2026 verdict
MINISFORUM's MS line moves through generations quickly, and the MINISFORUM MS-03 (Ultra 9 64GB + 1TB) wins because it ships the memory its owner was going to add anyway.
It arrives with 64 GB of DDR5 at 5600 MT/s, replaces the 285HX's 13 TOPS NPU with a 50 TOPS one, and offers four wired network interfaces including two 10G SFP+ cages, all in a 1.4 kg chassis with vPro remote management. The MINISFORUM MS-02 Ultra (Ultra 9 285HX, 32GB + 1TB) counters with a higher core count, four memory slots that reach 256 GB, four M.2 positions, a PCIe 5.0 x16 slot and an internal 350 W supply. Pick the MS-03 for a compact networking and inference box and the MS-02 for the most expandable workstation.

What the differences mean
Memory
The MINISFORUM MS-03 (Ultra 9 64GB + 1TB) ships 64 GB of DDR5 at 5600 MT/s and tops out at 128 GB. The MINISFORUM MS-02 Ultra (Ultra 9 285HX, 32GB + 1TB) starts at 32 GB at 4800 MT/s but reaches 256 GB across four SO-DIMM slots. One gives capacity now, the other headroom later.
Processor and NPU
The MS-02 Ultra runs a 24-core Core Ultra 9 285HX with a 13 TOPS NPU. The MS-03 runs a 16-core Core Ultra 9 386H whose NPU is rated 50 TOPS with a further 40 TOPS from its integrated graphics, which makes local model inference the newer machine's strong suit despite the lower core count.
Networking
The MS-03 has two 10G SFP+ cages plus a 10GbE and a 2.5GbE RJ45 port with vPro. The MS-02 Ultra goes further on optical speed with two 25GbE SFP+ ports plus 10GbE and 2.5GbE. Both offer four wired interfaces; the MS-02's are faster and the MS-03's support remote management.
Expansion
The MS-02 Ultra has four M.2 positions and three PCIe slots including a PCIe 5.0 x16, so a low-profile card is an option. The MS-03 has three M.2 bays, two at PCIe 5.0 x4 with U.2 support, and a single half-height PCIe 4.0 x4 slot wired for smaller cards.
Power and size
The MS-02 Ultra builds a 350 W supply into a 4.8-litre chassis and weighs 3.45 kg. The MS-03 is 1.4 kg and 48 mm tall but uses an external 240 W brick, so part of its size advantage ends up on the desk.
Which one to buy if
- you want maximum memory for virtualization
The MINISFORUM MS-02 Ultra (Ultra 9 285HX, 32GB + 1TB) takes four SO-DIMMs up to 256 GB, double the ceiling of the MS-03.
- you want 64 GB and a 50 TOPS NPU out of the box
The MINISFORUM MS-03 (Ultra 9 64GB + 1TB) ships with 64 GB of faster memory and a much stronger NPU for local AI work.
- you want remote management at a branch or rack
The MS-03 has vPro on its 2.5GbE port, so it can be managed and recovered remotely.
- you want the fastest optical networking
The MINISFORUM MS-02 Ultra carries two 25GbE SFP+ ports against the 10G SFP+ cages on the MS-03.
- you plan to add a low-profile graphics card
The MS-02 Ultra offers three PCIe slots including a PCIe 5.0 x16, far more room than the MS-03's half-height PCIe 4.0 x4 slot.

What owners say
MINISFORUM MS-02 Ultra (Ultra 9 285HX, 32GB + 1TB) owners describe a powerful, well-built machine that opens with two screws and exposes its upgrade points immediately. Several run it as a Proxmox or Hyper-V host for Plex, Windows 11, Home Assistant and network services, and report it handles many virtual machines once the memory is maxed out. The port selection and fast networking come up repeatedly, along with quiet everyday running, where the power-supply fan is the one component they notice. The recurring caveats concern software maturity: some installed drivers by hand for Windows Server, and Linux and Proxmox drew complaints about PCIe behaviour and an IOMMU quirk with this CPU, with one owner finding the 25GbE NVMe card caused performance issues when fitted. One buyer received the 32 GB configuration as a single module, so adding a second meant opening the front memory slots.

Frequently Asked Questions
Which is better overall: MINISFORUM MS-02 Ultra (Ultra 9 285HX, 32GB + 1TB) or MINISFORUM MS-03 (Ultra 9 64GB + 1TB)?
They aim at different jobs. The MINISFORUM MS-03 (Ultra 9 64GB + 1TB) is the better networking and inference box, with 64 GB of faster memory, a 50 TOPS NPU, four wired interfaces and vPro. The MINISFORUM MS-02 Ultra (Ultra 9 285HX, 32GB + 1TB) is the better expandable workstation, with 256 GB of memory available and a PCIe 5.0 x16 slot for a low-profile card.
What is the biggest difference between the MINISFORUM MS-02 Ultra and the MINISFORUM MS-03?
Memory and expansion. The MINISFORUM MS-02 Ultra ships 32 GB and reaches 256 GB across four SO-DIMM slots with three PCIe slots, while the MINISFORUM MS-03 ships 64 GB at 5600 MT/s, tops out at 128 GB and has one half-height PCIe 4.0 x4 slot. The MS-03 also has the stronger NPU.
Do the MINISFORUM MS-02 Ultra and the MINISFORUM MS-03 have built-in power supplies?
Only the MINISFORUM MS-02 Ultra does, a 350 W unit inside its chassis. The MINISFORUM MS-03 (Ultra 9 64GB + 1TB) uses an external 240 W power brick, which helps it stay 48 mm tall but adds a block to the desk or rack.
Which MINISFORUM machine is better for local AI, the MS-02 Ultra or the MS-03?
The MINISFORUM MS-03 (Ultra 9 64GB + 1TB), whose Core Ultra 9 386H carries a 50 TOPS NPU plus 40 TOPS of integrated graphics. The MINISFORUM MS-02 Ultra (Ultra 9 285HX, 32GB + 1TB) has more cores but a 13 TOPS NPU.
Who should buy the MINISFORUM MS-02 Ultra (Ultra 9 285HX, 32GB + 1TB)?
Anyone who wants the most upgradeable small workstation: 24 cores, four memory slots up to 256 GB, four drive positions, three PCIe slots including a PCIe 5.0 x16 and dual 25GbE, with an internal power supply.
Who should buy the MINISFORUM MS-03 (Ultra 9 64GB + 1TB)?
Buyers who need a very small box with four wired network interfaces including two 10G SFP+ cages, vPro management, 64 GB of memory out of the box and a strong NPU for inference, and who do not need a full graphics card.
