Intel Core i5-12400 Small Form Factor Business PC – Built in the UK
The Punch SlimStation SFF 12th Gen Desktop is an everyday i5-12400 small form factor business PC for office work, education and home working.
Space is often the first problem when you buy a desktop for an office, a classroom or a spare room, and the SlimStation is designed around that. It pairs a six-core, twelve-thread Intel Core i5-12400 processor with 8GB of DDR4 memory, a 500GB NVMe SSD and genuine, pre-installed Windows 11 Home inside the In Win CJ708 8L small form factor chassis. The result is an i5-12400 small form factor business PC that handles documents, spreadsheets, email, browser-based tools and everyday multitasking without taking over the desk. Because it is built to order, you can change the parts in the configurator before you buy.
The Punch SlimStation SFF 12th Gen Desktop is built on an Intel Core i5-12400 processor (6 cores, 12 threads, 2.5GHz base clock, 4.4GHz maximum turbo) with integrated graphics, on an MSI PRO H610M-E Micro-ATX motherboard. It has 8GB of DDR4 3200MHz memory in a single module, a 500GB M.2 NVMe SSD, an In Win 265W 80 Plus Bronze power supply and Microsoft Windows 11 Home 64-bit (genuine, pre-installed). Every system carries a 3-year parts and labour warranty.
Intel Core i5-12400 processor for everyday work
The Intel Core i5-12400 is a 12th generation processor on the LGA1700 socket with six cores and twelve threads. It runs at a 2.5GHz base clock and boosts to 4.4GHz, with 18MB of L3 cache. That gives office suites, web applications and several open windows the headroom they need, and the processor is cooled by Intel’s standard air cooler, so there is no separate cooler to specify.
Memory and NVMe storage
The system is fitted with 8GB of DDR4 3200MHz memory as a single 8GB module. The motherboard has two DIMM slots and supports up to 64GB, so one slot is free for a later upgrade. If you know your users keep many browser tabs and documents open at once, you can choose more memory in the configurator when you order.
Storage is a 500GB M.2 PCIe 4.0 NVMe SSD rated at 5000MB/s read and 3000MB/s write, which holds Windows and your applications. The M.2 slot on this motherboard is PCIe 3.0 x4, so in this build the drive runs at PCIe 3.0 speeds, below its rated figures. It is still NVMe storage for quick start-up and file access. The board also has four SATA 6Gb/s ports, none of them used, and no optical drive is fitted.
Integrated graphics for office and two-monitor work
There is no separate graphics card. Display output comes from the Intel graphics built into the processor, through one HDMI 1.4 port and one VGA port on the motherboard, which supports two monitors. That suits office applications, teaching and presentation work and everyday desktop use. It is not intended for 3D modelling, rendering or video editing.
In Win CJ708 8L case and cooling
The chassis is the black In Win CJ708 8L, a solid steel small form factor case measuring 305mm deep, 95mm wide and 290mm high. It is compact enough for a desk, a shelf or a tight office corner. The In Win 265W 80 Plus Bronze Flex ATX power supply is non-modular. The system is air-cooled by the Intel standard CPU cooler, with no liquid cooling and no extra case fans fitted.
Connectivity and ports
Wired networking is 1GbE through a Realtek RTL8111H LAN port. No Wi-Fi or Bluetooth is built in, so the system is wired-network only, and wireless options can be added when you configure the PC. There are ten USB ports in total. The rear has two Type-A 5Gbps ports and four USB 2.0 ports, and the front has two USB 3.0 and two USB 2.0 ports plus a headphone and microphone combo jack. Audio is High Definition Audio 7.1 from a Realtek ALC897 codec. No keyboard or mouse is included, so add them from the accessories below.
Ideal for
- Business desktops for staff in compact offices
- Home office setups
- Schools and education use
- Everyday productivity and multitasking
- Two-monitor desks where space is limited
For an i5-12400 small form factor business PC that is easy to place, comes with Windows 11 Home installed and carries a 3-year warranty, the Punch SlimStation SFF 12th Gen Desktop is a well-balanced choice. It combines a six-core processor, NVMe storage and two-monitor support in a small chassis. The configurator lets you adjust memory, storage and wireless before you order.
