MINISFORUM MS-02 Ultra Review: A 24-Core Workstation in a 4.8-Litre Box
The MINISFORUM MS-02 Ultra packs a 24-core Intel Core Ultra 9 285HX, four DDR5 SO-DIMM slots, four M.2 drive positions and dual 25GbE networking into a 4.8-litre chassis with a built-in 350W power supply. It is built for home-lab virtualisation, local AI experiments and media work where memory and network bandwidth matter more than gaming. Owners praise its tool-light build, upgradability and quiet everyday running, while some report driver, PCIe and IOMMU quirks under Linux and Proxmox, and the integrated graphics stay modest unless a low-profile desktop card is added. For a compact always-on workstation or server, it is a strong, if premium, choice.

Who is the MINISFORUM MS-02 Ultra for?
This is a mini workstation for people who want server-class hardware in a small, quiet, always-on box. A 24-core Core Ultra 9 285HX with an NPU rated at up to 13 TOPS suits virtualisation (Proxmox, Hyper-V), a media server, Home Assistant and other self-hosted services, light local AI inference, and creative work that benefits from fast networking. The four memory slots and four drive positions mean it grows with the workload, and the built-in power supply keeps an external brick off the desk. It is not a gaming box out of the box: it relies on Intel integrated graphics until a discrete card is added.
What the MS-02 Ultra offers
The heart is a 24-core Intel Core Ultra 9 285HX (8 performance and 16 efficiency cores) boosting to 5.5 GHz, paired with an Intel NPU rated up to 13 TOPS and integrated Intel graphics running up to 2 GHz. Memory is four DDR5 SO-DIMM slots supporting up to 256 GB at 4800 MT/s, with ECC supported on this 285HX model, and storage is four M.2 2280 positions: two on the motherboard at PCIe 4.0 x4 and two on the bundled 25GbE NIC card, with RAID 0/1/5/10. Networking is unusually deep, with two 25GbE SFP+ ports on the 285HX, one 10GbE RJ45 and one 2.5GbE RJ45, plus Wi-Fi 7 and Bluetooth 5.4. Video runs through one HDMI 2.1 FRL port and DisplayPort Alt Mode over USB4, and the machine carries two Thunderbolt 5 (USB4 V2, 80Gbps) ports, a third USB4 port at 40Gbps and four USB-A 10Gbps ports. A 350W power supply is built in, it ships with Windows 11 Pro, and cooling uses a six-heatpipe radiator, dual fans and phase-change material.
What owners say
Buyers describe the MS-02 Ultra as a powerful, well-built machine that opens with two screws and exposes its upgrade points immediately. Several run Proxmox or Hyper-V as a hypervisor for Plex, Windows 11, Home Assistant and network services, and report it handles many virtual machines with the memory maxed out. The port selection and fast networking come up repeatedly as highlights, along with quiet everyday running, where the power-supply fan is the one component owners notice. The recurring caveats concern software maturity: some had to install drivers by hand for Windows Server, and Linux and Proxmox support drew complaints about PCIe behaviour and an IOMMU quirk with this CPU, with one owner finding the 25GbE NVMe card caused performance issues when installed. One buyer received the 32GB configuration as a single module, so adding a second meant opening the front memory slots.
What to know before you buy
The integrated Intel graphics are modest, which is fine for a server or office workload but not for gaming; the machine supports a low-profile dual-slot PCIe 5.0 x16 card if you need real graphics. One owner warns the built-in 350W supply can be tight for a demanding card such as an RTX 5060, and that low-profile cards can be hard to source. There is no SD card slot, fingerprint reader, VESA mount, built-in speaker or microphone. Linux users should budget time for driver and PCIe tuning, while Windows and Windows Server are the path of least resistance. Note also that this is the 285HX configuration with 32GB and a 1TB drive out of the box, unlike the barebone versions some reviewers discuss.
Is the MINISFORUM MS-02 Ultra worth it?
The case rests on density and upgradability. You get a 24-core workstation, four memory slots, four drive positions, three PCIe slots including a PCIe 5.0 x16, dual 25GbE networking and a 350W internal supply in 4.8 litres, with the memory and storage user-replaceable. Comparable tower workstations cost less to expand but take far more space and power, and compact rivals rarely match the networking or slot count. If the workload is virtualisation, local services or AI experiments and you want it small, quiet and upgradeable, the MS-02 Ultra is a well-rounded flagship. If you need strong graphics out of the box, plan for a discrete card.
Frequently asked questions
What processor and graphics does the MS-02 Ultra use?
It is built around a 24-core Intel Core Ultra 9 285HX (8 performance and 16 efficiency cores) that boosts to 5.5 GHz, with an Intel NPU rated up to 13 TOPS and integrated Intel graphics running up to 2 GHz. A discrete low-profile GPU can be added through the PCIe 5.0 x16 slot.
How much memory and storage can it hold?
Four DDR5 SO-DIMM slots take up to 256 GB at 4800 MT/s, with ECC supported on the 285HX model, and four M.2 2280 positions accept NVMe drives, two at PCIe 4.0 x4 on the board and two on the 25GbE NIC card, with RAID 0/1/5/10 support.
Does it have Thunderbolt and USB4?
Yes. The 285HX model has two Thunderbolt 5 ports over USB4 V2 at 80Gbps and an additional USB4 port at 40Gbps, alongside four USB-A 10Gbps ports. Video output also runs over one HDMI 2.1 port and DisplayPort Alt Mode on the USB4 ports.
What networking does it have?
On the 285HX model there are two 25GbE SFP+ ports, one 10GbE RJ45 port and one 2.5GbE RJ45 port, plus Wi-Fi 7 and Bluetooth 5.4.
Is it good for a home server or Proxmox?
The hardware is well suited to virtualisation and always-on services, with plenty of cores, memory and network bandwidth. Some owners report that Linux and Proxmox need driver and PCIe or IOMMU tuning, so expect some setup work outside Windows.
Does it come with Windows?
This configuration ships with Windows 11 Pro pre-installed. MINISFORUM also sells barebone versions without memory, storage or an operating system.
