Looking for a Tiny/Mini/Micro PC with a full PCIe slot, ready to use? This is the listing for you.

What You Get:
✅ Thinkcentre Tiny m720q with Intel i3-8100T cpu
✅ 135 Watt (or greater) Power Supply
✅ Your choice of 256gb, 512gb, or 1Tb NVMe SSD
✅ PCIe riser and IO Shield bracket, installed and tested
✅ 16gb RAM*
✅ Genuine, bloat-free Windows 11 Pro (installed with Rufus)
✅ Wifi (m.2 card + internal antennas)
✅ Peace of mind that this machine has been fully stress tested end-to-end by an industry professional :)

*RAM ships as single-channel (1x16 instead of 2x8) unless you request otherwise. If you'd prefer 2x8, message me after purchase.

Inclusion of PCIe riser means removal of 2.5" drive tray and cable. If you'd prefer a system with the 2.5" drive tray, see my other offerings.

Testing Process:

This listing is for a lot of equivalent computers. Minor blemishes may vary unit to unit, but all are guaranteed fully functional.

I use a two-pass QA process. Individual components are tested when they arrive, and the final assembled product is tested before shipping.
  • Whole system, as assembled, undergoes the Lenovo full-unattended suite of self-check tests, including CPU, Motherboard, Storage, and RAM.
  • RAM undergoes memtest86 4-pass verification.
  • All physical ports are tested for basic function.
  • Wifi is tested for basic function.
  • Whole system is tested end-to-end with an operating system (either the one it ships with, or one loaded from USB).
Additionally, I test the PCIe slot by loading a storage device in a PCIe-to-m.2 riser and ensuring reasonable drive read/write benchmarks.

PCIe Expansion:
These machines include a PCIe slot with proprietary riser and IO shield bracket installed. This listing is meant for "home lab" enthusiasts, engineers, and students who want to tinker. The user is responsible for ensuring compatibility of any PCIe device they choose to install. Some PCIe devices may require thermal dissipation and/or electrical insulation modifications.

❗️Due to the tinkerer's nature of this product, returns are accepted only if the device arrives in a condition worse than advertised. Incompatibilities or damage caused from improper installation of a PCIe device or other motherboard peripheral are not valid grounds for return.

The IO Shield Bracket included may not fit with your chosen PCIe device, but in my testing, even when I haven't been able to fix the bracket to the PCIe card with a screw, the bracket has still provided structural support.

Lot of Equivalent Machines:
This is a listing for a lot of equivalent machines, built from used hardware and restored to a tested, working condition. The machine you receive may differ from one depicted in the photos. It may have minor cosmetic blemishes or replacement parts. If you have questions prior to purchase, I am happy to answer them. However, I offer no warranties or guarantees for the software installed.

Why buy from me?
I spent a decade working in systems administration and software development, leaving the industry to study environmental conservation. I think computers are groovy and e-waste is tragic. My goal is to sell you something you'll actually use: the longer these machines work well for someone, the less likely they are to end up in a landfill. :)
