What Does "Desktop Computer PC Only" Mean?
A "desktop computer PC only" listing means you receive the computer itself — the system unit — without a monitor, keyboard, mouse, or operating-system installation media. You supply your own display and peripherals, and the machine connects over standard video outputs such as HDMI or VGA. This is the most common way to buy computers for offices, kiosks and industrial control rooms, because most buyers already have screens and input devices, or want to reuse them across a fleet of machines.
Modern "PC only" systems are no longer the bulky towers of the past. They are compact boxes that can be mounted behind a monitor, on a DIN rail, inside a control cabinet, or under a desk. Many are fanless, using the chassis itself as a heat sink, which removes the single most common failure point in dusty or high-vibration environments.
Key Specifications to Consider
When comparing desktop PCs supplied without peripherals, the specifications below determine what workloads the machine can handle.
| Specification | Typical Range | Why It Matters |
|---|---|---|
| Processor | Intel Celeron / N-series, Core i3, i5 | Determines multitasking and compute headroom |
| Cores / Threads | 4 to 12 cores | More cores help with VMs, databases and multi-app use |
| Memory (RAM) | 4 GB to 64 GB DDR4/DDR5 | 8–16 GB suits office work; 32 GB+ for virtualisation |
| Storage | 128 GB to 1 TB SSD | SSDs give fast boot and quiet, shock-resistant operation |
| Graphics | Integrated Intel UHD/Iris Xe | Supports dual 4K displays on newer platforms |
| Video Outputs | 1–2 x HDMI, VGA, DisplayPort | Needed for dual-screen setups |
| Networking | Gigabit Ethernet, optional dual LAN | Single LAN for offices; dual LAN for gateways |
| Serial Ports | Optional DB9 RS-232/RS-485 | Essential for PLCs, scales and legacy equipment |
| Cooling | Fanless or active | Fanless suits dust, heat and 24/7 operation |
| Mounting | VESA, DIN rail, wall bracket | Simplifies installation in cabinets and kiosks |
A system with an Intel Core i3-1215U, for example, offers 6 cores and up to 4.4 GHz, which is more than enough
