Live inventory · Ships from Philadelphia
Bench-tested computing, networking & lab surplus — straight from the workbench.
Surplus and refurbished electronics, tested by an engineer and sold direct. A lot of it is cross-listed on eBay — here it's sold straight from the bench, often at a lower price. Plus a repair bench for vintage hi-fi and electronics.

Also selling as slashinburn on eBay — same gear. Buy direct here, often for a lower price.
Engineer-tested, not "powers on"
Every unit gets a bench check and a short report — what I tested and the actual numbers (SSD health, battery cycles, ports, audio channels) — plus real photos of the exact unit, serial plate included, sent on request. Never stock photos, never bait-and-switch.
Real-name accountability
Strommen Systems is a registered Pennsylvania LLC with a return policy, a working inbox, and a person behind it — not an anonymous flip account. PayPal and Venmo purchase protection back every order.
Computing & Laptops
ThinkPads, desktops, workstations, SSDs — wiped, tested, with a health report.
Network & Enterprise
Switches, routers, APs, rack gear. Powered up and port-checked, not "untested."
Lab & Test Equipment
Meters, supplies, scopes and surplus instruments — function-verified where possible.
Vintage Hi-Fi & Audio
Turntables, cassette decks, receivers — serviced on the bench, channels checked.
Browse the live catalog — pulled straight from current stock. Cross-listed gear is also on eBay; buy direct here, often for a lower price.

Ship it in or drop it off (Philadelphia / Huntington Valley). How repairs work →
The same automated bench, as a service: bulk hardware testing with per-serial reports, bulk imaging and provisioning (Windows or Linux), custom golden images, and NIST 800-88 aligned data wipes — for resellers, schools, and offices with a pallet of machines, not one. See fleet services →
The day job behind the bench: I'm an independent platform & AI engineer — Kubernetes, cloud-cost work, and AI agents wired into dev workflows for small teams. Separate from the shop, same person. See the consulting work →
