**Passepartout Server — Build BOM & Phased Plan**

- Chassis: CX4712 ($439 Sliger)
- CPU: EPYC 7002 Rome SP3 (~$100-200 used)
- Board: Supermicro H11SSL-i (~$150 used)
- Cooler: Asetek 836SA-M1 AIO ($250 Sliger add-on)
- GPUs: 2x used RTX 3090 (~$750 ea)
- RAM: 256GB via 8x 32GB Crucial DDR4-3200 ECC ($210/ea)
- PSU: Corsair RM1000e 1000W ($148)
- Fans: 3x Noctua NF-A12x25 PWM ($75 Sliger)
- Rails: Sliger 20" rack slides ($109)
- HBA: LSI 9300-8i IT mode ($75)
- Boot NVMe: 1TB (~$60)
- ZFS special vdev: 2x 512GB NVMe mirrored (~$50/ea)
- HDDs: 6x 20-24TB recertified (~$250-350/ea)

Total estimate: ~$5,900

**Phased buying plan (~$1K per phase)**

1. EPYC CPU + SP3 motherboard (~$250) — test boot
2. CX4712 + PSU + fans + AIO + rails + NVMe boot + HBA (~$1,156)
3. 128GB RAM (4x32GB Crucial) + 1st RTX 3090 (~$1,590)
4. 4x 20-22TB HDDs recertified (~$1,200)
5. 128GB more RAM + 2nd RTX 3090 + 2x 512GB NVMe (~$1,690)

**Stages**

- Now: All-in-one (compute + storage + inference)
- Future: Proxmox secondary node when 3 better nodes appear
- Final: Backup server (just HDDs + ZFS)
