The PERFECT Mini Home Server

Summary

Tiny “mini micro” business PCs (HP/Lenovo/Dell) for homelabs

• These small OEM office PCs are popular in the used market (especially for homelabs) because they offer:
  • solid performance
  • small footprint
  • low cost (often under ~$50 for older models)
• Newer generations cost more (often ~2x), but the argument is that efficiency/performance isn’t automatically ~2x better.
• The real upgrade value is often about new features, especially:
  • I/O flexibility
  • enterprise options for tinkering

VPN self-hosting vs using a commercial VPN (sponsor)

• The video recommends Private Internet Access (PIA) as an option.
• Mentioned VPN features:
  • fast speeds
  • many global servers
  • multi-device support
  • Linux support
  • use with Docker (example: routing other containers via a VPN container named “Gluten”)
  • port forwarding
  • split tunneling
  • strict audited no-logs policy (third-party audited)

Hardware review: HP ProDesk 600 G6 Mini (and related models)

Purchase/deal context

• The speaker buys an HP ProDesk 600 G6 Mini (Gen 6) via auction for about $150 + shipping.
• Notes that buying immediately can be much higher.
• They had to buy an AC adapter separately (it wasn’t included).
• Opening the case is described as straightforward:
  • single rear screw to access internals
  • remove the fan to access RAM
  • three screws for the CPU heatsink

Key specs (ProDesk 600 G6 Mini)

• CPU: Intel i5-10500T (6-core, hyperthreaded)
  • Base: 2.3 GHz
  • Turbo: up to 3.8 GHz
• GPU: Intel UHD 630
• Memory: up to 128 GB DDR4 2666, shipped with 16 GB
• Storage / expansion:
  • two NVMe M.2 sockets, PCIe Gen 3 x4
  • one M.2 “E key” slot for Wi‑Fi
    • supports 1 lane PCIe Gen 3

I/O highlights

• Front:
  • two high-speed USB ports (one USB-C)
  • another USB-A port (rated 5 Gbit/s)
  • audio jack, power button
• Back:
  • dual DisplayPort 1.4
  • multiple high-speed USB ports
  • gigabit Ethernet
  • 19V DC barrel power
• Flex IO (major selling point):
  • A special Flex IO port supports swappable modules (e.g., HDMI adapters, Thunderbolt, network modules, etc.).
  • The video emphasizes Flex IO as a key reason to buy newer G6 systems.

Comparison systems: HP EliteDesk G3 Mini and HP Engage Flex Mini (POS-focused)

HP Engage Flex Mini (POS/hospitality variant)

• Similar form factor to ProDesk.
• Differences found:
  • no product name on the front
  • no Wi‑Fi adapter included
  • slight motherboard revision differences (VRM placement)
  • a damaged CMOS battery handled with a super-glued 3D-printed part
• Specs mentioned:
  • i3-10100T
  • 8 GB RAM
  • (vs the G6 unit’s i5-10500T + 16 GB)

HP EliteDesk vs ProDesk vs Engage

• The speaker suggests Elite Desk (non-GPU variants) are broadly similar to ProDesk but may include:
  • higher-end CPU options
  • potentially more power phases / better thermals
  • some differing enterprise features (e.g., mentions a mesh lid)

Benchmarks & efficiency analysis (what improved and why)

Compute performance

• Benchmarked using Cinebench R23 and Geekbench 6:
  • newer system single-thread improvement is not huge over older models
  • multi-thread scaling generally favors higher-core-count systems
    • example: another older EliteDesk 800 G3 Mini with a 12-core i5 performs best in Cinebench multi-thread

Power draw

• Windows idle tests: newer systems often do slightly better, but differences are only a few watts.
• Proxmox idle: after power tuning scripts, one test slightly favors the older system.

Render efficiency (points per watt concept)

• During Cinebench rendering:
  • ProDesk eventually reaches ~51 W after an initial boost
  • Engage and ProDesk sustain higher power but score better
• Efficiency judged as:
  • score divided by watts (“points per watt”)
• Result:
  • N100 leads efficiency
  • the older EliteDesk lags efficiency vs newer units

Main homelab guides (G6 Flex IO focus)

1) Upgrading networking via Flex IO (recommended approach)

• Swap Flex IO networking modules.
• Best-recommended modules:
  • 2.5GbE or 10GbE adapters
• Example used:
  • an Intel i225V controller (not Realtek), which is considered favorable for pfSense / OPNsense
• Installation overview:
  • remove a few screws
  • swap the M.2/Flex module

2) Dual-NIC + Proxmox workflow

• After adding the Flex IO network interface:
  • Proxmox sees a second network interface
• The speaker tests/uses the machine with Proxmox as the homelab OS.

3) Repurposing the Wi‑Fi (E‑key) slot using adapters

• Used an E‑key to 2.5GbE adapter through the M.2 E slot.
• Notes on fabrication/safety:
  • clearance required trimming part of the lid
  • used Kapton tape for electrical safety
    • motivated by a prior incident where they shorted a system and had to replace hardware

4) NVMe boot storage expansion strategy

• Used an E‑key to M‑key adapter to mount an NVMe SSD:
  • SSD orientation adjusted by reversing fitment
• Since full-size NVMe (2280) was too large:
  • a portion of the adapter was snapped off
  • they used a smaller 2230 NVMe SSD instead
• Estimated result:
  • roughly ~1 GB/s boot performance (consistent with PCIe Gen3 x1 behavior)
  • while preserving the two primary NVMe slots for storage/mirroring/VMs

5) Attempted SATA/HDD enclosure approach (problematic)

• Tried chaining adapters:
  • M.2 to SATA
  • then SATA-to-(multi-drive ES&A style enclosure)
• Outcome:
  • drives detected initially
  • system became buggy and Proxmox crashed
• Likely cause:
  • misunderstanding enclosure protocol, possibly compounded by corrosion

6) Adding an extra 2.5” HDD option (discovered capability)

• Found a hidden connector that looks similar to an older SATA connector.
• Discovery:
  • G6 units can be configured with a 2.5” HDD
  • but these units lacked the necessary cage/adapter hardware
• Cost/effort note:
  • getting the full cable/cage assembly may cost more
  • suggested alternate approach: buy a SATA adapter from an earlier model and mount creatively

Remote management features (Intel AMT / Mesh Commander) and KVM behavior

Intel AMT platform for remote management

• These enterprise systems include Intel AMT, enabling management even when the machine is off.
• The speaker uses Mesh Commander to manage:
  • remote power on/off
  • serial over LAN
  • additional controls

KVM availability and troubleshooting

• Early on, they report ProDesk did not support KVM (based on their earlier test).
• Later, an Elite Desk arrived during editing:
  • they confirm KVM works on the Elite Desk.
• Serial console troubleshooting:
  • first attempt resulted in a blank screen
  • they then used OS tools (e.g., checking dmesg / Proxmox serial device)
  • modified grub config to enable a console service
• Final result:
  • console works but is sluggish
  • speaker frames it as a cost-effective alternative to buying a dedicated KVM

BIOS lock bypass (warning + method from external blog)

BIOS/password locked systems

• Older G3 EliteDesk could be cleared by shorting a jumper (easy method).
• G6 doesn’t have that jumper.

Reset method (from Reese Goodwin blog)

• Described procedure:
  1. On one of two flash chips: short specific pin(s) to ground
  2. attempt boot while the “scary LEDs” are on
  3. power cycle again
  4. lock cleared (speaker reports success)

Caution: “Do at your own risk.” No guarantee—could brick or damage hardware.

Key takeaways / recommendations

• The best reason to upgrade generations is not raw CPU performance; it’s I/O expansion, especially Flex IO in G6.
• For typical homelab workloads and virtualization:
  • these systems generally handle tasks well.
• For networking builds:
  • Flex IO + Intel NICs can make pfSense/OPNsense setups smoother.
• For enterprise remote management:
  • Intel AMT + Mesh Commander enables hands-off management; KVM support varies by model.
