unknown
A required fact, input, effective source, or deferred test is missing.
Documented prerequisite fit only. Stream stability, quality, tone mapping, codec coverage, and concurrent throughput require Grade A lab results.

decision breakdown by axis
decision breakdown
- memory
- conditional
- Installed memory meets Jellyfin's general recommendation. The positive match is supported only by a modeled, inferred, or user-attested Grade D value, so it remains Conditional and cannot establish a Yes verdict.
- evidence grade d · modeled or inferred
- media
- unknown
- The modeled processor includes Intel Quick Sync. The positive match is supported only by a modeled, inferred, or user-attested Grade D value, so it remains Conditional and cannot establish a Yes verdict.
- evidence grade d · modeled or inferred
- storage
- unknown
- The modeled system drive is SSD-class storage. The positive match is supported only by a modeled, inferred, or user-attested Grade D value, so it remains Conditional and cannot establish a Yes verdict.
- evidence grade d · modeled or inferred
- network
- conditional
- The modeled wired interface meets the documented recommendation. The positive match is supported only by a modeled, inferred, or user-attested Grade D value, so it remains Conditional and cannot establish a Yes verdict.

physical selection constraints
- The 2.5-inch SATA drive and PCIe card cannot be installed together — Lenovo documents the M720 Tiny 2.5-inch HDD/SSD and PCIe card as mutually exclusive. Installing a PCIe riser/card consumes the space used by the 2.5-inch drive assembly. The modeled selections do not conflict, but Grade D configuration identity cannot prove the physical assembly clear. Resolution: Choose the internal 2.5-inch SATA drive or the PCIe riser/card. Keep NVMe as the internal storage path when PCIe expansion is required.

unknowns and contradictions (6)
- The GPU device and correct drivers must be configured and passed through. The required input or capability is unknown.
- Confirm media storage whose sequential throughput exceeds the source bitrate before treating the workload as complete. The required input or capability is unknown.
- compute is not evaluated by this recipe.
- virtualization is not evaluated by this recipe.
- power thermals is not evaluated by this recipe.
- operational is not evaluated by this recipe.
what this result will not tell you
best-value upgrade
unavailable without current price evidence
The pilot has no fresh, comparable acquisition prices, so it will not label an upgrade as the best value.
why we believe this (4 evidence records)
a grade describes how well attested a statement is, not how good the hardware is. grade a is a lab run we reproduced with a published method. grade d is a model, a reasoned inference, or a single unverified report.
- evidence grade b 3 records
- evidence grade d 1 record
evidence grade b · official sourcesupports
Jellyfin recommends 8 GB RAM, SSD storage for application data and transcode cache, wired gigabit networking, and properly configured hardware acceleration for transcoding.
evidence grade b · official sourcesupports
The M720 Tiny family supports i5-8500T configurations, two DDR4-2666 SO-DIMM slots, an M.2 SSD, and an optional 2.5-inch SATA drive; Lenovo specifies that the 2.5-inch HDD/SSD and PCIe card are mutually exclusive.
evidence grade b · official sourcesupports
The i5-8500T has 6 cores, 6 threads, Intel 64, AVX2, UHD Graphics 630, Quick Sync Video, VT-x, VT-d, and EPT.

comparable verified setups
No other exact configuration has an accepted Grade A run for this workload. Modeled checker results are not presented as verified comparisons, and any future run must share the same protocol and fixture before it is treated as directly comparable.
how to use this answer
- Resolve every “must be answered” assumption on the actual machine.
- Confirm the actual hardware matches the modeled configuration identity.
- Inspect the limiting factor — and whether it is a capability limit, an assumption limit, or an evidence gap — rather than converting the result into a score.
- Do not treat prerequisite fit as measured stream quality or throughput.
Accepted Grade A records attached to this pair: 0. The candidate result exposes official requirements, modeled inputs, and missing facts. Any measured claim remains limited to the fixture and scope of its attached run.
