Amiga 4000 Small Form Factor Power Supply adapter. This design solves problems related to switching to an SFF power supply. This design provides a platform for a small form factor power supply to sit on, it provides an attachment point for a power switch, and it closes up the gap under the SFF power supply at the back of the machine. The open design and air holes on one side allow for better airflow, which should help to reduce the internal temps of the case by a large degree. As a side benefit, the supports of the hard drive caddy rest on top of the power supply, just like the original design. made out of High temp resistant ABS Use a Corsair SFF 450 power supply. Also use an ATX power supply adapter/switch from Amigakit: amigakit.amiga.store/catalog/product_info.php?cPath=39 products_id=615 Only printed parts, hardware NOT included. Will be made with White Abs but i also have black/red/gray if you message me before buying i can make it in one of those colors instead
