Based on your goals you need roughly 4 CPU threads, 20GB RAM and 32TB of storage. This system runs 24/7, so energy matters. Recommended: the Smart build — best all-round — 1417€ purchase, ~30W idle, ~116€/year energy (≈347€ over 3 years). Intel Core i3 14100: 8 threads covers the 4 needed with headroom. Motherboard Intel Z790 (LGA 1700): matches the CPU socket and case size. RAM: 32GB DDR4 — meets the 20GB the workload requires. Chose Intel Core i3 14100 over Intel Core i3 14100F: better overall fit for your priorities. Build DNA: performance 100, value 84, efficiency 77, expandability 100, silence 95, longevity 100 — overall 93/100. Heads-up: Total (1417€) exceeds your budget (700€) by 717€ (102%). Ranking already prefers in-budget variants — this one is shown for comparison; check the value variant or raise the budget. What limits you first: storage. Alternatives: Value build — most for your money — 1417€, DNA 88/100, balanced · Long-term build — expandable & future-proof — 1428€, DNA 93/100, balanced.

Wir teilen deinen Build in die Leistung auf, die du brauchst, die Leistung, die du kaufst, und die Leistung, die du wahrscheinlich täglich nutzt. Wenn die Lücke groß ist, kaufst du zu viel.
BALANCED – der Build ist nahe an dem dimensioniert, was die Workload erfordert.

Was das bedeutet
Ein erklärbarer Zukunftssicherheits-Score, der Homelab-Risiko-Score, ein finaler Vor-Kauf-Audit und was im Laufe der Zeit zum limitierenden Faktor wird.
Starke Zukunftssicherheit
Strong future-proofing (79/100) — this build should stay relevant for years without major surgery.
DIY build — the CPU, motherboard and PSU can each be upgraded independently without replacing the whole system.
Expansion headroom: 2 PCIe slot(s), 2 M.2, 3 SATA, 1 drive bay(s), 2 RAM slot(s) free.
Storage is 80% utilized with 1 free drive bay(s) and 3 free SATA port(s).
2 RAM slot(s) free; memory is 63% utilized.
Networking is 2500 Mbps, and a free PCIe slot can add a faster NIC later.
ATX form factor with standard, socketed components — most parts are easy to replace.
No GPU, but there is room (2 PCIe slot(s), PSU headroom 6.8x) to add one for AI/transcoding.
Geringes Risiko
Low risk (13/100) — sensible redundancy and headroom; no single point of failure is exposed.
Single point of failure
Risiko: lowStorage has redundancy (mirror) — a single drive failure does not take the array down.
Lösung: Continue a 3-2-1 backup strategy; redundancy is not a backup.
Storage risk
Risiko: medium1 desktop hard drive(s) — not rated for 24/7 duty, vibration or heat; higher long-run failure risk.
Lösung: For an always-on system, prefer NAS/CMR-rated drives; monitor SMART and replace before the warranty ends.
Data loss risk
Risiko: lowRedundancy protects against drive failure, though it is not a substitute for backups.
Lösung: Follow a 3-2-1 backup rule: at least one copy off the box.
Power risk
Risiko: lowPSU is 650W, peak load 95W (15%).
Lösung: PSU sizing leaves healthy headroom for spikes and future parts.
Network risk
Risiko: lowSingle 2500 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 2500 Mbps.
Lösung: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.
Expansion risk
Risiko: low2 PCIe, 2 M.2, 3 SATA, 1 bays free.
Lösung: Healthy room for future drives, NICs and accelerators.
Upgrade risk
Risiko: low2024 platform — current generation with a forward-looking socket/feature set.
Lösung: Buy for the workload, not the socket — upgrade paths are a bonus, not a guarantee.
Audit found 1 critical and 0 warning item(s) worth fixing before you buy.
Check the balance
KritischTotal (1417€) exceeds your budget (700€) by 717€ (102%). Ranking already prefers in-budget variants — this one is shown for comparison; check the value variant or raise the budget.
Aktion: Reconsider the config for the stated workload or budget before buying.
Kategorie: balance
Use NAS-rated drives
OptimierungDesktop drives in an always-on NAS/server role have higher long-run failure rates.
Aktion: Prefer NAS/CMR-rated drives for 24/7 duty.
Kategorie: storage
Add a UPS
OptionalAn always-on server holding data should survive power blips.
Aktion: Add an online/line-interactive UPS sized to the build's idle draw.
Kategorie: power
Keep a backup off-box
OptionalRedundancy inside the box does not survive fire, theft or a whole-array fault.
Aktion: Mirror the important data to an external drive, a second box, or cloud.
Kategorie: storage
RAM expansion available
Zukunft2 RAM slot(s) free for a later upgrade.
Aktion: Leave them free until the workload actually grows.
Kategorie: memory
Drive bays remain
Zukunft1 drive bay(s) free for future capacity.
Aktion: Expand capacity in pairs (mirror/parity) when needed.
Kategorie: storage
PCIe slot available
Zukunft2 free PCIe slot(s) for a NIC, HBA or GPU later.
Aktion: Use it for a 10G NIC, extra HBA, or an accelerator when the need appears.
Kategorie: expansion
Storage nearly full is the most likely thing to date this build within 1-2y.
Storage nearly full
Warum: 80% of raw capacity is already in use — media libraries and backups grow fast.
Was zu tun ist: Expanding is easy: add a drive to the free bays/ports.
storage is the closest to its limit (80% of capacity in use) — it will likely force the next upgrade.
