Based on your goals you need roughly 12 CPU threads, 56GB RAM and 3TB of storage with ai GPU capability. This system runs 24/7, so energy matters. Recommended: the Value build — most for your money — 1372€ purchase, ~51W idle, ~221€/year energy (≈664€ 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: 128GB DDR4 — meets the 56GB the workload requires. Lenovo RTX A2000 Black 12GB GDDR6: 12GB 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 83, value 85, efficiency 58, expandability 100, silence 95, longevity 100 — overall 85/100. Heads-up: Total (1372€) exceeds your budget (1100€) by 272€ (25%). Ranking already prefers in-budget variants — this one is shown for comparison; check the value variant or raise the budget. What limits you first: CPU. Alternatives: Smart build — best all-round — 3032€, DNA 84/100, balanced · Long-term build — expandable & future-proof — 3319€, DNA 88/100, balanced.

Qué significa
Una puntuación de solidez futura explicable, el Homelab Risk Score, una auditoría final antes de comprar y qué se convertirá en el factor limitante con el tiempo.
Solidez futura sólida
Strong future-proofing (74/100) — 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), 0 RAM slot(s) free.
Storage is 38% utilized with 2 free drive bay(s) and 4 free SATA port(s).
0 RAM slot(s) free; memory is 44% 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 12GB GPU is present — AI and transcoding workloads are covered.
Riesgo moderado
Moderate risk (37/100) — a few items are worth fixing before you commit (see checklist).
Single point of failure
Riesgo: criticalAll data sits on a single drive with no redundancy — one failure means total loss.
Solución: Add at least a mirror (RAID 1/ZFS mirror) for irreplaceable data, or an additional parity drive for larger arrays.
Storage risk
Riesgo: lowSolid-state storage — no moving parts, low mechanical failure risk.
Solución: For an always-on system, prefer NAS/CMR-rated drives; monitor SMART and replace before the warranty ends.
Data loss risk
Riesgo: high1 drive(s) with no redundancy — a single SSD/controller failure can still lose data.
Solución: Add redundancy and an off-site/off-box backup for anything irreplaceable.
Power risk
Riesgo: lowPSU is 650W, peak load 193W (30%).
Solución: PSU sizing leaves healthy headroom for spikes and future parts.
Network risk
Riesgo: lowSingle 2500 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 2500 Mbps.
Solución: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.
Expansion risk
Riesgo: low1 PCIe, 2 M.2, 4 SATA, 2 bays free.
Solución: Healthy room for future drives, NICs and accelerators.
Upgrade risk
Riesgo: low2024 platform — current generation with a forward-looking socket/feature set.
Solución: 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 (1372€) exceeds your budget (1100€) by 272€ (25%). Ranking already prefers in-budget variants — this one is shown for comparison; check the value variant or raise the budget.
Acción: Reconsider the config for the stated workload or budget before buying.
Categoría: balance
No storage redundancy
Crítico1 drive(s) with no mirror or parity for the data you plan to store.
Acción: Add at least a mirror for irreplaceable data before you migrate anything.
Categoría: storage
Keep a backup off-box
OpcionalRedundancy inside the box does not survive fire, theft or a whole-array fault.
Acción: Mirror the important data to an external drive, a second box, or cloud.
Categoría: storage
More VRAM for AI
OpcionalLocal AI/inference benefits strongly from 16GB+ VRAM.
Acción: Consider a higher-VRAM GPU if AI is a serious goal.
Categoría: ai
Drive bays remain
Futuro2 drive bay(s) free for future capacity.
Acción: Expand capacity in pairs (mirror/parity) when needed.
Categoría: storage
PCIe slot available
Futuro1 free PCIe slot(s) for a NIC, HBA or GPU later.
Acción: Use it for a 10G NIC, extra HBA, or an accelerator when the need appears.
Categoría: expansion
Nothing obvious becomes a limiting factor in the near term — this build should age well.
CPU is the closest to its limit (75% of capacity in use) — it will likely force the next upgrade.
