Bmax B4 Plus

Updated on June 23, 2026

The BMAX B4 Plus pairs the Intel N100 with a dedicated 2.5-inch SATA bay, so a second drive goes in alongside the M.2 NVMe SSD instead of replacing it. It ships with 16GB of DDR4 and a 512GB NVMe SSD, which covers everyday desktop work out of the box and leaves the bay free for a media library, a backup target, or a home server’s data volume. Windows 11 Professional is preinstalled, and a VESA bracket in the box lets the machine hang behind a monitor.

A SATA bay next to the M.2 slot

The Intel N100 runs four efficient cores at up to 3.4GHz, which covers office work, web browsing, and video playback without the heat or power draw of a faster chip. The 16GB of DDR4 sits in one slot running single channel, so multitasking is comfortable but 16GB is the ceiling, because there is no second slot to fill later. Document editing, email, and streaming stay responsive, and the platform is quiet enough about power that it can run all day without attention.

The 2.5-inch bay takes a standard laptop hard drive or SSD of several terabytes, so the included NVMe drive can hold the operating system while bulk data lives on cheaper storage. The M.2 2280 slot holding the 512GB SSD can also be swapped for a larger NVMe drive, which gives two separate upgrade paths. Home servers, local backup targets, and media libraries are the workloads that need that combination, and they are the reason to pick this box over a smaller N100 machine that has room for one drive.

Two HDMI ports carry 4K 60Hz output for a dual-monitor desk, and the USB-C port adds DisplayPort alternate mode for a third screen. The front panel holds two USB 3.0 ports and the Type-C port, while two USB 2.0 ports on the rear cover a keyboard, a mouse, and other legacy devices. Wired networking stops at gigabit Ethernet, so file moves across a 2.5GbE switch will be capped at the machine. WiFi 5 and Bluetooth 4.2 are the oldest parts of the spec sheet, and a combo audio jack handles headphones and a headset mic.

Cooling is active, with a fan and visible chassis vents, and noise stays modest under normal desktop load. The plastic shell keeps weight under a pound and keeps the price down, though it feels less solid in the hand than a metal-bodied box. At roughly 4.4 x 4.92 x 1.85 inches the machine is larger than the smallest N100 systems and far smaller than a desktop tower, and that extra thickness is where the drive bay lives.

Reviewer Insights

Living Linux: accessible screws and a drive bay

Living Linux unboxes the machine and takes it apart on camera. The reviewer picks the 2.5-inch SATA bay as the differentiator, noting “This one also has a slot for a 2.5 inch drive.” Disassembly is straightforward, and the reviewer observes that “The screws are accessible, probably to make it easier to install the 2.5 inch drive.”

He recommended it with a condition: “If you really want to have a lot of storage but you still want a small computer, then this is an interesting option.” The video walks the internal layout, showing the single RAM slot with its 16GB module, the M.2 2280 SSD position, and the dedicated SATA connector and bay.

Customer Reviews

Across 60 ratings on Amazon, the Bmax B4 Plus averages 4.1 stars, with most owners (65 percent) leaving five stars and 13 percent leaving one star. Buyers using it for ordinary desktop work and media tend to be the happiest. A verified buyer, “Almost Satisfied,” replaced an aging tower with it and reported it “works perfectly” for email and web browsing, though they added a minor gripe: “My only complaint is that the audio jack is on the front.” Another verified owner, LR, gave it four stars and a narrower use case: “I use this for my PLEX server,” along with Netflix, YouTube, and casual browsing.

The most pointed one-star review, from verified buyer michael lumley, is about the listing not matching the hardware: he expected Linux and got Windows instead, writing “Description says Pro Ubuntu. I specifically needed a Linux device that is not a VM.” A three-star review from Jason C. Coleman, who owns several N100 mini PCs, said it “runs as expected” once set up but that he hit trouble with his first unit out of the box. If you specifically need a Linux machine, confirm the OS before buying; for basic Windows desktop and media use, the reviews skew positive.

Buy it for the storage bay, skip it if you need WiFi 6

If a second drive matters to you, this is a cheaper route than hanging external storage off a smaller machine, and the included NVMe drive stays free to run the operating system. If one 512GB drive covers everything you do, a more compact N100 box does the same desktop work in less space for the same kind of money.

Memory stops at 16GB with no second slot, so there is no headroom to buy later, and the wireless stack sits on WiFi 5 and Bluetooth 4.2. Neither matters for a machine wired to a router and used for documents, browsing, and streaming. They matter more if this is meant to be a main computer for the next several years.
