This article covers Intel (インテル) NUC 8 メインストリームキット (NUC8i3BEH).

Overview

The Intel NUC 8 Mainstream Kit NUC8i3BEH is a compact desktop PC powered by an 8th-generation Core i3-8109U processor. Designed for users who need a full Windows experience in a tiny footprint, this kit comes with Windows 10 pre-installed and requires only a display, keyboard, and mouse to get started. Measuring just 117×112×51mm (tall version), the NUC can sit unobtrusively on a desk or be mounted behind a monitor using the included VESA bracket. The hardware is well-suited for everyday office tasks, media consumption, and light creative work, with the Intel Iris Plus Graphics 655 providing capable 4K video playback.

Connectivity & Compatibility

The front panel offers two USB 3.0 ports, a headphone jack, HDMI 2.0a, and a Thunderbolt 3 (USB-C) port. The rear adds two more USB 3.0 ports, another HDMI 2.0a, gigabit Ethernet, and the DC power input. Dual HDMI plus Thunderbolt 3 allow up to three independent 4K displays. For storage, there is one M.2 slot (22×42/80, supporting both NVMe and SATA SSDs) and one 2.5-inch SATA bay. Two DDR4-2400 SO-DIMM slots accept up to 32 GB of RAM. Wireless connectivity is handled by an integrated Intel Wireless-AC 9560 module (Wi-Fi 5 + Bluetooth 5.0).

Product Info

Released in 2018, the NUC8i3BEH is positioned as an entry- to mid-range compact desktop. Pricing as of August 2026 is around ¥85,000 on Japan. The standard warranty is three years from Intel. Included accessories: power adapter, VESA mount bracket, power cord, and quick-start guide. Its market position is a solid value pick for users who need a space-saving Windows PC without breaking the bank. The Core i3-8109U with Iris Plus Graphics delivers enough performance for office productivity, web browsing, and 4K media playback, but it is not intended for gaming or heavy 3D work.

Best Use Cases

Remote workers and office users: The NUC takes up minimal desk space and runs silently. It easily handles Microsoft Office, web conferencing, and multi-tab browsing. It is not suitable for CAD or video editing, but for typical office tasks it performs admirably. Home theater PC (HTPC): With dual HDMI and Thunderbolt 3, it can drive multiple 4K displays and play streaming services smoothly. Its compact size fits neatly into AV racks or behind televisions. Note that it lacks hardware decoding for AV1 codecs, so some latest-format streams may require software decoding. Digital signage or light server: VESA mount compatibility and low power consumption (typically 20–30W) make it ideal for always-on applications like menu boards or home file servers. The maximum RAM of 32 GB may be limiting for heavy virtualization, but basic roles are well within its capabilities. First-time PC buyers seeking simplicity: The pre-installed Windows 10 eliminates setup hurdles. Upgrading RAM or swapping the SSD is straightforward with a screwdriver. If you do not need gaming performance and value a clean, compact workstation, this NUC is a strong contender.
