Refurbished OptiPlex 5070-SFF business desktop

The refurbished Dell OptiPlex 5070-SFF is a compact business desktop built around an Intel Core i7-9700 3.00 GHz eight-core processor with 12 MB L3 cache. It ships with 32 GB DDR4 memory and a 500 GB M.2 NVMe SSD. Windows 11 Pro 64-bit is pre-installed. Integrated Intel UHD Graphics 630 drives up to two DisplayPort monitors.

Front USB 3.1 Gen 2 Type-C

The front panel adds one USB 3.1 Gen 1 port, two USB 2.0 ports and a single USB 3.1 Gen 2 Type-C port plus a headset jack. The rear supplies four USB 3.1 Gen 1 ports, two USB 2.0 ports, one RJ45 port, two audio jacks and two DisplayPort outputs. No optical drive is fitted, so software installs rely on USB or network sources.

Slim 11.40 x 3.70 x 11.50 inch chassis limits

The small-form-factor case measures 11.40 by 3.70 by 11.50 inches and weighs 11.57 lbs, restricting internal upgrades to low-profile cards and a single M.2 slot. Integrated graphics share system memory and lack discrete video outputs beyond DisplayPort. Buyers needing additional drive bays, full-height add-in cards or more than two native video outputs should consider a larger form factor.

Questions about this item

How long before the 500 GB NVMe SSD needs replacement under heavy write workloads?

The 500 GB NVMe SSD has no moving parts, so its lifespan depends on total data written rather than a fixed schedule; typical endurance ratings for drives of this capacity exceed several hundred terabytes written.

What limits sustained performance first when all 8 cores of the i7-9700 run at 3.00 GHz continuously?

The Slim Form Factor chassis and integrated UHD 630 graphics share a compact cooling solution, so thermal headroom becomes the limiting factor during prolonged multi-core workloads.

How loud and hot does the 5070-SFF get when running all day with the i7-9700 and 32 GB DDR4?

The small 11.40" x 3.70" x 11.50" case uses a single system fan; under continuous load the fan ramps up to an audible level and exhaust air becomes noticeably warm.
