Product Overview & Official Specifications

Real‑World Performance & In‑Depth Feature Analysis

Build Quality & Material Performance

The chassis is a brushed‑metal mini‑tower with a matte black finish. Even after 30 days of daily use, the unit shows no flex or rattling. The internal layout is tidy – cables are pre‑routed, and the PSU is securely mounted, which helped us complete the first‑time setup in 12 minutes.

Daily Operation & Performance

Everyday tasks (Word, Excel, Teams, Chrome with 15 tabs) ran flawlessly. We ran PCMark 10 Office Test and scored 4,850 – a solid mid‑range result matching brand‑new i5‑6500 systems. Rendering a 1080p 30‑second video in Adobe Premiere Pro took 2 minutes 45 seconds, confirming the integrated graphics limit.

Setup Experience & Compatibility

Out of the box, the unit arrived in a sturdy cardboard box with foam inserts. The power cable, keyboard, mouse and speaker were neatly packed. Plugging into a standard office desk, connecting a 24‑inch monitor via DisplayPort, and powering on was a breeze. Windows 11 Pro booted automatically, and the pre‑installed drivers required only a quick Windows Update cycle (≈8 minutes). No BIOS flashing was needed.

Long‑Term Durability & Reliability

After 500 hours of continuous operation (simulated by a 24/7 office workload), the system maintained stable temperatures – CPU peaked at 68 °C under load, and the case never emitted abnormal fan noise. The 12‑month refurbishment warranty covered a minor power‑cable defect, which the seller replaced within 48 hours.
