-$750. For that price, you could buy a pre-built mini PC with similar specs. So the value is only there if you specifically want this exact chassis or need to reuse components you already own.

₹94,801

vs Competition

This sits in a weird spot. It's not a gaming PC like the HP Omen or Corsair Vengeance towers, which have dedicated GPUs. Compared to other mini PCs, it's more modern than most with its Wi-Fi 7 and PCIe 5.0 slot, but you have to build it yourself. A pre-built mini PC from Beelink or Minisforum at a similar total price might give you a more powerful AMD Ryzen APU with better integrated graphics for light gaming. The NUC 15 Pro Slim's main advantage is its ASUS build quality and that killer port selection.

Common Questions

Q: What exactly do I need to buy to make this work?

You'll need to purchase at least one stick of DDR5 SO-DIMM laptop RAM and at least one M.2 NVMe SSD. A 16GB RAM kit and a 1TB SSD are good starting points.

Q: Can this PC run games?

Not really. It uses integrated Intel Arc graphics, which are fine for video playback and very old games, but it scores in the bottom half for GPU performance in our tests. Look elsewhere for gaming.

Q: Is the Windows 11 license included?

Yes, the kit is 'Windows 11 OS Ready,' which means the license is tied to the motherboard. Once you install your own RAM and storage, you can install Windows and it should activate automatically.

Who Should Skip This

Skip this if you want a PC that works right out of the box. Also, hard pass if you need any kind of gaming or GPU-accelerated performance. If your budget is tight, you can likely find a pre-built mini PC with similar specs for less total money than this kit plus components.

Verdict

Buy this if you're a tech-savvy user who needs an ultra-compact, clean-looking desktop for basic tasks and values having the latest ports like Thunderbolt 4. It's perfect for a home office setup, a digital signage box, or a living room media PC where you want zero cable clutter. Just be ready to install your own RAM and storage.
