Based on your goals you need roughly 4 CPU threads, 16GB RAM and 2TB of storage. This system runs 24/7, so energy matters. Recommended: the Value build — most for your money — 454€ purchase, ~6W idle, ~25€/year energy (≈76€ over 3 years). GEEKOM Air12 — Intel Pentium Gold 7505: 4 threads, 8GB RAM, 5W idle — a complete, efficient prebuilt for this workload. Turnkey: no assembly, smaller footprint, lower energy than a custom build. Build DNA: performance 70, value 100, efficiency 99, expandability 10, silence 90, longevity 100 — overall 88/100. Heads-up: Total (454€) exceeds your budget (400€) by 54€ (14%). Ranking already prefers in-budget variants — this one is shown for comparison. This build may struggle with the workload. What limits you first: CPU. Alternatives: Smart build — best all-round — 537€, DNA 91/100, overkill · Long-term build — expandable & future-proof — 537€, DNA 86/100, overkill · Efficiency build — lowest energy — 537€, DNA 93/100, overkill · Silent build — acoustics first — 537€, DNA 89/100, overkill · Build yourself — for comparison — 883€, DNA 92/100, balanced.

prebuilt · mini system — Intel Pentium Gold 7505
We split your build into the performance you need, the performance you're buying, and the performance you're likely to use day-to-day. When the gap is wide, you're overbuying.
The build is tight on resources for the stated workload — it may struggle under load.

What this means
An explainable future-proof score, the Homelab Risk Score, a final pre-purchase audit and what will become the limiting factor over time.
Limited future-proofing
Limited future-proofing (34/100) — expect to upgrade or rebuild sooner rather than later.
Prebuilt platform — the CPU/motherboard are not swappable in the usual sense, so the upgrade path is limited to RAM/storage/PCIe.
Expansion headroom: 0 PCIe slot(s), 0 M.2, 0 SATA, 0 drive bay(s), 1 RAM slot(s) free.
Storage is 24% utilized with 0 free drive bay(s) and 0 free SATA port(s).
1 RAM slot(s) free; memory is 40% utilized.
Networking is 1000 Mbps.
Prebuilt — proprietary parts can make replacement harder.
No GPU and little room to add one — demanding AI/transcoding workloads would be out of reach.
Elevated risk
Elevated risk (57/100) — several items should be addressed before purchase.
Single point of failure
Risk: criticalAll 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.
Storage risk
Risk: lowSolid-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.
Data loss risk
Risk: high1 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.
Power risk
Risk: criticalNo PSU detected in the configuration.
Fix: Add a PSU sized at ~1.5x the peak load for efficiency headroom.
Network risk
Risk: mediumSingle 1000 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 1000 Mbps.
Fix: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.
Expansion risk
Risk: high0 PCIe, 0 M.2, 0 SATA, 0 bays free.
Fix: If you foresee adding drives, a NIC or a GPU, choose a case/board with more slots before buying.
Upgrade risk
Risk: lowPrebuilt platform — the next CPU generation will almost certainly require a new system.
Fix: Buy for the workload, not the socket — upgrade paths are a bonus, not a guarantee.
Audit found 4 critical and 0 warning item(s) worth fixing before you buy.
Check the balance
CriticalTotal (454€) exceeds your budget (400€) by 54€ (14%). Ranking already prefers in-budget variants — this one is shown for comparison.
Action: Reconsider the config for the stated workload or budget before buying.

CriticalThis build may struggle with the workload.
Action: Reconsider the config for the stated workload or budget before buying.
Category: balance
No storage redundancy
Critical1 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.
Category: storage
CPU close to the limit
CriticalThe workload uses 100% of the CPU — little headroom for background tasks or growth.
Action: Consider a stronger CPU or drop a secondary workload.
Category: compute
Plan faster networking
Optimization1G networking is fine today but will bottleneck multi-user media or big NAS transfers at 2TB.
Action: Budget for a 2.5G/10G NIC and switch later, or spec it now.
Category: network
Keep a backup off-box
OptionalRedundancy 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.
Category: storage
RAM expansion available
Future1 RAM slot(s) free for a later upgrade.
Action: Leave them free until the workload actually grows.
Category: memory
CPU is the next bottleneck is the most likely thing to date this build within 1-2y.
CPU is the next bottleneck
Why: The CPU runs at 100% of capacity — new services or more users will hit the wall first.
What to do: Plan a platform upgrade; the prebuilt CPU is not upgradable.
1G networking becomes the ceiling
Why: A 1000 Mbps link will cap NAS transfers and multi-user media before the CPU or disks do.
What to do: Factor a NIC into the next hardware purchase.
No expansion left
Why: Every slot and bay is used — adding anything means replacing parts.
What to do: Keep this build single-purpose and plan a second box for new workloads.
CPU is the closest to its limit (100% of capacity in use) — it will likely force the next upgrade.
