Por que estou realmente a pagar?
Dividimos o teu build no desempenho de que precisas, o que compras e o que provavelmente usarás no dia a dia. Quando a diferença é grande, estás a comprar demais.
UNDERPOWERED — o build pode ter dificuldades com a carga declarada.
| Desempenho de que preciso | Desempenho que compro | Provavelmente usarei | |
|---|---|---|---|
| Threads de CPU | 12 | 12 | 8 |
| RAM | 80 | 128 | 64 |
| Armazenamentooverbuy | 3 | 8 | 3 |
| VRAM de GPU | 16 | 16 | 16 |
| Rede | 2.5G | 1.0G | 1.0G |
O que significa
- You're paying for 8TB storage when the workload needs 3TB — 2.7x the requirement.
- The build is under-powered for the stated workload — it may struggle under load.
Pontuação e riscos
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.
Pontuação de prova de futuro
Prova de futuro forte
73
Strong future-proofing (73/100) — 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.
Expansion72
Expansion headroom: 2 PCIe slot(s), 1 M.2, 6 SATA, 0 drive bay(s), 0 RAM slot(s) free.
Storage growth90
Storage is 38% utilized with 0 free drive bay(s) and 6 free SATA port(s).
Memory growth20
0 RAM slot(s) free; memory is 63% 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 moderado
37
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 600W, peak load 123W (21%).
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: low2 PCIe, 1 M.2, 6 SATA, 0 bays free.
Solução: Healthy room for future drives, NICs and accelerators.
Upgrade risk
Risco: low2022 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
Audit found 3 critical and 0 warning item(s) worth fixing before you buy.
3 Crítico0 Aviso0 Otimização1 Opcional1 Futuro
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
CPU close to the limit
CríticoThe workload uses 100% of the CPU — little headroom for background tasks or growth.
Ação: Consider a stronger CPU or drop a secondary workload.
Categoria: compute
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
PCIe slot available
Futuro2 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
O que se torna o limite
RAM is maxed out is the most likely thing to date this build within 1-2y.
Horizonte: 1-2y
RAM is maxed out
Porquê: All RAM slots are used and the workload already sits at 63% — 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.
Horizonte: 1-2y
CPU is the next bottleneck
Porquê: The CPU runs at 100% 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.

Porquê este build
- AMD Ryzen 5 5500: 12 threads covers the 12 needed with headroom.
- Motherboard AMD B550 (AM4): matches the CPU socket and case size.
- RAM: 128GB DDR4 — meets the 80GB the workload requires.
- AMD Radeon RX 6950 XT Liquid Devil Overclocked Liquid Cooled 16GB GDDR6 PCIe 4.0 Graphics Card: 16GB VRAM selected for your ai GPU need.
- Chose AMD Ryzen 5 5500 over AMD Ryzen 5 9600: better overall fit for your priorities.
Quem o deve escolher
- The lowest total price (1902€) that still covers this workload properly — best price/quality ratio.
Porquê não a alternativa
- Value build — most for your money beats "Smart build — best all-round" on performance -30, value +40, efficiency +51, expandability -7 — that is why it is recommended for your priorities.
- Value build — most for your money beats "Long-term build — expandable & future-proof" on performance -30, value +40, efficiency +22, expandability -7 — that is why it is recommended for your priorities.
O que sacrifica
- No ECC memory — fine for home use, less ideal for bit-rot-sensitive archives.
- Expansion headroom is trimmed: parts are chosen for price per capability.
- All drive bays are used — adding storage later means replacing drives.
O que te limita primeiro
CPU is the closest to its limit (100% of capacity in use) — it will likely force the next upgrade.
Próximos upgrades
- Upgrade storage to Western Digital WD Red Pro 26TB 3.5" HDD 7200RPM SATA 6.0 Gb/s
- Upgrade cpu to Intel Core i5 14400F
- Upgrade motherboard to MSI B850 PRO B850M-VC WIFI6E AM5 DDR5 Micro ATX
