Compatibility checks before ordering

Verify that your monitor accepts the video connections available on this chassis and that your desk space fits a small form factor tower. The system uses DDR3 memory so any future upgrades must match that generation. Confirm your peripheral devices connect via USB or the legacy ports present on this model. The included USB Wi-Fi adapter provides wireless networking without occupying an internal slot.

Sustained load behaviour

Under continuous workloads the quad-core i7-4790 maintains its 3.60 GHz clock while the small form factor cooling manages thermal output within the chassis limits. The integrated Intel HD Graphics 4600 shares system memory during prolonged graphical tasks. The new 1TB SSD sustains read and write speeds without mechanical latency. Windows 10 Pro 64-bit handles background services steadily during extended sessions.
