Overall80

Future-proof score

Strong future-proofing

77/100

Strong future-proofing (77/100) — 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.

Expansion82

Expansion headroom: 3 PCIe slot(s), 1 M.2, 3 SATA, 0 drive bay(s), 2 RAM slot(s) free.

Storage growth70

Storage is 71% utilized with 0 free drive bay(s) and 3 free SATA port(s).

Memory growth75

2 RAM slot(s) free; memory is 75% utilized.

Networking80

Networking is 5000 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 (the iGPU handles transcoding), but there is room (3 PCIe slot(s), PSU headroom 3.8x) to add one for AI.

Homelab Risk Score

Moderate risk

37/100

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

high

Single point of failure

Storage has no redundancy (3 drives, no mirror/parity) — a single drive failure exposes the array.Fix: Add at least a mirror (RAID 1/ZFS mirror) for irreplaceable data, or an additional parity drive for larger arrays.

low

Storage risk

1 NAS-rated hard drive(s) — rated for 24/7 operation.Fix: Keep drives cool and monitor SMART health.

critical

Data loss risk

3 drive(s), no redundancy, hard-drive media — the worst combination for keeping data safe.Fix: Add redundancy and an off-site/off-box backup for anything irreplaceable.

low

Power risk

PSU is 400W, peak load 105W (26%).Fix: PSU sizing leaves healthy headroom for spikes and future parts.

low

Network risk

Single 5000 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 5000 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, 3 SATA, 0 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 0 critical and 2 warning item(s) worth fixing before you buy.

2 Warning2 Optional2 Future

Warning

Review

System idles ~32W vs maxIdlePowerW=30W requested (CPU ~7W + drives/fans). Closest efficient option shown — lower the workload or raise the cap for full compliance.Action: Weigh this trade-off against your priorities.balance

Warning

No storage redundancy

3 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

Optional

Add a UPS

An always-on server holding data should survive power blips.Action: Add a line-interactive UPS sized for the build's peak draw (≥ 10 min at typical load for a clean shutdown).power

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

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

Most likely to date this build within 3-5y: Storage growing.

3-5y

Storage growing

Why: 71% of capacity in use — comfortable today, tighter over a few years.What to do: Plan the growth curve; keep at least one bay free for the next drive.
