Bill of materials
Parts & purchasing
Buy in a deliberate order so you are never stranded with incompatible or expensive parts. DIY totals land roughly $445–$1,000; a complete 1-to-7 tower often lists around $475–$548, so DIY wins mainly when shipping assembled towers is painful or metalwork is local.
Required parts
| Qty | Part | Minimum specification | Selection notes & links |
|---|---|---|---|
| 1 | Standalone duplicator controller | 1 source + 7 target native-SATA channels; LCD/keypad; CD-DA; speed select; verify; firmware update | ACARD 1-to-7 class or Vinpower/Copystars equivalent. Confirm revision + drive compatibility. |
| 8 | SATA optical writers | Full-height 5.25-inch, tray-loading, CD-R 48X/52X, CD-RW | Same model and preferably same firmware lot. One source + seven targets. |
| 1 | Primary enclosure | Nine bays (one-box) or five bays (split) | Metal preferred for grounding and EMI. |
| 0–1 | Satellite enclosure | Four 5.25-inch bays | Split build only. Rigid mount + rear exhaust. |
| 1–2 | Power supplies | Quality ATX; strong 5 V and 12 V rails | 400–500 W one-box; or 250–350 W + 200–300 W split. Prefer listed brands with OCP/OVP. |
| 8 | SATA data cables | Latching, 30–60 cm inside a tower | Shortest practical length; avoid sharp bends. |
| 4 ch | Remote data-link hardware | Shielded external + secured bulkheads; path < 1 m | Split only. One channel per remote drive. |
| 2–4 | Cooling fans | 120 mm ball- or fluid-bearing with guards | Front/bottom intake, rear/top exhaust. |
| 1 | Power-switch solution | ATX switch board or controller harness | Both enclosures powered before drive detection. |
| 0–1 | Dual-PSU synchronizer | Listed relay or ATX dual-PSU sync module | Split build preferred startup method. |
| 1 | AC protection | Quality surge strip or UPS | Required for production reliability. Microboards documents a protected strip or UPS. |
| 1 set | Hardware | M3 screws, standoffs, grommets, strain reliefs, ties | Never pass cables through raw sheet-metal holes. |
| 1 | Test media lot | Known-quality CD-R, ≥ 50 discs | Qualify one lot before production. Prefer CMC Pro / Taiyo Yuden-technology printable discs. |

Purchasing sequence
- Controller with return rights and exact manual/firmware revision
- One candidate writer
- Quality CD-R media for qualification
- Remaining seven matching writers after the sample passes
- Local enclosure or used chassis
- PSU, fans, and ordinary internal cabling
- Split-enclosure bulkheads/links only if one-box remains impractical
- One spare writer from the same lot for paid production
Avoid untested assortments of used burners. Eight mismatched firmware lots can cost more in failed media than one matched set.
