Future-proof score

Strong future-proofing

83/100

Strong future-proofing (83/100) — this build should stay relevant for years without major surgery.

Upgrade path75

DIY build — the CPU, motherboard and PSU can each be upgraded independently without replacing the whole system.

Expansion100

Expansion headroom: 3 PCIe slot(s), 1 M.2, 4 SATA, 2 drive bay(s), 2 RAM slot(s) free.

Storage growth90

Storage is 45% utilized with 2 free drive bay(s) and 4 free SATA port(s).

Memory growth75

2 RAM slot(s) free; memory is 100% utilized.

Networking80

Networking is 2500 Mbps, and a free PCIe slot can add a faster NIC later.

Replacement ease90

ATX form factor with standard, socketed components — most parts are easy to replace.

Workload change70

No GPU, but there is room (3 PCIe slot(s), PSU headroom 4.8x) to add one for AI/transcoding.

Homelab Risk Score

Moderate risk

37/100

Moderate risk (37/100) — a few items are worth fixing before you commit (see checklist).

critical

Single point of failure

All data sits on a single drive with no redundancy — one failure means total loss.Fix: Add at least a mirror (RAID 1/ZFS mirror) for irreplaceable data, or an additional parity drive for larger arrays.

low

Storage risk

Solid-state storage — no moving parts, low mechanical failure risk.Fix: For an always-on system, prefer NAS/CMR-rated drives; monitor SMART and replace before the warranty ends.

high

Data loss risk

1 drive(s) with no redundancy — a single SSD/controller failure can still lose data.Fix: Add redundancy and an off-site/off-box backup for anything irreplaceable.

low

Power risk

PSU is 500W, peak load 104W (21%).Fix: PSU sizing leaves healthy headroom for spikes and future parts.

low

Network risk

Single 2500 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 2500 Mbps.Fix: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.

low

Expansion risk

3 PCIe, 1 M.2, 4 SATA, 2 bays free.Fix: Healthy room for future drives, NICs and accelerators.

low

Upgrade risk

2025 platform — current generation with a forward-looking socket/feature set.Fix: Buy for the workload, not the socket — upgrade paths are a bonus, not a guarantee.

Final build audit

Audit found 4 critical and 0 warning item(s) worth fixing before you buy.

4 Critical1 Optional3 Future

Critical

Check the balance

Requested maxNoise=quiet but case Lian Li SUP01 ATX Mid Tower White Tempered Glass Side Panel is "standard" — silent option unavailable, falling back.Action: Reconsider the config for the stated workload or budget before buying.balance

Critical

Check the balance

This build may struggle with the stated workload.Action: Reconsider the config for the stated workload or budget before buying.balance

Critical

No storage redundancy

1 drive(s) with no mirror or parity for the data you plan to store.Action: Add at least a mirror for irreplaceable data before you migrate anything.storage

Critical

RAM is nearly exhausted

The workload needs 100% of available RAM — swapping will hurt.Action: Add more RAM now, while slots are still free.memory

Optional

Keep a backup off-box

Redundancy inside the box does not survive fire, theft or a whole-array fault.Action: Mirror the important data to an external drive, a second box, or cloud.storage

Future

RAM expansion available

2 RAM slot(s) free for a later upgrade.Action: Leave them free until the workload actually grows.memory

Future

Drive bays remain

2 drive bay(s) free for future capacity.Action: Expand capacity in pairs (mirror/parity) when needed.storage

Future

PCIe slot available

3 free PCIe slot(s) for a NIC, HBA or GPU later.Action: Use it for a 10G NIC, extra HBA, or an accelerator when the need appears.expansion

What becomes the limit

RAM is tight is the most likely thing to date this build within 1-2y.

1-2y

RAM is tight

Why: Memory is 100% utilized — a growing workload will hit the ceiling quickly.What to do: Add the remaining RAM before prices change, while slots are free.
