We selected these options because their specifications overlap with the original. All listed machines include Windows 11 Pro and 16GB of RAM. Some models offer larger monitors or more storage capacity. Others provide a standard tower size instead of a micro chassis. You can choose based on your need for screen real estate or physical footprint.

Our top pick: Lenovo ThinkCentre Tiny Intel i5 Desktop.
How these PCs differ
HP ProDesk SFF Core i5 Desktop
The HP ProDesk 600 G2 SFF offers a standard tower form factor instead of a tiny box. You get the same 16GB RAM and 256GB SSD with Windows 11 Pro, but in a larger chassis measuring 13.8 by 5.91 by 13.8 inches. This size allows for easier internal upgrades and better airflow than the Lenovo M900. It suits users who need more space for components but still want a reliable office machine. You trade the Lenovo’s ultra-compact 7-inch footprint for standard tower convenience and accessibility.
HP ProDesk Mini PC with 16GB RAM
The HP ProDesk 600 G4 Mini provides a compact alternative with identical 16GB RAM and 256GB SSD storage. Like the Lenovo, it runs Windows 11 Pro and targets office workstations. The key difference lies in the specific model generation, with the G4 offering potentially newer internal components than the M900. You retain the space-saving benefits of a small form factor while getting a comparable memory setup. This option works well if you prefer HP’s design language or need specific HP connectivity options for your desk setup.
HP ProDesk 600 G3 Mini PC
The HP ProDesk 600 G3 Mini features an older i5-7500T processor compared to the Lenovo’s i5-6500T. It still includes 16GB RAM and a 256GB SSD with Windows 11 Pro. The G3 model is slightly larger, measuring 17 by 9 by 19 inches, which may affect your desk space planning. It serves users who need a budget-friendly mini PC for multitasking and media playback. You get a reliable refurbished system for office duties, though the physical dimensions are significantly larger than the Lenovo’s tiny profile.
The HP ProDesk 600 G4 Mini offers a lower 8GB RAM configuration compared to the Lenovo’s 16GB. It keeps the 256GB SSD and Windows 11 Pro for office use. This reduction in memory makes it less suitable for heavy multitasking than the M900. However, it remains a secure, compact system for standard dual-monitor setups. You save space and potentially cost by accepting less RAM. This choice fits users who prioritize a small footprint and basic office tasks over extensive memory capacity.
Dell OptiPlex Micro Core i5 Desktop
The Dell OptiPlex 3070 Micro provides double the storage of the Lenovo, offering a 512GB SSD instead of 256GB. It matches the 16GB RAM and Windows 11 Pro setup. The compact Micro form factor is similar in size to the Lenovo Tiny, measuring 13.3 by 4 by 12.1 inches. This extra storage space benefits users who need more room for files and applications without expanding their desk footprint. You get a solid office machine with greater data capacity in a similarly tight space.
The Dell OptiPlex 3080 Micro uses a newer 10th Gen i5-10500T processor, which is faster than the Lenovo’s 6th Gen i5-6500T. It includes 8GB RAM and a 256GB SSD with Windows 11 Pro. The compact size measures 7 by 1.4 by 7 inches, making it very slim. You gain better processing power for business applications but sacrifice the Lenovo’s 16GB RAM. This model suits users who prioritize modern CPU performance and a minimal profile over higher memory totals for office multitasking.
