Warum diese Variante
Wähle sie, wenn
Balances your priorities with a 1530€ price tag and a 36W idle draw.
Was sie opfert
- Not specialized: it does not push any single dimension (value, silence, expansion) to the extreme.
Wie die Teile gewählt wurden
- Intel Core i7 14700: 20 cores / 28 threads covers the 11 cores needed with headroom.
- Motherboard Intel B760 (LGA 1700): matches the CPU socket and case size.
- RAM: 64GB DDR5,DDR4 — meets the 64GB the workload requires.
Warum nicht die anderen
- All variants are close; the winner matches your priorities best.

Check the balance
This build may struggle with the stated workload.
Kritisch
No storage redundancy
1 drive(s) with no mirror or parity for the data you plan to store.
Kritisch
RAM is nearly exhausted
The workload needs 100% of available RAM — swapping will hurt.

Zukunftssicherheits-Score
Starke Zukunftssicherheit83/100
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: 3 PCIe slot(s), 6 M.2, 4 SATA, 2 drive bay(s), 2 RAM slot(s) free.
Storage growth90
Storage is 100% utilized with 2 free drive bay(s) and 4 free SATA port(s).
Memory growth75
2 RAM slot(s) free; memory is 100% 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, but there is room (3 PCIe slot(s), PSU headroom 3.8x) to add one for AI/transcoding.
Homelab-Risiko-Score
Mäßiges Risiko37/100
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.Lösung: 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.Lösung: 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.Lösung: Add redundancy and an off-site/off-box backup for anything irreplaceable.
low
Power risk
PSU is 400W, peak load 104W (26%).Lösung: 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.Lösung: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.
low
Expansion risk
3 PCIe, 6 M.2, 4 SATA, 2 bays free.Lösung: Healthy room for future drives, NICs and accelerators.
low
Upgrade risk
2024 platform — current generation with a forward-looking socket/feature set.Lösung: Buy for the workload, not the socket — upgrade paths are a bonus, not a guarantee.

Redundancy inside the box does not survive fire, theft or a whole-array fault.Aktion: Mirror the important data to an external drive, a second box, or cloud.storage

Was zum Limit wird
RAM is tight is the most likely thing to date this build within 1-2y.
1-2y
RAM is tight
Warum: Memory is 100% utilized — a growing workload will hit the ceiling quickly.Was zu tun ist: Add the remaining RAM before prices change, while slots are free.
1-2y
Storage nearly full
Warum: 100% of raw capacity is already in use — media libraries and backups grow fast.Was zu tun ist: Expanding is easy: add a drive to the free bays/ports.
Was dich zuerst begrenzt
RAM is the closest to its limit (100% of capacity in use) — it will likely force the next upgrade.
