My New Home Lab Build - What Am I Missing?
My New Home Lab Build - What Am I Missing?
Hey everyone! Just finished sourcing parts for my new home lab build and wanted to get some feedback from the community. Coming from a Dell R730xd (2U rackmount, loud as hell) and upgrading to something quieter and more powerful.
My Use Case
- Web pentesting & binary vulnerability research (fuzzing, exploit dev)
- ESXi virtualization host
- Multiple Windows VMs for development
- Kali + various target/lab VMs
- Self-hosted GitLab
- Personal knowledge base
- Home Assistant for IoT (Tuya devices)
- Local AI inference (Ollama + open source LLMs)
The Build
| Component | Spec |
|---|---|
| CPU | 2x AMD EPYC 7J13 (64C/128T each, 128C/256T total) |
| Motherboard | Supermicro H12DSi-N6 (Dual SP3, 16 DIMM slots) |
| RAM | 64GB DDR4 ECC RDIMM (reused from old server, planning to upgrade to 256GB+) |
| Cooling | 360mm AIO liquid cooler, dual pump heads |
| Case | Fractal Design Define 7 XL |
| PSU | Seasonic 1000W 80+ Gold |
| Boot/VM Drive | Samsung 980 PRO 2TB NVMe |
| Data Drives | 4x 2.5" SATA (reused from R730xd) |
| Network | Onboard 2x 1GbE Intel I210 + IPMI |
| OS | VMware ESXi 8.0 |
Total cost: ~$1,950 USD (¥14,190 CNY) — all sourced second-hand except the NVMe.
What I'm Happy With
- 128 cores for fuzzing and parallel VM workloads
- Silent operation (AIO + Define 7 XL sound-dampened case)
- IPMI for remote management
- Huge upgrade from my old Broadwell E5-2683 v4 setup (~5-6x multi-core improvement)
What I'm Considering Adding
- 10GbE NIC (Intel X710?) for faster NAS connectivity
- More RAM (256-512GB DDR4 3200 ECC RDIMM)
- GPU for AI inference (Tesla P40 24GB or RTX 3090?)
- Dedicated NVMe storage for VMs (additional M.2 via PCIe adapter?)
Questions for the Community
- Any recommendations for a good 10GbE NIC that works well with ESXi on this platform?
- For those running dual EPYC on ESXi — any gotchas I should know about?
- Is a GPU worth it for local LLM inference, or is 128 cores of Zen3 "good enough" for 7B-14B models?
- Any suggestions for my network topology? Currently running OpenWrt on a dedicated x86 box in the patch panel, 16-port PoE switch, Synology NAS.
- What else would you add to this setup?
Thanks in advance! Happy to answer any questions about the build.
