Choosing a barebone PC: how to build a compact MSI PC without a costly mistake

A barebone PC gives you more freedom than a fully built desktop. You choose components such as RAM and storage, while the processor, case and essential connectivity are already in place. This makes it an interesting option for home workers, IT professionals and business users who want to tailor a PC to their software and working environment.

However, a barebone desktop can also come with surprises. A tempting low price doesn’t always mean you can get started straight away. Before buying, check which components are missing, how much room there is for expansion and whether the size will suit your workspace.

Three common pitfalls when choosing a barebone PC

1. Misunderstanding the term “barebone”

Some models don’t include RAM, storage or an operating system. In effect, you’re buying a basic computer that still needs to be built up. A PC without an operating system also means you’ll need to install Windows or another compatible system yourself.

Be aware of exceptions, too. The MSI CUBI NUC AI 1UMG-018BEU is listed in the product specifications with Windows 11 Home. Always check the current product page before assuming you’ll need to install an operating system yourself.

2. Looking only at the processor

An Intel Core processor alone doesn’t tell you enough about the overall experience. For multitasking, the maximum RAM, memory type and storage interface all matter. A system with limited RAM may struggle sooner when you have lots of browser tabs open, run virtual machines or use business software.

So don’t just look at processor speed. Check support for DDR4 or DDR5 memory, the number of slots and the available M.2 connections.

3. Assuming a compact size means unlimited expandability

A barebone mini PC takes up very little space, but it usually has less room for extra components than a desktop case. Check the internal drive bays, number of M.2 slots and cooling. Don’t place a compact mini PC in an enclosed cabinet either, as its ventilation openings need to remain clear.

Important specifications to check in advance

RAM: capacity and memory type

For office work and home use, 16 GB is often a practical starting point, while intensive multitasking may call for more. Pay particular attention to the maximum capacity and the correct standard:

  • MSI PRO DP180 14A-059BEU: up to 64 GB of internal memory; the product description specifies DDR4 installation.
  • MSI CUBI NUC AI 1UMG-018BEU: up to 64 GB DDR5, with a stated speed of 5,600 MT/s.
  • MSI CUBI NUC 1MG-237BEU: up to 64 GB DDR5 via two SODIMM slots.

A PC with upgradeable RAM is useful if you want to start with less memory and add more later. Check whether you’ll need to buy the modules separately and whether the configuration is compatible with the motherboard.

Storage: M.2, SATA and extra space

An SSD connected via M.2 PCIe is generally faster than a traditional hard drive. Check the number of slots and the supported drive lengths. According to its specifications, the CUBI NUC 1MG-237BEU has two M.2 connections and one SATA-600 connection. This lets you pair a fast system SSD with extra storage, as long as the drives you choose physically fit.

The MSI CUBI NUC AI is listed as supporting two M.2 PCIe 4.0 x4 slots. The MSI PRO DP180 supports M.2 as well as HDD and SSD storage. If you’re looking for a PC with M.2 SSD support, it’s also worth checking the SSD length and how it’s installed.

Connections, networking and placement

For an office setup, multiple monitor outputs, USB ports and a wired network connection may matter more than a slightly higher turbo speed. Check the following:

  • The number of HDMI, DisplayPort and USB connections.
  • Support for Wi-Fi 6 or Wi-Fi 6E.
  • Bluetooth version for your keyboard, mouse and headset.
  • The number and speed of the Ethernet ports.
  • Whether a VESA mount is included.

A VESA mini PC can be mounted behind a monitor. This saves desk space, but check that your monitor arm or VESA plate supports its weight and mounting method.

Which MSI barebone PC is right for you?

The models below are matched to different user profiles based on their stated processor, expansion options, connections and dimensions.

Frequently asked questions about barebone PCs

Is a barebone PC ready to use?

Not always. A barebone PC may not include RAM, an SSD or an operating system. Check the product specifications and what’s included in the box. Some mini PCs come with Windows, while others are intended for you to build up yourself.

How do you install RAM and an M.2 SSD?

Shut down the computer completely, unplug it from the mains and follow the manufacturer’s installation instructions. Only install compatible RAM modules and an M.2 SSD of the correct length. Then install the operating system and the relevant drivers. If you’re not familiar with working with internal components, you can ask a qualified installer to fit them for you.

Does a compact mini PC use less power?

Power consumption depends on the processor, power supply, connected devices and how long you use the PC. A mini PC with a stated power rating of 120W may use less in practice during light office work, but actual consumption varies by configuration. For a reliable comparison, measurements taken during your own working day are more useful than looking at the maximum power supply rating alone.
