Acoustic & Thermal Ducting Engineering

The HP ProDesk 400 G5 Desktop Mini employs a customized low-profile centrifugal blower fan assembly paired with a copper heatpipe radiator. Ambient intake air is pulled through the front perforated bezel, passes directly across the dual DDR4 SODIMM banks and M.2 NVMe SSD, and exhausts horizontally through the rear cooling fins. The 35W low-power profile of the Core i3-9100T keeps fan speeds at minimum RPM under sustained hypervisor workloads.

9. Operating System & Virtualization Roles

Virtualization & Workload Roles

  • Authoritative Immich Host: Hosts production Immich VM 102 with dedicated containerized AI photo indexing, embedding, and facial recognition pipelines.
  • Standalone Hypervisor: Proxmox VE 9.2.11 cluster node with independent storage thin pool (pve/data approx. 348.8 GiB).
  • Mesh Transport: Pinpoint Tailscale endpoint (100.83.60.31) providing encrypted inter-site management and zero-trust administrative access.

Rollback Evidence & Integrity

  • Protected SATA SSD: Verbatim Vi560 S3 SSD preserves an unmounted, intact Windows 10 Pro environment for instant hardware diagnostics and firmware provisioning.
  • Local Host Rollback: Pre-change configuration manifest verified at /root/cz-brn-neu-onboarding-rollback-20260822T193922+0200/ (12/12 verified files).
  • SMART & Telemetry Health: Zero pending sectors, zero UDMA CRC errors, and 100% spare reserve across all solid-state media.

10. Diagnostic Health & Operational Assessment

  1. Processor & Hypervisor Efficiency: The installed Intel Core i3-9100T (S-Spec SRCZX, B0 stepping • Exhibit #2877) delivers dependable quad-core compute within a low 35W thermal envelope, providing an ideal, whisper-quiet platform for the standalone Proxmox node i3.
  2. High-Density 64 GB Memory Infrastructure: Configured with 64.0 GB of Corsair Vengeance DDR4 memory across dual SODIMM slots running at 2400 MT/s, providing substantial headroom for Linux ZFS caching and dense VM memory allocations.
  3. Storage Subsystem Integrity: Primary Kingston 512 GB NVMe SSD operates at 35°C with 0 media errors and 100% available spare, hosting the 348.8 GiB LVM-thin guest store. The secondary Verbatim Vi560 SSD safely preserves the offline Windows installation without Proxmox interference.
  4. Network & Edge Reliability: Gigabit Realtek LAN functions at 1000 Mb/s full-duplex with active IOMMU group 11 isolation, while encrypted Tailscale mesh connectivity provides seamless administrative reachability across the CZ-BRN-NEU homelab topology.
