Refurbished Micro Tower Business Desktop

The Dell 5090 Micro Tower is a refurbished business desktop built around an Intel Core i7-10700T 8-core processor running at 2.0 GHz with 16 MB L3 cache. It ships with 32 GB of DDR4 memory and a 512 GB NVMe SSD. Windows 11 Pro 64-bit is pre-installed. A USB keyboard and USB mouse are included.

Connectivity and Form Factor Suitability

Five USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2 Type-C port, two DisplayPort 1.4 outputs, one RJ-45 Ethernet jack and one audio combo jack handle peripherals and dual displays. The Micro Tower chassis measures 7.17 x 1.42 x 7 inches, limiting internal expansion to low-profile cards and proprietary power supplies. Buyers who need full-height PCIe slots or standard ATX power supplies should look at a larger form factor.

Deciding Specification: 32 GB DDR4 Memory

The system provides 32 GB of DDR4 memory soldered or populated in the available slots. This capacity supports typical multi-application workloads and virtual machines. If the intended workload requires more than 32 GB of RAM, this unit cannot be upgraded beyond that limit and a different platform must be chosen.

Questions about this item

How do I install the 32GB DDR4 memory in the Micro Tower and what step is often missed?

Remove the side panel, align the notch on each DDR4 module with the slot key, press firmly until the retention clips click on both sides, then replace the panel before powering on.

What maintenance or replacement will the 512GB NVMe SSD need later?

The NVMe SSD has no moving parts; monitor SMART health in Windows 11 Pro and replace the drive only if reallocated-sector counts rise or capacity drops.

Which limit appears first during sustained loads on the 8-core i7-10700T?

The processor's thermal ceiling in the compact Micro Tower chassis is reached before the 16 MB L3 cache or memory bandwidth become bottlenecks.
