A quiet N150 mini PC running Proxmox VE, a small 2.5G unmanaged switch, and a USB DAS for bulk disks is the finished result this kit targets. Management stays on one NIC, VM or storage traffic can use the other, and the first big volume path is a TerraMaster D4-320 instead of stuffing media onto the tiny internal SSD.

This method is a hypervisor lab BOM, not an appliance NAS cart. For a Mac mini Plex host with a compact UPS, use Mac mini M4 Plex Server Kit with a Compact UPS. For a quiet under-desk NAS plus backup path, use Quiet Under-Desk NAS Kit for Plex and Backups. For host shortlists and dual-NIC context, see Best Mini PCs for a Home Server in 2026 and Beelink Mini S13 Mini PC Review. Who it is for: first Proxmox installs that want dual 2.5GbE, a matching multi-gig switch, and host-managed DAS storage without buying a full Synology or QNAP chassis on day one.

What You Need

This is one compatible hypervisor starter kit, not a mix-and-match catalog. Every core item is a live Amazon US listing already used on the site. Bring 2 to 4 SATA drives for the DAS if you want a meaningful pool; the BOM prices the enclosure plus one concrete 4TB Red Plus so you can scale in text.

Host (Proxmox VE)

Quiet Twin Lake N150 mini PC with dual 2.5GbE, SODIMM RAM, and dual M.2. Dual LAN is the Proxmox reason to pick the EQ14 over a compact single-NIC S13: one port for management, one for a VM bridge or storage VLAN later. Keep the internal SSD for Proxmox and guests, not the media library.

2.5G unmanaged switch

An 8-port multi-gig unmanaged switch so both EQ14 NICs and a future NAS or desktop can negotiate 2.5G without rewriting Cat5e closet runs. Unmanaged is intentional for a first lab: plug in, confirm link LEDs, and leave VLANs for a later managed upgrade. For desk-side 2.5G context, see Run 2.5GbE to the Desk: Everything You Need.

USB DAS storage

Four-bay USB 3.2 Gen 2 enclosure (diskless) as the first bulk volume path. Pass the enclosure through to a VM later, or bind-mount host paths into LXC. No hardware RAID in the box: arrays live in Proxmox, ZFS, or the guest. Compare enclosure options at Best DAS and USB RAID Enclosures in 2026.

First CMR drive (scale the bay count)

One concrete WD Red Plus 4TB CMR SKU to start. A useful DAS usually wants 2 to 4 matched drives; price the kit as enclosure plus one drive, then multiply. Leave infant-mortality SMART checks for day-one burn-in before you trust a mirror.

Ethernet

Cat 6 five-pack for host-to-switch, switch-to-router, and spares. Short 10 ft runs are enough for a desk or shelf lab. Do not run the Proxmox host on Wi-Fi for management or storage traffic.

Optional compact sine UPS

If the lab is always-on, the CP850PFCLCD pure sine UPS is the compact desk protector this method calls out. Size it for a clean shutdown of the mini PC plus switch, not for hours of battery movie night. Skip it only if the host already sits on a larger UPS elsewhere.

What It Costs

About $705 as of writing for the core kit (EQ14 + TL-SG108-M2 + D4-320 + one WD Red Plus 4TB + Cat 6 five-pack). Add about $140 if you include the CP850PFCLCD. Budget roughly another $100 to $300 when you fill the remaining DAS bays with matching CMR drives. Skip a second mini PC and a hardware RAID DAS until guests and backups prove the layout.

Step-by-Step Setup

  1. Download the current Proxmox VE ISO from the official project site, flash it to a USB stick with a known-good imager, and boot the Beelink EQ14 from that stick (use a wired keyboard and a temporary HDMI display for install).
  2. Install Proxmox to the internal SSD. Use a static management IP or DHCP reservation on the first 2.5G NIC. Finish the installer, reboot, then apply updates from the web UI or apt before creating guests.
  3. Connect both EQ14 NICs to the TL-SG108-M2 with Cat 6. Keep vmbr0 on the management NIC; add a second Linux bridge later when a guest needs the other uplink.
  4. Seat at least one WD Red Plus 4TB in the TerraMaster D4-320, attach the enclosure to a USB 3.2 Gen 2 port on the host (not a USB 2 hub), and confirm the disks appear under Proxmox Disks. Create a directory storage, LVM, or ZFS pool on the host, or PCI/USB-pass the enclosure to a storage VM when that is the plan.
  5. Create a first test VM or LXC, confirm outbound network on the management bridge, and only then migrate real services. Optional: plug the EQ14 adapter and the switch PSU into battery-backed outlets on the CyberPower CP850PFCLCD and enable USB shutdown signaling (NUT or vendor tools) so Proxmox can halt cleanly on low battery.
  6. Document the management URL, root credentials in a password manager, and which NIC is which. Smoke-test a guest reboot and a brief UPS pull if the CP850 is in the cart.

Mistakes to Avoid

Bottom line

For a first Proxmox home lab that is not a Mac mini Plex appliance and not a turnkey NAS, the EQ14 dual-2.5G host, TL-SG108-M2, TerraMaster D4-320 with CMR drives, and Cat 6 is the complete starter BOM. Add the CP850 when the box is always-on. Use Turn a Mac Mini M4 Into a Tiny Home Server: The Complete Build Guide when the goal is a Mac mini software stack instead of a hypervisor lab.
