Porquê esta variante
Escolha-a se
Balances your priorities with a 2703€ price tag and a 63W idle draw.
O que sacrifica
- Not specialized: it does not push any single dimension (value, silence, expansion) to the extreme.
Como as peças foram escolhidas
- Intel Core i7 14700: 20 cores / 28 threads covers the 18 cores needed with headroom.
- Motherboard Intel B760 (LGA 1700): matches the CPU socket and case size.
- RAM: 128GB DDR5,DDR4 — meets the 96GB the workload requires.
Porque não as outras
- All variants are close; the winner matches your priorities best.

3 críticosCrítico
Check the balance
This build may struggle with the stated workload.
Crítico
No storage redundancy
1 drive(s) with no mirror or parity for the data you plan to store.
Crítico
CPU close to the limit
The workload uses 90% of the CPU — little headroom for background tasks or growth.

Pontuação de prova de futuro
Prova de futuro forte77/100
Strong future-proofing (77/100) — this build should stay relevant for years without major surgery.
Upgrade path75
DIY build — the CPU, motherboard and PSU can each be upgraded independently without replacing the whole system.
Expansion100
Expansion headroom: 2 PCIe slot(s), 6 M.2, 4 SATA, 2 drive bay(s), 0 RAM slot(s) free.
Storage growth90
Storage is 75% utilized with 2 free drive bay(s) and 4 free SATA port(s).
Memory growth20
0 RAM slot(s) free; memory is 75% utilized.
Networking80
Networking is 2500 Mbps, and a free PCIe slot can add a faster NIC later.
Replacement ease90
ATX form factor with standard, socketed components — most parts are easy to replace.
Workload change85
A 16GB GPU is present — AI and transcoding workloads are covered.
Homelab Risk Score
Risco moderado37/100
Moderate risk (37/100) — a few items are worth fixing before you commit (see checklist).
critical
Single point of failure
All 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.
low
Storage risk
Solid-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.
high
Data loss risk
1 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.
low
Power risk
PSU is 500W, peak load 283W (57%).Solução: PSU sizing leaves healthy headroom for spikes and future parts.
low
Network risk
Single 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.
low
Expansion risk
2 PCIe, 6 M.2, 4 SATA, 2 bays free.Solução: Healthy room for future drives, NICs and accelerators.
low
Upgrade risk
2024 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.
Auditoria final do build

Check the balance

Crítico
No storage redundancy
1 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.storage
Crítico
CPU close to the limit
The workload uses 90% of the CPU — little headroom for background tasks or growth.Ação: Consider a stronger CPU or drop a secondary workload.compute
Opcional
Keep a backup off-box
Redundancy 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.storage
Futuro
Drive bays remain
2 drive bay(s) free for future capacity.Ação: Expand capacity in pairs (mirror/parity) when needed.storage
Futuro
PCIe slot available
2 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.expansion
O que se torna o limite
RAM is maxed out is the most likely thing to date this build within 1-2y.
1-2y
RAM is maxed out
Porquê: All RAM slots are used and the workload already sits at 75% — the next memory need means replacing kits or a new build.O que fazer: Buy a single larger kit now, or plan the RAM for the full lifecycle.
1-2y
Storage nearly full
Porquê: 75% of raw capacity is already in use — media libraries and backups grow fast.O que fazer: Expanding is easy: add a drive to the free bays/ports.
1-2y
CPU is the next bottleneck
Porquê: The CPU runs at 90% of capacity — new services or more users will hit the wall first.O que fazer: Consider a stronger CPU within the same socket generation while it is still cheap.
O que o limita primeiro
CPU is the closest to its limit (90% of capacity in use) — it will likely force the next upgrade.
