BMAX MaxMini B4 Ultra

It suits someone who wants a small Windows 11 Pro machine for email, documents, web apps and video, set up once and left alone. It arrives complete, with 12 GB of memory and a 512 GB NVMe drive installed, so there is nothing to assemble. Four USB-A ports and two HDMI outputs cover a keyboard, mouse, printer and a pair of screens.

Skip it if you compile code, run containers, play games or want to run language models locally. The 12 GB is soldered and is also the maximum, so a workload that outgrows it has nowhere to go. A single 1GbE port also rules it out as a network appliance.

Everyday use is well suited. An Intel N150 with 4 cores and 4 threads, 12 GB of LPDDR5 and a 512 GB NVMe drive are enough for browsing, office documents, video calls and streaming on Windows 11 Pro.

Coding is a poor fit. The 12 GB is soldered with no upgrade path, and an editor, a browser full of documentation and a local build will press against that ceiling with no way to raise it.

Gaming is a poor fit. Graphics come from integrated Intel Graphics, and BMAX does not state how much memory the graphics can use.

Homelab use is a poor fit. There is one network port at 1GbE, so the box cannot act as a router with separate WAN and LAN ports, and the fixed 12 GB limits how many virtual machines or containers fit at once.

Local AI is a poor fit. With 12 GB of soldered memory and only integrated graphics, little room is left for a language model once Windows takes its share, and BMAX does not state the memory bandwidth.

One build is described here: the Intel N150 with 12 GB of LPDDR5, a 512 GB NVMe drive and Windows 11 Pro, sold new as a complete machine rather than a barebones kit, released in 2025. With no choice on processor or memory, the decision is about your workload: if 12 GB covers what you do now and later, this is the build; if not, it is the wrong machine rather than the wrong configuration. Storage, by contrast, can grow, since there are two M.2 slots for the single installed 512 GB drive.

Memory is fixed. There are no memory slots, the 12 GB of LPDDR5 is soldered to the board, and 12 GB is also the maximum, so what you buy is what you keep.

Storage has some headroom. There are two M.2 slots of the 2280 length, so you can add an M.2 drive beside the installed 512 GB NVMe drive. The first slot runs at PCIe Gen 3, BMAX does not state the generation of the second slot, and the slots also accept M.2 SATA drives. There are no SATA bays.

You can run two screens, both from the two HDMI outputs; there is no DisplayPort output. BMAX does not state the HDMI version, so check it before relying on a high-resolution, high-refresh monitor.

For peripherals there are four USB-A ports and one USB-C port. Wired networking is a single 1GbE port. The wireless standard is Wi-Fi 5 with Bluetooth 5.0, though BMAX does not confirm that the wireless module is included. There is no OCuLink port.

The 12 GB of soldered memory is the hard limit, and nothing raises it. Networking stops at one 1GbE port, and there is no DisplayPort output or OCuLink port. BMAX does not state the volume, the graphics memory, the memory speed or bandwidth, ECC support, the second M.2 slot's PCIe generation, whether a wireless module is included, USB4 or Thunderbolt ports, the HDMI version, an SD card reader, the power supply, the TDP or a VESA mount.

When you weigh other ultra-compact machines, compare the memory first: whether it sits in removable slots and how high the maximum goes, since this one is fixed at 12 GB. Then set their network ports and speed against this single 1GbE port, and their display count against this machine's two. The storage layout is worth matching too: two M.2 slots here, the first at PCIe Gen 3.
