📋 Key Technical Specifications

🎨 Design and Construction Quality

The MLLSE M6 features a compact, rectangular design. The casing is made of a combination of aluminum and ABS plastic, with prominent side vents to facilitate airflow. The result is a device that feels more robust than the brand's more affordable models.

The included VESA mount allows for clean installation behind the monitor, eliminating any visible traces on your desk. The three USB 3.2 ports are well distributed, although a USB-C port with full data transfer is noticeably absent  from a device at this price point. The matte black finish is understated and professional—the kind of device that doesn't draw attention but gets the job done.

🖥️ Screen and Multimedia

With dual HDMI 2.0 outputs, the M6 ​​effortlessly handles two 4K@60Hz monitors simultaneously, a task the i5-12450H processor and Intel Iris Xe GPU handle with ease. 4K video playback (H.265, VP9, ​​AV1) is smooth thanks to integrated hardware decoding. For Plex, Kodi, Netflix, or YouTube at maximum resolution, the M6 ​​is a perfect and quiet solution.

The integrated audio chip works via the 3.5mm jack, which is sufficient for headphones or desktop speakers. Don't expect a premium sound card, but it performs perfectly well for video conferencing, streaming music, and everyday video playback. If you're looking for a high-performance 4K media center for your living room, this device excels.

⚙️ Performance and Software

The Intel Core i5-12450H (Alder Lake) is a gaming laptop processor with 8 cores (4 P-cores + 4 E-cores) and 12 threads, reaching up to 4.4 GHz in Turbo Boost mode. It belongs to Intel's 12th generation hybrid architecture, meaning it combines high-performance cores (P-cores) with efficiency cores (E-cores), handling multitasking very well. Its PassMark score exceeds 14,000 points.

In daily use, opening 30 tabs in Chrome, having Zoom active, editing a document in Google Docs, and exporting a short video in the background is something the M6 ​​handles without flinching.

The Windows 11 Pro operating system comes pre-installed and activated, with no significant bloatware. Windows updates function normally, and the system responds quickly from the first boot.

⚡ Energy Consumption and Cables

The i5-12450H has a base TDP of 35-45W and can reach up to 95W in maximum boost mode, which is significantly more than the Ryzen 4300U.

In practice, the actual power consumption of the complete system under medium load is around 35-50W, and at idle it drops to about 8-12W. It's not the most energy-efficient mini PC, but for the power it offers, the consumption/performance ratio is very good.

The included charger is a proprietary DC adapter—not USB-C—so replacing it if lost requires finding a compatible one. For use in critical or continuous-duty environments, a small home UPS would be a worthwhile investment.

🌡️ Temperature and Noise (Actual Thermal)

The i5-12450H is a high-performance processor that generates more heat than lower-power chips, and the M6's active cooling system works accordingly. Under normal use, temperatures remain between 50-65°C with the fan audible but not bothersome. Under sustained load, such as rendering, long benchmarks, or PS3 emulation sessions, it can reach 80-88°C, without throttling thanks to the cooling system.

The noise level is moderate under heavy load, which is the trade-off for the extra power. At idle and during office work, the fan is barely audible. If you're looking for a completely silent unit for the living room, keep in mind that under heavy load, the M6 ​​will be audible at close range.

🔌 Connectivity and Extras

The MLLSE M6's connectivity is functional and modern, although with some notable omissions:

• 📶 WiFi 6 (802.11ax) — excellent wireless performance, ideal for congested networks

• 🔵 Bluetooth 5.2 — compatible with modern mice, keyboards, and headphones

• 🌐 Gigabit Ethernet — for a stable wired connection

• 🔌 3x USB-A 3.2 Gen1 (5 Gbps) — for fast peripherals and external storage

• 🖥️ 2x HDMI 2.0 — simultaneous dual 4K@60Hz monitor

• 🎧 3.5mm combo jack (audio + microphone)

What it lacks: USB-C with data (a notable omission at this price point), SD card reader, NFC, fingerprint reader, and IP certification. At this price, one would expect at least a USB-C Thunderbolt port or similar.

🔧 Expansion and Upgrades

One of the great advantages of the M6 ​​is its expandability flexibility:

• 🧠 RAM: 2 SO-DIMM DDR4 slots — expandable up to 64 GB (2×32 GB at 3200 MHz)

• 💾 Main SSD: M.2 PCIe 4.0 x4 2280 slot (High-speed NVMe) — replaceable with up to 2 TB

• ➕ Second SSD: Additional M.2 SATA3 2242 slot — allows you to add a second drive of up to 1 TB without sacrificing the main one

• 🐧 Linux compatible: Ubuntu, Fedora and derivatives work seamlessly with the i5-12450H

Having two M.2 slots is a real advantage: you can have the system on the fast NVMe and data storage on the secondary SATA, without needing external drives.

🆚 Comparison with Direct Competitors

The MLLSE M6's main rival is the Beelink SEi12, which offers identical hardware with better after-sales support and a more established reputation, at a similar or even lower price. The GEEKOM IT12 also competes directly and has the advantage of WiFi 6E. At €410, the M6 ​​needs to justify its price against these alternatives with equivalent hardware.
