Choosing an MSI barebone PC: a practical guide to RAM, storage and expandability

An MSI barebone PC gives you more control over how your computer is configured. You choose the memory, storage and, in some cases, the operating system. This makes it an appealing option for people working from home, small businesses, IT professionals and DIY enthusiasts who don’t want to buy a standard configuration.

However, it’s easy to make the wrong choice when buying a barebone desktop PC. Buyers sometimes focus mainly on the processor name or compact size, even though compatibility, connections and what’s included in the box are just as important.

Common pitfalls when choosing an MSI barebone PC

1. A barebone isn’t always ready to use straight away

The term barebone usually means that some components are missing. These might include RAM, an SSD or an operating system. Before you buy, check:

  • Is RAM included?
  • Is an M.2 or SATA SSD already installed?
  • Is Windows included, or are you buying a PC without an operating system?
  • Is the required power adapter included?
  • Are mounting components and cables included?

Pay particular attention if the title and specifications seem to contradict each other. The MSI CUBI NUC AI 1UMG-018BEU is described as a barebone product, but its specifications also mention Windows 11 Home. Check the current product page and what’s in the box before assuming you’ll need to install your own operating system.

2. A compact case doesn’t automatically make upgrades easy

Space is limited in a compact mini PC. Some models have two M.2 slots, while others also support a 2.5-inch SATA drive. Check the memory type, too. DDR4 and DDR5 are not interchangeable.

An MSI CUBI NUC generally uses compact SODIMM modules. These are laptop-style memory modules, not standard desktop DIMMs. The MSI PRO DP180 has a desktop case and lists support for up to 64 GB of internal memory, but its specifications refer to DDR4. The right module therefore depends on the specific model.

3. Connections are often judged too broadly

“Lots of ports” doesn’t tell you much without the number and version of each one. Check for the connections you actually use:

  • HDMI 2.1 or DisplayPort for monitors;
  • USB-A for peripherals;
  • USB-C or Thunderbolt 4 for fast storage and docks;
  • one or two RJ45 ports for a wired network;
  • a card reader, audio input and microphone connection;
  • Wi-Fi 6 or Wi-Fi 6E for wireless connections.

A Wi-Fi 6E mini PC can use the 6GHz band, but you’ll also need a compatible router and network setup. Without this equipment, the device won’t automatically work faster.

Important specifications to compare

Processor and graphics capabilities

For office work, browsing, administration and video calls, an Intel Core i5 or Intel Core 7 is generally a sensible starting point. The MSI PRO DP180 uses an Intel Core i5-14400 with 10 cores and 16 threads. Its integrated Intel UHD Graphics 730 is designed for displaying images and everyday applications; no separate graphics card is listed.

The MSI CUBI NUC models use mobile Intel processors. The CUBI NUC AI 1UMG-018BEU uses an Intel Core Ultra 7 155H with 16 cores, integrated Intel Arc graphics and an NPU. The CUBI NUC 1MG-237BEU uses an Intel Core 7 150U. These models are worth considering if a small form factor matters more to you than the option to add a separate desktop graphics card later.

RAM: capacity and memory type

Less memory may be enough for basic office work, but more is useful for lots of browser tabs, virtual machines, photo editing or business software. Keep three things in mind:

  1. Maximum capacity: the MSI models listed support up to 64 GB.
  2. Memory type: the CUBI NUC models use DDR5; the PRO DP180 lists DDR4.
  3. Number of slots: two SODIMM slots let you combine modules, as long as their capacity and speed are compatible.

Choose memory based on the official specifications for the exact model, not just the processor range.

Storage and expandability

The term M.2 SSD support doesn’t tell you which size or protocol is used. The CUBI NUC 1MG-237BEU lists two M.2 PCIe 4.0 x4 connections, as well as SATA support. This gives you more flexibility to add a fast system SSD and extra storage.

The MSI CUBI NUC AI also lists two M.2 PCIe 4.0 x4 slots. The MSI PRO DP180 supports M.2 and SATA storage and has one 3.5-inch bay. This larger model is therefore better suited to adding an extra internal drive.

Always check the maximum M.2 size, whether a mounting screw is available and whether an SSD is actually included.

Installation and everyday use

Place the PC on a stable, dry surface and keep the ventilation openings clear. If you’re installing RAM or an SSD, shut the system down completely and unplug the power cable. For compact models, use the supplied adapter and check that all connections are secure.

Once everything is installed, check the BIOS. You can use it to see whether the memory and storage are recognised. Then install your preferred operating system and the latest drivers from the manufacturer. For business applications, it’s a good idea to check in advance that your software is compatible with the processor and integrated graphics solution you’ve chosen.

Frequently asked questions about MSI barebone PCs

Does an MSI barebone PC come with Windows?

It depends on the model and version. Barebone PCs are often supplied without RAM, storage or an operating system. Windows 11 Home is listed in the specifications for the MSI CUBI NUC AI 1UMG-018BEU, even though the product title describes it as a barebone. Always check the current contents of the box.

Can I install RAM and an SSD myself?

The models mentioned can be upgraded, but the type of component varies. The CUBI NUC systems use DDR5 SODIMM memory and M.2 storage. The PRO DP180 lists DDR4 and support for M.2 and SATA. Check the capacity, size and interface before ordering components.

Does a compact mini PC use less power?

A small case alone doesn’t tell you how much power the system uses. Power consumption depends on the processor, power supply, storage and workload. The CUBI NUC models use an external 120 W power supply; the PRO DP180 lists a 350 W power supply. Depending on how you use it, actual consumption is generally lower than the maximum power rating.
