Based on your goals you need roughly 12 CPU threads, 48GB RAM and 2TB of storage with ai GPU capability. This system runs 24/7, so energy matters. Recommended: the Value build — most for your money — 7587€ purchase, ~98W idle, ~680€/year energy (≈2039€ over 3 years). Intel Core i5 14400F: 16 threads covers the 12 needed with headroom. Motherboard Intel Z790 (LGA 1700): matches the CPU socket and case size. RAM: 64GB DDR4 — meets the 48GB the workload requires. NVIDIA RTX PRO 6000 Blackwell Workstation Edition 96GB GDDR7: 96GB VRAM selected for your ai GPU need. Chose Intel Core i5 14400F over AMD Ryzen 5 5600T OEM/Tray: better overall fit for your priorities. Build DNA: performance 89, value 0, efficiency 16, expandability 100, silence 95, longevity 100 — overall 38/100. Heads-up: Total (7587€) exceeds your budget (4500€) by 3087€ (69%). Ranking already prefers in-budget variants — this one is shown for comparison; check the value variant or raise the budget. What limits you first: RAM. Alternatives: Smart build — best all-round — 8109€, DNA 79/100, balanced · Long-term build — expandable & future-proof — 7790€, DNA 80/100, balanced · Performance build — maximum capability — 8109€, DNA 78/100, balanced.

O que significa
Uma pontuação de prova de futuro explicável, o Homelab Risk Score, uma auditoria final antes de comprar e o que se tornará o fator limitante ao longo do tempo.
Prova de futuro forte
Strong future-proofing (84/100) — 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), 2 M.2, 4 SATA, 2 drive bay(s), 2 RAM slot(s) free.
Storage is 25% utilized with 2 free drive bay(s) and 4 free SATA port(s).
2 RAM slot(s) free; memory is 75% 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.
A 96GB GPU is present — AI and transcoding workloads are covered.
Risco moderado
Moderate risk (37/100) — a few items are worth fixing before you commit (see checklist).
Single point of failure
Risco: criticalAll data sits on a single drive with no redundancy — one failure means total loss.
Solução: Add at least a mirror (RAID 1/ZFS mirror) for irreplaceable data, or an additional parity drive for larger arrays.
Storage risk
Risco: lowSolid-state storage — no moving parts, low mechanical failure risk.
Solução: For an always-on system, prefer NAS/CMR-rated drives; monitor SMART and replace before the warranty ends.
Data loss risk
Risco: high1 drive(s) with no redundancy — a single SSD/controller failure can still lose data.
Solução: Add redundancy and an off-site/off-box backup for anything irreplaceable.
Power risk
Risco: lowPSU is 1000W, peak load 704W (70%).
Solução: PSU sizing leaves healthy headroom for spikes and future parts.
Network risk
Risco: lowSingle 2500 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 2500 Mbps.
Solução: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.
Expansion risk
Risco: low1 PCIe, 2 M.2, 4 SATA, 2 bays free.
Solução: Healthy room for future drives, NICs and accelerators.
Upgrade risk
Risco: low2024 platform — current generation with a forward-looking socket/feature set.
Solução: Buy for the workload, not the socket — upgrade paths are a bonus, not a guarantee.
Audit found 2 critical and 0 warning item(s) worth fixing before you buy.
Check the balance
CríticoTotal (7587€) exceeds your budget (4500€) by 3087€ (69%). Ranking already prefers in-budget variants — this one is shown for comparison; check the value variant or raise the budget.
Ação: Reconsider the config for the stated workload or budget before buying.
Categoria: balance
No storage redundancy
Crítico1 drive(s) with no mirror or parity for the data you plan to store.
Ação: Add at least a mirror for irreplaceable data before you migrate anything.
Categoria: storage
Keep a backup off-box
OpcionalRedundancy inside the box does not survive fire, theft or a whole-array fault.
Ação: Mirror the important data to an external drive, a second box, or cloud.
Categoria: storage
RAM expansion available
Futuro2 RAM slot(s) free for a later upgrade.
Ação: Leave them free until the workload actually grows.
Categoria: memory
Drive bays remain
Futuro2 drive bay(s) free for future capacity.
Ação: Expand capacity in pairs (mirror/parity) when needed.
Categoria: storage
PCIe slot available
Futuro1 free PCIe slot(s) for a NIC, HBA or GPU later.
Ação: Use it for a 10G NIC, extra HBA, or an accelerator when the need appears.
Categoria: expansion
Nothing obvious becomes a limiting factor in the near term — this build should age well.
RAM is the closest to its limit (75% of capacity in use) — it will likely force the next upgrade.
