No storage redundancy
Critique1 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.

Based on your goals you need roughly 8 CPU threads, 62GB RAM and 4TB of storage. This system runs 24/7, so energy matters. Recommended: the Smart build — best all-round — 1300€ purchase, ~51W idle, ~259€/year energy (≈778€ over 3 years). AMD Ryzen 7 7700X3D: 16 threads covers the 8 needed with headroom. Motherboard AMD B850 (AM5): matches the CPU socket and case size. RAM: 96GB DDR5 — meets the 62GB the workload requires. Chose AMD Ryzen 7 7700X3D over Intel Core Ultra 5 250K Plus: better overall fit for your priorities. Build DNA: performance 100, value 86, efficiency 58, expandability 100, silence 95, longevity 100 — overall 94/100. What limits you first: RAM. Alternatives: Value build — most for your money — 654€, DNA 91/100, tight_on_resources · Long-term build — expandable & future-proof — 1300€, DNA 94/100, balanced.

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 (83/100) — 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), 3 M.2, 4 SATA, 2 drive bay(s), 2 RAM slot(s) free.
Storage is 50% utilized with 2 free drive bay(s) and 4 free SATA port(s).
2 RAM slot(s) free; memory is 65% 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 5.9x) to add one for AI/transcoding.
Risque modéré
Moderate risk (37/100) — a few items are worth fixing before you commit (see checklist).
Single point of failure
Risque: criticalAll data sits on a single drive with no redundancy — one failure means total loss.
Solution: Add at least a mirror (RAID 1/ZFS mirror) for irreplaceable data, or an additional parity drive for larger arrays.
Storage risk
Risque: lowSolid-state storage — no moving parts, low mechanical 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: high1 drive(s) with no redundancy — a single SSD/controller failure can still lose data.
Solution: Add redundancy and an off-site/off-box backup for anything irreplaceable.
Power risk
Risque: lowPSU is 1000W, peak load 169W (17%).
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, 3 M.2, 4 SATA, 2 bays free.
Solution: Healthy room for future drives, NICs and accelerators.
Upgrade risk
Risque: low2026 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.
No storage redundancy
Critique1 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.
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
Futur2 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 growing is the most likely thing to date this build within 3-5y.
Storage growing
Pourquoi: 50% of capacity in use — comfortable today, tighter over a few years.
Que faire: Plan the growth curve; keep at least one bay free for the next drive.
RAM is the closest to its limit (65% of capacity in use) — it will likely force the next upgrade.
