Choose the MINISFORUM MS-03 if you need Windows 11 Pro support, extensive internal expansion, or several high-speed wired network connections. Choose the Mac mini M4 if you want macOS in a smaller, lighter desktop and its memory, storage, and ports meet your needs. Neither is a universal performance winner: the right choice depends on your applications, configuration, network equipment, and expansion plans.
At a glance: the main differences
| Decision area | MINISFORUM MS-03 | Mac mini M4 | What it means |
|---|---|---|---|
| Processor | MS-03-S386H: Intel Core Ultra 9 386H, 16 cores and 16 threads. MS-03-S336H: Intel Core Ultra 5 336H, 12 cores and 12 threads. | M4: 10-core CPU and 10-core GPU. | Different architectures and core counts do not establish which system is faster. Compare results for your actual applications and configurations. |
| Memory | Two DDR5 SO-DIMM slots; MINISFORUM lists support for up to 128 GB. | 16 GB unified memory in the base M4 configuration; configurable to 24 GB or 32 GB. | The MS-03 offers replaceable memory and more listed capacity. Apple’s unified memory is a different architecture, so capacity figures are not direct performance equivalents. |
| Storage | Three M.2 NVMe slots: two PCIe 5.0 x4 slots and one PCIe 4.0 x1 slot, subject to the product page’s slot and form-factor details. | 256 GB SSD in the base M4 configuration; configurable up to 2 TB. | The MS-03 provides internal drive expansion. Mac mini buyers should choose internal storage with their needs in mind or plan for external storage. |
| Networking | One 10GbE RJ-45, one 2.5GbE RJ-45, and two 10G SFP+ ports; Wi-Fi 7 and Bluetooth 6 are listed. | Gigabit Ethernet, configurable to 10Gb Ethernet; Wi-Fi 6E and Bluetooth 5.3. | The MS-03 is suited to wired lab or NAS setups when the switches, optics, and cables are compatible. Apple lists a configurable 10Gb Ethernet option. |
| Ports and expansion | Two USB4 ports, HDMI 2.1, several Type-A ports, and a physical PCIe 4.0 x4 expansion slot. MINISFORUM specifies support for a half-height, single-slot card within its listed dimensions. | Three rear Thunderbolt 4 ports, HDMI, Ethernet, and two front USB-C ports. | The MS-03 adds a PCIe card route and multiple built-in network interfaces; the Mac mini offers Thunderbolt and convenient front USB-C. |
| Operating system | Windows 11 Pro support is listed; select SKUs support Intel vPro. | macOS. | Check application, peripheral, and administration requirements before comparing secondary specifications. Do not assume every MS-03 SKU has the same vPro support. |
| Size and weight | 196 × 189 × 48 mm; 1.4 kg. | 12.7 × 12.7 × 5 cm; 0.67 kg for M4. | The Mac mini is smaller and lighter; the MS-03 trades desk space for expansion. |
Specifications are from MINISFORUM’s MS-03 product page and Apple’s Mac mini (2024) technical specifications. They describe the manufacturers’ published configurations, not a matched independent test.
Choose by operating system and applications first
Pick the MS-03 for a Windows-based setup
The MS-03 product page lists Windows 11 Pro support, making it the more natural fit if your required software, peripherals, or management tools depend on Windows. Some MS-03 SKUs list Intel vPro support, but SKU differences matter; verify the exact configuration rather than treating vPro as universal.
Pick the Mac mini if you need macOS
The Mac mini M4 runs macOS. If your work depends on macOS software or Apple workflows, that may settle the choice before you weigh expansion or networking. Confirm that required applications and peripherals support the specific macOS environment you intend to use.

Expansion and memory: the MS-03 offers more internal options
MINISFORUM lists two DDR5 SO-DIMM slots, three NVMe M.2 slots, and a physical PCIe 4.0 x4 slot for the MS-03. Its product page lists memory support up to 128 GB. The three drive slots have different interface specifications—two PCIe 5.0 x4 and one PCIe 4.0 x1—and slot and form-factor details affect what can be installed. Check those details, as well as the supplied configuration, before buying a barebone unit or adding components.
Apple lists 16 GB unified memory and a 256 GB SSD as the base M4 specifications, with M4 memory configurable to 24 GB or 32 GB and storage configurable up to 2 TB. Decide on a sufficient memory and internal-storage configuration at purchase if you want those capacities inside the Mac mini; otherwise, account for external storage where appropriate.
Rank #2

A cluster of four MS-S1 MAX units successfully ran a DeepSeek-R1 671B Q4 large model. A reserved cluster power-on interface allows for unified start-up and shutdown
These capacity figures are not a simple speed comparison. The systems use different memory designs, and the available specifications do not establish how either performs in a particular workload. For virtual machines or plans that depend on substantial replaceable memory or multiple internal NVMe drives, the MS-03’s listed expansion is a practical distinction.
Networking: match the ports to your equipment
The MS-03 has one 10GbE RJ-45 port, one 2.5GbE RJ-45 port, and two 10G SFP+ ports, according to MINISFORUM. That combination can suit a wired lab, NAS, or network-appliance role, but only if the rest of the network supports the relevant link types and speeds. SFP+ use may require compatible optics or direct-attach cables, and actual throughput depends on the connected equipment and network configuration.

MINISFORUM’s store page offers barebone and RAM/SSD bundle configurations and describes two CPU variants. Displayed pricing and available configurations can change, so compare the live listing for the exact SKU you want with the Mac mini configuration you actually need in your region. Include memory, storage, warranty, and return terms when comparing totals; no stable like-for-like price is established by these specifications.
What the published specifications can—and cannot—tell you
The official specification pages establish the listed hardware and configuration options, but they do not establish a directly comparable MS-03 versus Mac mini M4 performance result. CPU core counts across different architectures are not enough to declare a winner, and a vendor-specific benchmark against another model is not a comparison with the Mac mini M4. Apple’s October 29, 2024 launch announcement included a company performance claim against a PC desktop in the Mac mini’s price range; it does not establish how the M4 compares with the MS-03. See Apple’s launch announcement for the claim and its stated comparison.
Quick Recap
Which compact PC should you buy?
- Choose the MINISFORUM MS-03 if Windows 11 Pro support, replaceable SO-DIMM memory, multiple internal NVMe slots, PCIe card expansion, or its combination of high-speed wired network ports fits your work.
- Choose the Mac mini M4 if macOS is required or preferred and a smaller, lighter desktop matters more than the MS-03’s internal expansion and wired-network selection. Configure memory and storage for your needs.
- Compare the exact workload and SKU if performance is the deciding factor. These published specifications do not provide a direct independent benchmark between the two systems.
