Quick verdict
| You’re… | Buy this |
|---|---|
| Building a low‑power Proxmox node that can handle on‑the‑fly video transcoding. | Beelink SER8 (affiliate) – great performance per watt, quiet chassis, built‑in 2.5 GbE and Radeon GPU for hardware transcode. |
| On a shoestring budget, need a reliable used box to run containers or basic VMs. | Dell OptiPlex Micro (affiliate) – cheap entry point, solid Intel reliability, enough expandability for modest workloads. |
Spec‑by‑spec comparison
| Feature | Beelink SER8 | Dell OptiPlex Micro |
|---|---|---|
| Category | Mini PC | Mini PC (used) |
| Price | $500 | $150 |
| Best for | Proxmox mini server | Cheap used homelab |
| CPU | AMD Ryzen 7 8845HS – 8 cores / 16 threads, integrated Radeon 780M | Intel Core i5 (8th‑10th gen, used) – 4‑6 cores depending on exact SKU |
| RAM support | Up to 32 GB DDR5 | 8–32 GB DDR4 |
| Network | 1× 2.5 GbE | 1× 1 GbE |
| Hardware transcode | Yes – Radeon 780M GPU | Yes – Intel UHD graphics |
| Storage expansion | NVMe (low PCIe) | 1× NVMe + 1× SATA |
| Pros | Great perf/watt, quiet operation | Cheap, reliable, quiet |
| Cons | Limited PCIe lanes for add‑ons | Used hardware, older CPU generation |
Performance & power efficiency
The Beelink SER8 packs an AMD Ryzen 7 8845HS. Even though we can’t quote clock speeds, the “great perf/watt” note tells us this silicon is designed to deliver strong compute capability while staying frugal on electricity—a perfect match for a Proxmox node that may run 24/7. The integrated Radeon 780M also gives you hardware‑accelerated video transcode out of the box, which can be a lifesaver if you plan to stream media or run Plex.
The Dell OptiPlex Micro leans on an Intel Core i5 from the 8th‑10th generations. While older than the Ryzen chip, it’s still capable for everyday container workloads and light VM hosting. Its “quiet” reputation means no noisy fans rattling in a home office. However, you won’t get the same raw performance per watt or GPU‑assisted transcode that the SER8 offers.
Expansion & connectivity
Networking can be a bottleneck when multiple VMs talk to each other or pull large data sets from NAS devices. The SER8’s 2.5 GbE port gives you roughly double the bandwidth of the OptiPlex Micro’s 1 GbE, which is especially useful for storage‑intensive Proxmox clusters.
On storage, both boxes support NVMe drives, but the Dell adds a SATA slot—handy if you already have an old SSD or want to attach a modest HDD for backups. The SER8 mentions “low PCIe,” meaning it has fewer lanes for additional cards; you’ll likely be limited to just the internal NVMe and perhaps a USB‑C expansion dongle.
Use‑case fit
| Scenario | Ideal pick |
|---|---|
| Proxmox with multiple VMs, occasional media streaming | Beelink SER8 – higher CPU thread count, DDR5 support, 2.5 GbE, GPU transcode. |
| Lightweight containers or a single VM for home automation | Dell OptiPlex Micro – cheap entry price, enough RAM headroom, reliable Intel platform. |
| Budget‑first deployment where you can replace parts later | Dell OptiPlex Micro – low upfront cost; you can upgrade to the SATA slot later. |
