Based on your goals you need roughly 8 CPU threads, 62GB RAM and 4TB of storage. This system runs 24/7, so energy matters. Recommended: the Value build — most for your money — 756€ purchase, ~34W idle, ~113€/year energy (≈338€ over 3 years). Intel Core i3 14100F: 8 threads covers the 8 needed with headroom. Motherboard Intel H610 (LGA 1700): matches the CPU socket and case size. RAM: 64GB DDR4 — meets the 62GB the workload requires. Chose Intel Core i3 14100F over AMD Ryzen 3 4100: better overall fit for your priorities. Build DNA: performance 70, value 96, efficiency 74, expandability 84, silence 85, longevity 95 — overall 89/100. Heads-up: Requested 2500 Mbps but board Intel H610 has max 1000 Mbps onboard and no free PCIe slot — staying on onboard networking. Add a board with a free slot for 2.5G/10G. This build may struggle with the stated workload. What limits you first: CPU. Alternatives: Smart build — best all-round — 1695€, DNA 92/100, balanced · Long-term build — expandable & future-proof — 1695€, DNA 92/100, balanced.
The system as a whole — before the shopping list.

We split your build into the performance you need, the performance you're buying, and the performance you're likely to use day-to-day. When the gap is wide, you're overbuying.
The build is tight on resources for the stated workload — it may struggle under load.

What this means
An explainable future-proof score, the Homelab Risk Score, a final pre-purchase audit and what will become the limiting factor over time.
Balanced future-proofing
Balanced future-proofing (63/100) — it covers today's workload with some room, but one or two factors will push you to upgrade sooner.
DIY build — the CPU, motherboard and PSU can each be upgraded independently without replacing the whole system.
Expansion headroom: 2 PCIe slot(s), 2 M.2, 0 SATA, 2 drive bay(s), 0 RAM slot(s) free.
Storage is 50% utilized with 2 free drive bay(s) and 0 free SATA port(s).
0 RAM slot(s) free; memory is 98% utilized.
Networking is 1000 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.
No GPU, but there is room (2 PCIe slot(s), PSU headroom 6.7x) to add one for AI/transcoding.
Moderate risk
Moderate risk (46/100) — a few items are worth fixing before you commit (see checklist).
Single point of failure
Risk: criticalAll data sits on a single drive with no redundancy — one failure means total loss.
Fix: Add at least a mirror (RAID 1/ZFS mirror) for irreplaceable data, or an additional parity drive for larger arrays.
Storage risk
Risk: lowSolid-state storage — no moving parts, low mechanical failure risk.
Fix: For an always-on system, prefer NAS/CMR-rated drives; monitor SMART and replace before the warranty ends.
Data loss risk
Risk: high1 drive(s) with no redundancy — a single SSD/controller failure can still lose data.
Fix: Add redundancy and an off-site/off-box backup for anything irreplaceable.
Power risk
Risk: lowPSU is 650W, peak load 97W (15%).
Fix: PSU sizing leaves healthy headroom for spikes and future parts.
Network risk
Risk: criticalThe workload wants 2500 Mbps but the config only provides 1000 Mbps.
Fix: Add a 2.5G NIC or upgrade the platform.
Expansion risk
Risk: low2 PCIe, 2 M.2, 0 SATA, 2 bays free.
Fix: Healthy room for future drives, NICs and accelerators.
Upgrade risk
Risk: low2024 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.
Audit found 5 critical and 0 warning item(s) worth fixing before you buy.
Check the balance
CriticalRequested 2500 Mbps but board Intel H610 has max 1000 Mbps onboard and no free PCIe slot — staying on onboard networking. Add a board with a free slot for 2.5G/10G.
Action: Reconsider the config for the stated workload or budget before buying.
Category: balance
Check the balance
CriticalThis build may struggle with the stated workload.
Action: Reconsider the config for the stated workload or budget before buying.
Category: balance
No storage redundancy
Critical1 drive(s) with no mirror or parity for the data you plan to store.
Action: Add at least a mirror for irreplaceable data before you migrate anything.
Category: storage
CPU close to the limit
CriticalThe workload uses 100% of the CPU — little headroom for background tasks or growth.
Action: Consider a stronger CPU or drop a secondary workload.
Category: compute
RAM is nearly exhausted
CriticalThe workload needs 98% of available RAM — swapping will hurt.
Action: Add more RAM now, while slots are still free.
Category: memory
Plan faster networking
Optimization1G networking is fine today but will bottleneck multi-user media or big NAS transfers at 4TB.
Action: Budget for a 2.5G/10G NIC and switch later, or spec it now.
Category: network
Add a UPS
OptionalAn always-on server holding data should survive power blips.
Action: Add an online/line-interactive UPS sized to the build's idle draw.
Category: power
Keep a backup off-box
OptionalRedundancy 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.
Category: storage
Drive bays remain
Future2 drive bay(s) free for future capacity.
Action: Expand capacity in pairs (mirror/parity) when needed.
Category: storage
PCIe slot available
Future2 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.
Category: expansion
RAM is maxed out is the most likely thing to date this build within 1-2y.
RAM is maxed out
Why: All RAM slots are used and the workload already sits at 98% — the next memory need means replacing kits or a new build.
What to do: Buy a single larger kit now, or plan the RAM for the full lifecycle.
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.
Storage growing
Why: 50% 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.
1G networking becomes the ceiling
Why: A 1000 Mbps link will cap NAS transfers and multi-user media before the CPU or disks do.
What to do: Add a 2.5G/10G NIC when the switch investment makes sense.
CPU is the closest to its limit (100% of capacity in use) — it will likely force the next upgrade.
