  • 6 for external shroud (8mm long)
  • 4 for motherboard (5mm long)
  • 4 for PSU (8mm long)
  • 1 for GPU hold (5mm long)
  • 2 for USB ports (5mm)
  • 2 for front fan panel (5mm)
• 12 magnets (3x10mm)
• PCIe riser cable 180 degrees both connectors and 185-190mm long(could be smaller but i just have a the mentioned), I designed around this [https://es.aliexpress.com/item/1005006000973971.html?spm=a2g0o.order_list.order_list_main.5.2bd2194dgvI5wu&gatewayAdapt=glo2esp](https://es.aliexpress.com/item/1005006000973971.html?spm=a2g0o.order_list.order_list_main.5.2bd2194dgvI5wu&gatewayAdapt=glo2esp)

• Power led switch button 60cm cable and 19mm diameter. For better fit, weld some different cables or use a low profile button, just needs to be 19mm diameter. [https://es.aliexpress.com/item/1005005585121134.html?spm=a2g0o.order_list.order_list_main.189.2bd2194dgvI5wu&gatewayAdapt=glo2esp](https://es.aliexpress.com/item/1005005585121134.html?spm=a2g0o.order_list.order_list_main.189.2bd2194dgvI5wu&gatewayAdapt=glo2esp)
• 1x 120mm fan, can fit normal 25mm width
• CPU cooler up to 30 mm height, ID-cooling IS-30 is what I use.
