Future-proof score
Strong future-proofing83/100
Strong future-proofing (83/100) — this build should stay relevant for years without major surgery.
DIY build — the CPU, motherboard and PSU can each be upgraded independently without replacing the whole system.
Expansion headroom: 3 PCIe slot(s), 3 M.2, 4 SATA, 2 drive bay(s), 2 RAM slot(s) free.
Storage is 0% utilized with 2 free drive bay(s) and 4 free SATA port(s).
2 RAM slot(s) free; memory is 50% utilized.
Networking is 5000 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 (the iGPU handles transcoding), but there is room (3 PCIe slot(s), PSU headroom 2.8x) to add one for AI.
Homelab Risk Score
Low risk10/100
Low risk (10/100) — sensible redundancy and headroom; no single point of failure is exposed.
Final build audit
Audit passed (0 critical, 0 warning) — mostly optional and future considerations remain.
What becomes the limit
Nothing obvious becomes a limiting factor in the near term — this build should age well.
What limits you first
RAM is the closest to its limit (50% of capacity in use) — it will likely force the next upgrade.
