Built for Kenya's accountants, cyber cafe operators, school computer labs, church media teams, and small offices that buy three or four machines at a time, the HP ProDesk 600 G4 SFF answers a common budget problem. A new i7 tower lands around KSh 90,000 in Nairobi, which pushes most small businesses toward slow dual-core machines instead. The HP ProDesk 600 G4 SFF gives twelve processing threads to teams running QuickBooks, Sage, heavy Excel workbooks, and twenty Chrome tabs at once. Shops handling KRA iTax filings, payroll runs, and Zoom meetings on the same machine feel the difference immediately.

Unlike other electronics retailers in Kenya who sell used towers with no testing record, Mascom International benches every HP ProDesk 600 G4 SFF before it reaches the shelf and covers it for 6 months. Buyers across Kenya tell us the four memory slots and the spare drive mounting matter most, since a KSh 4,500 memory module or an SSD swap keeps the machine useful for years. Walk in to Kimathi Street and run the HP ProDesk 600 G4 SFF yourself before paying, or order for pay-on-arrival delivery to Nakuru, Kisumu, Eldoret, Mombasa, or any county office where your team works.

Used, not refurbished, and the distinction matters. This HP ProDesk 600 G4 SFF is a carefully maintained international import that served an office abroad, then reached Nairobi and passed our bench testing. Nothing was rebuilt, resprayed, or fitted with replacement parts to disguise wear. Refurbished machines have had components swapped out and are then resold as near-new. We describe this tower as clean used condition, tell you exactly what it is, and cover it for 6 months.

The Core i7 inside runs six physical cores and twelve threads at 3.2GHz, climbing to 4.6GHz under load. In practical terms it handles Sage 50, QuickBooks, Excel models with 50,000 rows, twenty Chrome tabs, and a Zoom call at the same time. PassMark data places it roughly 47 percent ahead of the older four-core i7-7700 in multi-threaded work. Accountants closing books and clerks running iTax submissions stop waiting on the machine during month-end deadlines.

8GB of DDR4-2666 covers Microsoft Office, accounting software, and normal browsing comfortably. The HP ProDesk 600 G4 SFF has four memory slots and accepts up to 64GB in total, leaving three free slots to grow into. One extra 8GB module costs roughly KSh 4,500 locally and brings dual-channel operation, which lifts everyday responsiveness. Offices running virtual machines, AutoCAD, or large Access databases should budget for 16GB or 32GB. The side panel opens without tools.

Yes, and it is the single best upgrade on this tower. The 500GB SATA hard drive spins at 7200rpm and reads around 120MB per second, so Windows takes 40 to 60 seconds to reach the desktop. A 256GB or 512GB SATA SSD reads near 550MB per second and cuts that to roughly 15 seconds. The chassis also carries a spare M.2 2280 slot for an NVMe drive, letting you keep the hard drive for file storage.

Yes. Microsoft requires an 8th Generation Intel processor or newer, TPM 2.0, UEFI firmware, and Secure Boot, and the HP ProDesk 600 G4 SFF meets all four through its embedded TPM 2.0 chip and Q370 board. Many Kenyan offices still run Windows 10 on these towers, which stopped receiving security updates in October 2025. Upgrading in place is straightforward. Ask our Kimathi Street team to confirm the operating system installed on the exact unit before you pay.

Yes. Two DisplayPort 1.2 outputs sit at the rear and run two screens at 4K and 60Hz each, or three displays when the optional HDMI or VGA flex port is fitted. Accounting teams keep Sage on one panel and email on the other. Architects park reference drawings beside their drawing window. Intel UHD Graphics 630 handles that dual-screen load without a separate card, and DisplayPort to HDMI adapters cost roughly KSh 1,200 in Nairobi.

Yes, within the limits of a small chassis. One PCIe 3.0 x16 slot and one PCIe 3.0 x4 slot are available, but the 180W internal supply and low-profile height mean the card must draw its power from the slot alone. A low-profile GTX 1650 or Radeon RX 6400 fits comfortably and handles Adobe Premiere timelines, SketchUp, and 1080p gaming. Cards needing a six-pin power connector will not work here. Our team confirms clearance before you buy.

It suits both well. The metal chassis, 180W efficient supply, and business-class parts tolerate long daily hours better than consumer towers, and the 9.5 by 27 by 29.6 centimetre footprint fits tight desks. DriveLock, BIOS passwords, and USB port disablement through the BIOS let administrators lock machines down for student use. Buying six or ten units together also lets us quote batch pricing and supply a matching invoice for your tax claims.

At KSh 26,000 you get six cores and twelve threads for less than a third of what a comparable new i7 tower costs in Nairobi. New machines in this price band ship with dual-core Celeron or Pentium chips and slower storage. Customers across Nairobi report that adding an SSD and a second memory module for roughly KSh 9,000 produces a machine that outruns new KSh 60,000 desktops. The 6-month warranty covers the risk.

Three ways to order:

Every HP ProDesk 600 G4 SFF leaves our bench with the 6-month Mascom warranty stated above, and claims are handled at our Nairobi CBD service desk.

Keyboards, mice, monitors, memory, and SSD upgrades sit in the same shop, so a complete workstation can leave with you in one trip. Mascom International has built its name on accurate specifications, current Kenyan pricing, and after-sales support you can walk into.
