Ryzen 5655G Small Business Desktop PC – Built in the UK
The Advanced Entry Small Business PC is a Ryzen 5655G small business desktop PC for office administration, email, web-based business tools and everyday accounts work.
Built around the AMD Ryzen 5 PRO 5655G, this Ryzen 5655G small business desktop PC gives a small office a six-core processor, integrated graphics and a fast NVMe SSD in a compact mATX mini tower. It runs genuine Windows 11 Professional, so it is ready for business use on first start-up. Because the graphics are integrated into the processor, there is no separate graphics card to buy, fit or replace. That keeps the build simple and the cost sensible for desks that need reliable day-to-day performance rather than workstation power.
The Advanced Entry Small Business PC is built on an AMD Ryzen 5 PRO 5655G processor with 6 cores and 12 threads, integrated Radeon graphics, 8GB of DDR4 3200MHz memory and a 256GB M.2 PCIe 3.0 NVMe SSD. It runs genuine, pre-installed Microsoft Windows 11 Professional 64-bit and is covered by a 3-year parts and labour warranty.
Six-core Ryzen processor with integrated graphics
The AMD Ryzen 5 PRO 5655G is a 6-core, 12-thread processor with a 3.9GHz base clock, a 4.4GHz maximum turbo clock and 16MB of L3 cache. It suits the work most small businesses do all day: several browser tabs, email, documents, spreadsheets, accounting software and video calls running together. The integrated Radeon graphics handle the desktop and everyday display work. The Gigabyte A520M H ARGB motherboard provides one DisplayPort 1.4 output and one HDMI 2.1 output, so the system can drive two monitors. An AMD stock air cooler keeps the processor in check, so there is no liquid cooling to maintain.
Memory and NVMe storage
The PC comes with 8GB of DDR4 3200MHz memory fitted as a single 8GB module. The Gigabyte A520M H ARGB motherboard has two DIMM slots and supports up to 64GB, so one slot is free for a second module later. The operating system and applications sit on a 256GB M.2 PCIe 3.0 NVMe SSD rated at 3000MB/s read and 1300MB/s write. That matches the motherboard’s PCIe 3.0 x4 M.2 slot, so the drive runs at its rated speed. Windows starts quickly and files open without the wait of a traditional hard drive. You can change the memory and storage in the configurator if your team works with larger files or needs more room.
Windows 11 Professional for business use
Windows 11 Professional is genuine and pre-installed. Pro adds the features a business actually uses: BitLocker drive encryption to protect company data if a PC is lost, Remote Desktop so the PC can be reached from another location, and the ability to join a company domain. Home editions do not offer these, which is why Pro is the sensible choice for a small business. Windows is supplied genuine and pre-installed, and activation is completed by the user on first use.
Compact Contour Contender mATX case
The system is housed in the Contour Contender mATX Workstation case in silver, a solid steel mini tower measuring 410mm deep, 182mm wide and 353mm high. It fits under or on a desk without dominating it. Inside there are mounts for three 3.5in drives and one 2.5in drive, and four SATA 6Gb/s ports on the motherboard, so extra storage can be added later. Power comes from a Contour 300W ATX power supply, sized for a system with integrated graphics.
Connectivity and ports
The rear panel has a 1GbE Ethernet port alongside the motherboard’s DisplayPort 1.4 and HDMI 2.1 video outputs. The front panel adds two USB 2.0 ports, a headphone jack and a microphone jack. Built-in audio is High Definition 7.1 from the motherboard’s Realtek audio. Networking is wired only, with no Wi-Fi built in. If you need wireless, look for a Wi-Fi option in the configurator or call 0151 317 9860. No keyboard or mouse is included, so choose them from the accessories below.
Ideal for
- Staff desks in a small office running email, documents and spreadsheets
- Reception, front desk and customer-facing counters
- Bookkeeping, accounts and general administration
- Home offices that need a dependable, compact Windows 11 Pro PC
- Dual-screen admin desks using the DisplayPort and HDMI outputs
For a Ryzen 5655G small business desktop PC with six cores, genuine Windows 11 Professional and an NVMe SSD, the Advanced Entry Small Business PC is a well-balanced starting point. It covers everyday office work comfortably, and the configurator lets you adjust the memory, storage and other parts to suit your team.
Built to order and tested in the UK by Punch Technology, every system comes with a 3-year parts and labour warranty, backed by over 30 years of PC building experience. The estimated lead time for your configuration is shown when you order.

What is the Advanced Entry Small Business PC best for?
The Advanced Entry Small Business PC is primarily a general office and administration computer for one user at a desk. It covers email, word processing, spreadsheets, web-based business tools, cloud storage and video calls. The six-core processor and NVMe drive keep Windows responsive when several of these are open at once.
Typical roles include reception and front desk work, bookkeeping and accounts, order processing, scheduling and general back-office administration. It also suits a home office that needs a compact PC running Windows 11 Professional. The 8GB of memory and integrated graphics are sized for office work. Video editing, CAD, 3D rendering and other graphics-heavy workloads need a more powerful system, and Punch’s workstation and video editing ranges are built for those.
Where does the Advanced Entry Small Business PC sit in the range?
Below it in the range, the AMD Ryzen Business PC uses the same Ryzen 5 PRO 5655G with 16GB of DDR4 3200MHz memory and a 500GB M.2 PCIe 4.0 NVMe SSD. The Core i5 Small Form Factor Education PC is an Intel alternative with a Core i5-14400, 16GB of memory and a 256GB NVMe SSD. Above it, the Entry Plus Small Business PC also uses the Ryzen 5 PRO 5655G with 8GB of memory, but stores data on a 240GB Crucial BX500 2.5in SATA SSD. The Punch Value Plus Small Business Desktop pairs an Intel Core i5-12400 with 8GB of memory and the same SATA drive. The Advanced Entry Small Business PC is the one in this group with an NVMe system drive.
Frequently Asked Questions
What software can the Advanced Entry Small Business PC run?
It runs everyday business software on Windows 11 Professional 64-bit, including office suites, email clients, web browsers, accounting and bookkeeping packages, PDF tools and video-calling apps. The six-core Ryzen 5 PRO 5655G with 8GB of memory and an NVMe SSD handles several of these at once. It is not intended for video editing, CAD or 3D rendering.
Why does this PC come with Windows 11 Professional?
Windows 11 Professional adds business features that Home does not include. These are BitLocker drive encryption, Remote Desktop and the ability to join a company domain. The operating system is genuine and pre-installed, with activation completed by the user on first use.
Can the Advanced Entry Small Business PC run more than one monitor?
Yes, it can drive two monitors using the DisplayPort 1.4 and HDMI 2.1 outputs on the motherboard. The Ryzen 5 PRO 5655G’s integrated graphics power them, so no separate graphics card is needed. Check which connectors your monitors use before you order, and see the Monitors and Cables buttons above for suitable accessories.
Can I add more memory or storage later?
Yes. The motherboard has two DIMM slots with one used, and supports up to 64GB of DDR4. The M.2 slot is occupied by the system SSD, but there are four SATA 6Gb/s ports and case mounts for three 3.5in drives and one 2.5in drive. You can also change the memory and storage in the configurator before you order.
Who is this PC best suited for?
It is best suited to small businesses, home offices and administrators who need a compact, dependable Windows 11 Professional desktop for email, documents, spreadsheets, accounts and web-based tools. It suits buyers who want a modern six-core processor and NVMe storage without paying for workstation-class graphics.
Does the Advanced Entry Small Business PC include Wi-Fi, a keyboard or a mouse?
