Fremtidssikkerhedsscore

Stærk fremtidssikkerhed

80/100

Strong future-proofing (80/100) — 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.

Expansion88

Expansion headroom: 2 PCIe slot(s), 2 M.2, 4 SATA, 0 drive bay(s), 2 RAM slot(s) free.

Storage growth90

Storage is 50% utilized with 0 free drive bay(s) and 4 free SATA port(s).

Memory growth75

2 RAM slot(s) free; memory is 50% utilized.

Networking55

Networking is 1000 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 32GB GPU is present — AI and transcoding workloads are covered.

Homelab Risk Score

Lav risiko

24/100

Low risk (24/100) — sensible redundancy and headroom; no single point of failure is exposed.

low

Single point of failure

No primary data stored on this system, so a drive failure has low impact.Løsning: Keep backups for any data you do add later.

low

Storage risk

Solid-state storage — no moving parts, low mechanical failure risk.Løsning: 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.Løsning: Add redundancy and an off-site/off-box backup for anything irreplaceable.

low

Power risk

PSU is 1000W, peak load 753W (75%).Løsning: PSU sizing leaves healthy headroom for spikes and future parts.

medium

Network risk

Single 1000 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 1000 Mbps.Løsning: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.

low

Expansion risk

2 PCIe, 2 M.2, 4 SATA, 0 bays free.Løsning: Healthy room for future drives, NICs and accelerators.

low

Upgrade risk

2026 platform — current generation with a forward-looking socket/feature set.Løsning: Buy for the workload, not the socket — upgrade paths are a bonus, not a guarantee.

Endelig build-audit

Audit passed (0 critical, 0 warning) — mostly optional and future considerations remain.

1 Optimering2 Valgfrit2 Fremtid

Optimering

Plan faster networking

1G networking is fine today but will bottleneck multi-user media or big NAS transfers at 1TB.Handling: Budget for a 2.5G/10G NIC and switch later, or spec it now.network

Valgfrit

Back up what you keep

No data pool on this build: a drive failure costs a reinstall, not your files.Handling: Keep saves, configs and projects in a cloud or external backup.storage

Valgfrit

Keep a backup off-box

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

Fremtid

RAM expansion available

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

Fremtid

PCIe slot available

2 free PCIe slot(s) for a NIC, HBA or GPU later.Handling: Use it for a 10G NIC, extra HBA, or an accelerator when the need appears.expansion

Hvad bliver grænsen

Storage growing is the most likely thing to date this build within 3-5y.

3-5y

Storage growing

Hvorfor: 50% of capacity in use — comfortable today, tighter over a few years.Hvad du skal gøre: Plan the growth curve; keep at least one bay free for the next drive.

3-5y

1G networking becomes the ceiling

Hvorfor: A 1000 Mbps link will cap NAS transfers and multi-user media before the CPU or disks do.Hvad du skal gøre: Add a 2.5G/10G NIC when the switch investment makes sense.
