Compact desktop for office and media

The Corn Electronics J3455 Mini PC is a small-form-factor desktop built around a quad-core Intel Celeron J3455 processor that runs at 1.5 GHz and can reach 2.3 GHz in burst mode. It ships with Windows 10 Pro 64-bit pre-installed and includes 6GB of DDR3 memory plus a 120GB mSATA SSD. The system targets users who need a quiet, space-saving machine for everyday productivity, web browsing and 4K video playback.

Fanless operation and low power draw

The unit uses a passive cooling design so it runs silently without any moving parts, making it suitable for living-room or bedroom placement. The low-power Celeron processor keeps electricity consumption minimal during typical office tasks and media streaming. Gigabit Ethernet and dual-band Wi-Fi provide stable wired or wireless connectivity, while Bluetooth 4.2 handles peripherals such as keyboards, mice or headphones without cables.

Expandable storage and triple-display support

A 2.5-inch SATA bay accepts an additional hard drive or SSD up to 2TB, and a micro SD slot takes cards up to 128GB for quick file transfers. Video output comes from two HDMI ports and one VGA port, allowing up to three monitors to be driven simultaneously for multitasking or digital-signage setups. Four USB ports (two 2.0 and two 3.0) give plenty of room for external drives, webcams or other accessories.

Questions about this item

How do I install a 2.5-inch SATA drive in this mini PC and what step do people miss?

Open the case, connect the drive to the internal SATA port and secure it with screws, then initialise the new volume in Windows Disk Management so the 2 TB capacity becomes usable.

What maintenance or replacement will the built-in 6 GB DDR3 and 120 GB mSATA SSD need later?

The soldered 6 GB DDR3 cannot be upgraded; the 120 GB mSATA SSD can be swapped for a larger mSATA drive when space runs low.

What limit appears first during sustained 4K playback on the J3455?

The processor bursts to 2.3 GHz but drops back to 1.5 GHz under continuous load, so thermal throttling becomes the bottleneck before the Gigabit Ethernet or dual HDMI outputs saturate.
