A mini PC cluster diagram keeps each small compute host visible. Shared NAS storage and the switch path stay clear. This embedded preview is rendered by the same ReactFlow HardwareNode, RackNode, and CustomEdge components used in HLBuilder's visual builder.

Draw each host separately

A cluster made from small PCs should not be drawn as one vague server. Each mini PC has its own network path, service load, and failure behavior. HLBuilder can show those hosts as separate nodes.

This helps when a user needs to move a workload. A service can shift from one mini PC to another without redrawing the whole lab.

Keep shared storage visible

A mini PC layout often depends on separate storage. Put the NAS or storage server on the same diagram, then connect it through the switch path. The storage node should not be hidden in text.

This matters for backups too. If all mini PCs depend on one NAS, the diagram should make that dependency obvious.

Avoid a flat host list

A flat list says there are three mini PCs. A topology says how they connect and which services they host. HLBuilder is useful because the canvas carries both the hardware role and the connection path.

When a cluster grows, add the next mini PC to the diagram before buying it. That checks switch ports, IP ranges, and storage needs in one place.

Builder checks

Check

Each mini PC appears as its own node.

Check

Shared storage appears as a NAS or storage server node.

Check

Service groups are labeled per host.

Check

Switch capacity is visible before another node is added.

Common questions

Is a mini PC cluster good for a first homelab?

It can be, if the user wants several small hosts and understands the extra cabling, power, and management work.

What does HLBuilder add to a mini PC cluster plan?

It shows each host, the switch path, shared storage, and service placement on the same canvas.
