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 — 1033€ purchase, ~56W idle, ~231€/year energy (≈694€ over 3 years). Intel Core i7 7820X: 16 threads covers the 8 needed with headroom. Motherboard Intel X299 (LGA 2066): matches the CPU socket and case size. RAM: 128GB DDR4 — meets the 62GB the workload requires. Chose Intel Core i7 7820X over AMD Ryzen 7 7700X3D: better overall fit for your priorities. Build DNA: performance 100, value 91, efficiency 54, expandability 100, silence 95, longevity 100 — overall 94/100. Heads-up: Requested 2500 Mbps but board Intel X299 has max 1000 Mbps onboard and no free PCIe slot — staying on onboard networking. Add a board with a free slot for 2.5G/10G. What limits you first: CPU. Alternatives: Value build — most for your money — 744€, DNA 91/100, tight_on_resources · Long-term build — expandable & future-proof — 1033€, DNA 94/100, balanced.

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 (71/100) — 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: 1 PCIe slot(s), 3 M.2, 8 SATA, 2 drive bay(s), 0 RAM slot(s) free.
Storage is 50% utilized with 2 free drive bay(s) and 8 free SATA port(s).
0 RAM slot(s) free; memory is 49% utilized.
Networking is 1000 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 (1 PCIe slot(s), PSU headroom 3.3x) to add one for AI/transcoding.
Risque modéré
Moderate risk (46/100) — 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 650W, peak load 198W (30%).
Solution: PSU sizing leaves healthy headroom for spikes and future parts.
Network risk
Risque: criticalThe workload wants 2500 Mbps but the config only provides 1000 Mbps.
Solution: Add a 2.5G NIC or upgrade the platform.
Expansion risk
Risque: low1 PCIe, 3 M.2, 8 SATA, 2 bays free.
Solution: Healthy room for future drives, NICs and accelerators.
Upgrade risk
Risque: low20117 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 1 warning item(s) worth fixing before you buy.

Review
AvertissementRequested 2500 Mbps but board Intel X299 has max 1000 Mbps onboard and no free PCIe slot — staying on onboard networking. Add a board with a free slot for 2.5G/10G.
Action: Weigh this trade-off against your priorities.
Catégorie: balance
Plan faster networking
Optimisation1G networking is fine today but will bottleneck multi-user media or big NAS transfers at 4TB.
Action: Budget for a 2.5G/10G NIC and switch later, or spec it now.
Catégorie: network
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
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
Futur1 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.
1G networking becomes the ceiling
Pourquoi: A 1000 Mbps link will cap NAS transfers and multi-user media before the CPU or disks do.
Que faire: Add a 2.5G/10G NIC when the switch investment makes sense.
CPU is the closest to its limit (50% of capacity in use) — it will likely force the next upgrade.
