Why this variant
Choose it if
The lowest total price (997€) that still covers this workload properly — best price/quality ratio.
It sacrifices
- 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.
How the parts were chosen
- AMD Ryzen 5 5600GT: 6 cores / 12 threads covers the 6 cores needed with headroom.
- Motherboard AMD B550 (AM4): matches the CPU socket and case size.
- RAM: 32GB DDR4 — meets the 24GB the workload requires.
Why not the others
- Value build — most for your money beats "Smart build — best all-round" on performance -21, value +9, silence -23, longevity -5 — that is why it is recommended for your priorities.
Before you buy
Warning
Review
System idles ~35W vs maxIdlePowerW=30W requested (CPU ~8W + drives/fans). Closest efficient option shown — lower the workload or raise the cap for full compliance.
Warning
No storage redundancy
3 drive(s) with no mirror or parity for the data you plan to store.

Future-proof score
Strong future-proofing83/100
Strong future-proofing (83/100) — 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: 1 PCIe slot(s), 0 M.2, 3 SATA, 9 drive bay(s), 2 RAM slot(s) free.
Storage growth90
Storage is 71% utilized with 9 free drive bay(s) and 3 free SATA port(s).
Memory growth75
2 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 change70
No GPU (the iGPU handles transcoding), but there is room (1 PCIe slot(s), PSU headroom 6.2x) to add one for AI.
Homelab Risk Score
Moderate risk41/100
Moderate risk (41/100) — a few items are worth fixing before you commit (see checklist).
high
Single point of failure
Storage has no redundancy (3 drives, no mirror/parity) — a single drive failure exposes the array.Fix: Add at least a mirror (RAID 1/ZFS mirror) for irreplaceable data, or an additional parity drive for larger arrays.
medium
Storage risk
1 desktop hard drive(s) — not rated for 24/7 duty, vibration or heat; higher long-run failure risk.Fix: For an always-on system, prefer NAS/CMR-rated drives; monitor SMART and replace before the warranty ends.
critical
Data loss risk
3 drive(s), no redundancy, hard-drive media — the worst combination for keeping data safe.Fix: Add redundancy and an off-site/off-box backup for anything irreplaceable.
low
Power risk
PSU is 650W, peak load 105W (16%).Fix: 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.Fix: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.
low
Expansion risk
1 PCIe, 0 M.2, 3 SATA, 9 bays free.Fix: Healthy room for future drives, NICs and accelerators.
low
Upgrade risk
2024 platform — current generation with a forward-looking socket/feature set.Fix: Buy for the workload, not the socket — upgrade paths are a bonus, not a guarantee.

Optimization
Use NAS-rated drives
Desktop drives in an always-on NAS/server role have higher long-run failure rates.Action: Prefer NAS/CMR-rated drives for 24/7 duty.storage
Optional
Add a UPS
An always-on server holding data should survive power blips.Action: Add a line-interactive UPS sized for the build's peak draw (≥ 10 min at typical load for a clean shutdown).power
Optional
Keep a backup off-box
Redundancy 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.storage

RAM expansion available
2 RAM slot(s) free for a later upgrade.Action: Leave them free until the workload actually grows.memory

Drive bays remain
9 drive bay(s) free for future capacity.Action: Expand capacity in pairs (mirror/parity) when needed.storage

PCIe slot available
1 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.expansion
What becomes the limit
CPU is the next bottleneck is the most likely thing to date this build within 1-2y.
1-2y
CPU is the next bottleneck
Why: The CPU runs at 100% of capacity — new services or more users will hit the wall first.What to do: Consider a stronger CPU within the same socket generation while it is still cheap.
3-5y
Storage growing
Why: 71% of capacity in use — comfortable today, tighter over a few years.What to do: Plan the growth curve; keep at least one bay free for the next drive.
What limits you first
CPU is the closest to its limit (100% of capacity in use) — it will likely force the next upgrade.
