Origin

Appcypresscore Mining Review began when founder Ji-won Han spent a winter rewiring a Jamsil basement room for a client’s 0.06 TH/s row. Two units arrived with rail ears that did not clear the cabinet door, and the panel tripped on the third day of operation. The client asked for someone who would measure before ordering, not after.

That request became our practice: independent, written assessments of rack-ready mining hardware for operators who work in tight rooms rather than warehouse-scale farms.

What We Do Today

We visit equipment rooms across the Seoul metropolitan area — basement conversions, corridor cabinets, and small co-location bays — and publish field notes on hash-rate thresholds, cooling, and power delivery. Our flagship Rack Deployment Review remains the core service; thermal audits and circuit mapping support operators who already have hardware running or need a narrower scope.

Team

Ji-won Han — Lead assessor. Former facilities technician for a Gangnam data corridor. Handles on-site measurement and report authoring.

Sora Kim — Thermal analyst. Background in HVAC commissioning. Runs heat mapping and shelf spacing recommendations.

Dae-hyun Lee — Electrical reviewer. Licensed electrician (non-practising). Reviews panel schedules and circuit mapping deliverables.

Working Approach

We do not sell miners, accept referral fees from manufacturers, or operate mining pools. Assessments are paid engagements with disclosed scope. Reports name specific models, measurements, and constraints — not generic checklists.

Values

Measure first. Rail depth and breaker headroom are numbers, not guesses.

Write it down. Every visit produces a report the operator can hand to an electrician or co-location manager.

Stay in the room. Our expertise is dense equipment rooms in urban South Korea, not open-field farm design.

Community

We contribute field notes to local operator groups in Songpa-gu and publish guides for rooms where 0.05 TH/s units are the practical minimum for rack density without overspending on power infrastructure.
