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.

diy · tower build on LGA 1700 + Intel Z790
Nous répartissons ton build entre la performance dont tu as besoin, celle que tu achètes et celle que tu utiliseras probablement au quotidien. Quand l'écart est grand, tu achètes trop.
BALANCED — le build est dimensionné au plus près des exigences de la charge.

Ce que cela signifie
Un score de pérennité explicable, le score de risque homelab, un audit final avant achat et ce qui deviendra le facteur limitant au fil du temps.
Pérennité solide
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.
Risque faible
Low risk (13/100) — sensible redundancy and headroom; no single point of failure is exposed.
Single point of failure
Risque: lowStorage has redundancy (mirror) — a single drive failure does not take the array down.
Solution: Continue a 3-2-1 backup strategy; redundancy is not a backup.
Storage risk
Risque: medium1 desktop hard drive(s) — not rated for 24/7 duty, vibration or heat; higher long-run failure risk.
Solution: For an always-on system, prefer NAS/CMR-rated drives; monitor SMART and replace before the warranty ends.
Data loss risk
Risque: lowRedundancy protects against drive failure, though it is not a substitute for backups.
Solution: Follow a 3-2-1 backup rule: at least one copy off the box.
Power risk
Risque: lowPSU is 650W, peak load 95W (15%).
Solution: PSU sizing leaves healthy headroom for spikes and future parts.
Network risk
Risque: lowSingle 2500 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 2500 Mbps.
Solution: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.
Expansion risk
Risque: low2 PCIe, 2 M.2, 3 SATA, 1 bays free.
Solution: Healthy room for future drives, NICs and accelerators.
Upgrade risk
Risque: low2024 platform — current generation with a forward-looking socket/feature set.
Solution: 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
CritiqueTotal (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.
Action: Reconsider the config for the stated workload or budget before buying.
Catégorie: balance
Use NAS-rated drives
OptimisationDesktop drives in an always-on NAS/server role have higher long-run failure rates.
Action: Prefer NAS/CMR-rated drives for 24/7 duty.
Catégorie: storage
Add a UPS
OptionnelAn always-on server holding data should survive power blips.
Action: Add an online/line-interactive UPS sized to the build's idle draw.
Catégorie: power
Keep a backup off-box
OptionnelRedundancy 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.
Catégorie: storage
RAM expansion available
Futur2 RAM slot(s) free for a later upgrade.
Action: Leave them free until the workload actually grows.
Catégorie: memory
Drive bays remain
Futur1 drive bay(s) free for future capacity.
Action: Expand capacity in pairs (mirror/parity) when needed.
Catégorie: storage
PCIe slot available
Futur2 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.
Catégorie: expansion
Storage nearly full is the most likely thing to date this build within 1-2y.
Storage nearly full
Pourquoi: 80% of raw capacity is already in use — media libraries and backups grow fast.
Que faire: 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.
