HP Z1 Entry Tower G5 | Intel Core i7 9th Gen | 8GB DDR4 RAM | 500GB HDD | Intel UHD Graphics 630
A carefully maintained import for CAD drafting, architectural modelling, and heavy spreadsheet work in Nairobi, at a fraction of new-unit cost.
Condition: New
Note: price and availability are subject to change without prior notice
HP Z1 Entry Tower G5 is now available at Mascom International for KSh 46,000, configured with a 9th generation Intel Core i7 processor, 8GB of DDR4-2666 memory, and a 500GB 7200 rpm hard drive. This is a certified Z-series workstation chassis rather than a repurposed office PC, and the HP Z1 Entry Tower G5 arrives as a carefully maintained international import, never deployed locally in Kenya. You can watch the unit boot before paying at our Nairobi CBD store, Old Mutual Building, First Floor Room 4, Kimathi Street. The HP Z1 Entry Tower G5 runs on the Intel Q370 chipset with Intel UHD Graphics 630 onboard.
Architects, quantity surveyors, and CAD drafters across Nairobi face the same squeeze. Consumer desktops stall on 3D models, while a new workstation costs three to four times this figure. The HP Z1 Entry Tower G5 answers that with eight physical processor cores, four memory slots, and full-size PCIe expansion. Accounting teams working through heavy QuickBooks or Sage files, editors cutting 1080p footage, and software developers compiling code all get a tower designed for eight-hour daily loads. Small design studios in Westlands and Kilimani run this class of machine as a shared render and file station.
Unlike traditional electronics retailers in Kenya, Mascom International states exactly which components sit inside the case before you pay. Buyers throughout Kenya tell us the gap between a used workstation and a used office tower shows in year three, when the workstation power supply and steel chassis are still going. The HP Z1 Entry Tower G5 carries an internal supply rated up to 92% efficiency, a solenoid lock, and a hood sensor that flags case entry. Test one at Kimathi Street between Monday and Saturday, 9:00 AM to 7:00 PM, or order it for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the HP Z1 Entry Tower G5
Is this HP Z1 Entry Tower G5 used or refurbished?
It is used, not refurbished. The tower was lightly used internationally in an office or studio setting and never deployed locally in Kenya. Refurbished units have been stripped, repaired, and rebuilt by a third party. A used import has had one prior owner and a full functional test on arrival. Mascom International checks the processor, memory, drive, every port, and the power supply before listing. Light cosmetic marks on the steel panels are possible; every electrical component works or the unit never reaches our shelf.
Is a 9th generation Core i7 still worth buying today?
Yes, for work that values core count over the newest instruction set. This Core i7 carries eight physical cores and 12MB of cache, with turbo clocks up to 4.7GHz. That matches or beats many current mid-range laptop chips on sustained multi-core jobs like rendering, compiling, and recalculating large spreadsheets, because a tower cooler never throttles the way a thin laptop does. Where it gives ground is encoding in newer codecs such as AV1, which has no hardware support on this chip.
Can the 500GB hard drive be swapped for an SSD?
Yes, and it is the first upgrade we recommend. The chassis carries two 3.5-inch bays, one 2.5-inch bay, and an M.2 2280 slot wired for PCIe NVMe storage. An NVMe SSD cuts Windows boot time from roughly 45 seconds to under 15 and removes the pause when opening large CAD drawings or Sage company files. Keep the 500GB mechanical drive as your archive volume for finished projects. Mascom International stocks both SATA and NVMe drives and fits them at the Kimathi Street counter.
How much memory does this workstation support?
Four DIMM slots take DDR4-2666 modules, and HP rates the board for up to 64GB in total. The unit ships with 8GB in a single slot, leaving three slots open, so moving to 16GB or 32GB costs far less than replacing the machine. Fitting two matching modules switches the board into dual-channel mode and lifts integrated graphics speed noticeably. AutoCAD 2D drafting sits comfortably on 16GB, while Revit, SolidWorks, and 4K photo work want 32GB.
Will it run AutoCAD, SolidWorks, or Revit without a graphics card?
AutoCAD 2D drafting and light 3D work run acceptably on the Intel UHD Graphics 630. SolidWorks and Revit will install and open, but both vendors certify discrete cards, and complex assemblies or large Revit models stutter without one. The Z1 chassis is ISV certified, meaning HP validated the platform with Autodesk and SolidWorks when paired with a supported card. Adding a used NVIDIA Quadro P620 fixes that for a small fraction of the price of a new workstation. Mascom International can source and fit a compatible card.
Which graphics cards physically fit this tower?
HP caps a single card at 75W here, so the card must draw all its power from the slot with no extra connector. That rules out RTX 3060-class hardware and rules in the NVIDIA Quadro P400, Quadro P620, GeForce GT 1030, and 75W versions of the GTX 1650. The full-length PCIe 3.0 x16 slot runs at full width, and a second x16 slot is wired as x4 for capture or storage cards. Fitting two cards drops the limit to 35W each.
Is the HP Z1 Entry Tower G5 worth KSh 46,000 in Kenya's market?
For anyone who needs eight cores and real expansion, yes. A new desktop at KSh 46,000 in Nairobi typically brings a four-core Core i3 or i5, two memory slots, a sealed low-wattage supply, and no upgrade path beyond RAM. This tower gives eight cores, four memory slots, four PCIe slots, three drive bays, and a case rated for continuous professional loads. The trade-off is honest: it is a 2019 platform on a mechanical boot drive. Add an SSD and it outruns most new machines at this price.
Does it come with a monitor, keyboard, and mouse?
No. The tower and power cord are what you buy, which keeps the figure at KSh 46,000 instead of bundling peripherals you may already own. Mascom International stocks 22-inch and 24-inch monitors, USB keyboards, and mice, and we price a complete setup at the counter. The rear panel carries two DisplayPort 1.2 outputs plus a configurable third video port, so a dual-monitor drafting station needs only cables. HDMI and VGA adapters are available in store.
How does it cope with Nairobi power cuts?
Pair it with a UPS rated at 850VA or higher. The internal supply runs at up to 92% efficiency with active power factor correction, which tolerates the voltage sag common on some Nairobi and upcountry lines better than cheap consumer units do. A mechanical hard drive is the part most at risk during a sudden cut, which is a second argument for an SSD. Draw sits near 60W idle and 150W under load, so an 850VA unit buys several minutes to save and shut down.
