eRacks Systems Tech Blog

Open Source Experts Since 1999

In 2015 we published a page called Components We Use, prompted by the broker emails that arrive in our inbox four or five times a week: “clean pull” hard drives by the pallet, bank wire only, 90-day warranty if you’re lucky. The message of that page was one sentence: every new eRacks system is built from 100% new, factory-fresh components, full stop.

A decade later the emails still come, but the merchandise has evolved. This week’s version offered current-generation AMD EPYC server processors, “brand new”, at 50 to 70 percent below any plausible new-part price. So we rewrote the page for 2026, and the new material is worth a blog post of its own, because knowing this trick can save you real money and real pain.

The vendor-locked CPU trick

Modern AMD EPYC processors include a security feature called Platform Secure Boot (PSB for short). When a large vendor like Dell, or a cloud data center, first powers a chip in one of their servers, PSB burns one-time fuses inside the processor that bind it permanently to that vendor’s firmware. That chip will now boot only on that vendor’s motherboards. Forever. There is no unlock.

When those servers are decommissioned, the pulled CPUs flow into the gray market, where brokers list them as “brand new” at half price. Buy one for a custom build and you own a very expensive paperweight: it will never POST (pass the power-on self-test) on a Supermicro, ASUS, or any other standard board. The discount is the tell. A price that looks impossible through authorized distribution usually is.

What we do instead

The refreshed page spells out our sourcing practice in full, and it is the same one we have followed since 1999:

  • Authorized US distribution only, so every manufacturer warranty passes through to you intact.
  • Multi-source price and availability verification before we quote or set a default. When a part goes supply-constrained, as several high-capacity drives have in the current shortage, we mark it subject to availability or move it to quote-only instead of pretending it ships tomorrow.
  • Quality brands, qualified by us: Supermicro and ASUS boards, Intel Xeon and AMD EPYC/Ryzen/Threadripper processors, Seagate, WD, and Toshiba drives (CMR only in our NAS lines), Samsung enterprise SSDs, Intel Arc and NVIDIA GPUs, Broadcom/LSI controllers.
  • 72-hour burn-in under full load on every system before it ships. A component that fails burn-in gets replaced, and the clock starts over.

None of this is new policy. What is new is the page saying it plainly for 2026, with the vendor-lock mechanics explained, so that when one of those emails lands in YOUR inbox, you know exactly what is being sold.
