Compact tower for everyday tasks

The Acer Aspire XC-840-UB11 is a small-form-factor desktop built around an Intel Celeron N4505 dual-core processor and 16GB of DDR4 2933 memory. It ships with Windows 11 Pro, a USB keyboard and mouse, and a 7-in-1 docking station that adds 1TB of external storage plus a 32GB MicroSD card. The system targets home users and small offices needing reliable web browsing, document work and HD media playback.

Straightforward setup with limited internal access

The tower arrives fully assembled; the supplier notes the seal is opened only for the RAM and SSD upgrades that are already installed. Front-facing USB and audio ports make peripheral connections simple, while the single RJ45 jack and Wi-Fi 6 handle networking. Buyers who want more internal drive bays or a discrete graphics card will find the compact chassis restrictive.

Steady low-power operation under continuous use

The N4505’s low thermal design keeps fan noise modest during long work sessions, and the integrated Intel UHD Graphics maintains smooth 5.1-channel surround playback over HDMI. Sustained multi-tasking stays responsive within the limits of the dual-core architecture. Users needing heavy rendering, large-scale compilation or extended gaming loads should look elsewhere.

Questions about this item

How can I confirm the Intel Celeron N4505 and 16GB DDR4 2933 are running correctly after first boot?

Open Task Manager to verify the Intel Celeron N4505 shows two cores and the memory reads 16GB DDR4 at 2933, then run a quick video to check Intel UHD Graphics output.

What accessories are included in the box and what must I purchase separately?

The package includes the tower, USB keyboard, USB mouse, a 7-in-1 docking station with 1TB storage, a 32GB MicroSD card with adapter, a Type-C data cable, a 3-in-1 charging cable and a suede cleaning cloth; a monitor and any extra cables are not included.

Which storage configuration suits me — the internal 2TB SSD or the 1TB docking station set?

The internal 2TB SSD provides fast boot and application load times, while the 1TB docking station adds portable capacity and extra ports for peripherals; both are supplied together.
