Extended Case: Gumi Hosting Expansion

A 200-rack facility near Gumi planned to onboard forty used S19j Pro units purchased through a broker in Shenzhen. Page Sequoiaway ran a depot assessment over two days, identifying three hash board revisions in the same advertised lot. Two revisions had fan shroud mounts incompatible with locally stocked cooling modules.

The client renegotiated the purchase, excluding twelve units, and stocked the correct fan assemblies before installation. Downtime during the first month was limited to two boards—both failures on units they already knew carried a higher-risk revision. Operations lead noted the report was “dense but usable on the shop floor.”

Extended Case: Daegu Basement Farm

A six-person family operation running mixed Whatsminer and GPU rigs requested a spare parts trace only. They lacked capital for a full assessment. The trace report flagged a PSU model sole-sourced through a distributor with sixty-day lead times. They ordered two spare PSUs immediately and avoided a twelve-day outage when one failed in August heat.

Testimonials

We needed someone who would say which fan SKU actually sits in the Busan warehouse, not on a spec sheet. Han photographed the boxes. That alone saved us a wrong order.

— Jae-won Lee, 45-unit farm, Busan

The hash rate session proved our hosting provider was not throttling us—the units simply ran hot because intake filters were never swapped. Embarrassing, but cheaper than lawsuits.

— Marcus Holt, remote investor, UK

Report formatting is stark and old-fashioned. I like that. Less marketing, more part numbers. Wish the travel fee to our rural site had been estimated lower upfront, though the final invoice matched the quote they sent after photos.

— Soo-min Han, agricultural co-op mining pilot, Andong

They declined to assess a batch below 0.05 TH/s legacy units and explained why spare parts were effectively extinct. Honest, even when it cost them the job.
