Ideal for users looking for an affordable second PC for basic tasks.

📋 Technical Specifications

🏗️ Design and Construction Quality

Ultra-compact format

The Dell Optiplex 3040M (rebranded as PANAMEMORY) features an  extremely compact micro design  measuring just 18.2 x 17.6 x 3.6 cm, similar in size to a paperback book. This form factor makes it an ideal choice for small spaces, VESA mounting behind a monitor, or as a secondary PC in offices.

Materials and Construction

The chassis is made of  durable, enterprise-grade  Dell black plastic with a matte finish that minimizes fingerprints. Although it's a refurbished unit, the Optiplex series is known for its durability and modular design, which simplifies maintenance. The chassis includes passive ventilation grilles on the sides and weighs between 1.28 and 1.41 kg, making it easily portable.

Ease of Service

One notable advantage is its  modular and easily upgradeable design . According to Dell's official manual, you can access the internal components (RAM, storage) without special tools, allowing you to expand the memory up to 16GB or add an additional SSD.

🖥️ Screen and Multimedia

Dual 4K Video Output

The Optiplex 3040M supports  dual-monitor setups up to 4K resolution  via its HDMI 1.4 and DisplayPort 1.2 ports. This is ideal for office environments where multitasking with multiple displays is required. However, the integrated Intel HD Graphics 530 GPU has limitations with native 4K content.

Multimedia Performance

For  1080p video playback,  the device performs flawlessly without stuttering or interruptions. In real-world testing, users report that YouTube, Netflix, and other streaming services run smoothly in Full HD. For  4K content , the i3-6100 processor can play it, but at a reduced resolution of 1080p to maintain smooth playback.

Audio

It includes a combo audio output (headphones/microphone) and a standard line output. The audio is basic, sufficient for video conferencing and casual multimedia, without premium features or an optical output.

⚡ Performance and Software

Processor Power

The  Intel Core i3-6100  (6th generation, 2015) offers 2 physical cores and 4 threads at 3.7 GHz. This processor is sufficient for:

✅  Tasks he handles well:

• Multi-tabbed web browsing

• Office suite (Word, Excel, PowerPoint)

• Video conferencing (Zoom, Teams, Google Meet)

• 1080p multimedia playback

• Basic document and image editing

❌  Limitations:

• Modern gaming (casual or retro games only)

• 4K video editing

• 3D Rendering

• Intensive multitasking with demanding applications

Windows 11 Pro: The Controversy

⚠️ Important:  The i3-6100  does NOT meet the official  Windows 11 requirements , which require 8th generation Intel processors or higher. This means that Windows 11 was installed by bypassing restrictions.

Consequences:

• No guarantee of future updates from Microsoft

• Possible system instability

• Without official technical support

• Some anti-cheat programs may not work.

Recommendation:  Consider downgrading to Windows 10 Pro (officially supported) or be prepared for potential upgrade issues.

SSD storage

The  128GB SSD  provides fast boot times (less than 15 seconds) and responsive system performance. However, 128GB is  just enough for the operating system and basic applications . After installing Windows 11 and essential programs, approximately 60-80GB will remain free. It is expandable via the M.2 bay or by replacing the primary SSD.

RAM

The  8GB DDR3L RAM  operates at 1600 MHz, sufficient for office use with 5-10 browser tabs open simultaneously. It's expandable up to 16GB (2 DIMM slots), recommended if you plan on intensive multitasking or keeping multiple applications open.

🔋 Electricity Consumption

Energy Efficiency

With an  external 65W power supply , the Optiplex 3040M is extremely efficient. In real-world tests:

• Standby power consumption:  8-12W

• Power consumption under load:  35-45W

• Maximum power consumption:  65W

This translates to an  annual electricity cost of approximately €15-20  running for 8 hours a day (at €0.15/kWh). Compared to a traditional tower PC (150-300W), the energy savings are significant.

Temperature and Noise

The system uses  passive cooling and a small fan  that remains quiet during basic tasks. Only under sustained load does the fan become audible, but not to an annoying degree. The idle temperature is around 35-40°C, reaching 60-70°C under load.

🔌 Connectivity and Extras

Ports and Connections

The port layout is generous for a micro form factor, allowing you to connect  multiple peripherals without needing a USB hub .

Wireless Connectivity

✅  Built-in WiFi  (likely 802.11ac)
✅  Bluetooth  for wireless peripherals
✅  Gigabit Ethernet  for maximum stability

Extras and Features

❌ Does not include an SD card reader
❌ No USB-C port
❌ No optical drive (DVD/CD)
❌ No IP rating (not dust/water resistant)
❌ No fingerprint reader
❌ No 5G/LTE support

The approach is purely functional without modern premium features.

Final Verdict: ⭐⭐⭐½ (3.5/5)

The  PANAMEMORY Mini PC Optiplex 3040M, priced at €119,  offers  excellent value for money for basic office and multimedia tasks . It's a solid option if you understand its limitations (2015 hardware, unofficial Windows 11, no gaming capabilities) and are looking for a compact and efficient machine for everyday use.
