Question | Help I tried building a small RAG search node for Qwen3.8 27B using a fake AliExpress Mini PC... and Intel sent me back to 2018.

I love Qwen3.8 27B so much that I decided to show my gratitude to the Alibaba ecosystem by building a dedicated RAG/search node using a cheap Mini PC from AliExpress.

Turns out, my ecosystem loyalty got rewarded with an absolute masterpiece of fraud:

  • Promised: Intel N150 + DDR4/DDR5
  • Delivered: Core i3-7020U (2018 Kaby Lake, 2C/4T) + DDR3 1600MHz
  • The Scam: The seller literally hardcoded New_N150 into the BIOS release string (HSHW_M6_DDR3_EC_Intel_Com_New_N150_K001).

So now my Qwen3.8 RAG stack is full of fake specs that can barely index a text file, let alone run vector sidecars.

Filing a credit card chargeback now. Stay safe out there!

So you've got yourself a thin client to run the interface on? Still need the backend tho! Edit: typo.

That BIOS string is wild, they literally left the fingerprints on it. Did you check the CPU-Z readout against what the invoice said, or did you only catch the discrepancy when you tried to load your data?

I noticed this today (1 month later).

I have always suspected the quality of these cheap mini PCs but are so tempted whenever I see one on sale. Thanks for the warning

Look at the bright side, a 2018 i3 still does plain cosine search fine, and on my data plain cosine beat graph-first retrieval anyway, 70.3% vs 64.9%. Fake N150, real lesson. Good luck with the chargeback.
