The new motherboard must seamlessly fit PCIe slot #2 on the HP Z800 series workstation, encompassing models like Z820 and Z840 as well. For optimal printing results, it's recommended that you use a piecemeal assembly process for easier setup and management. When building, carefully weld each component together using superglue; supplementary support may be required where necessary, which can be effectively secured with duct tape. Furthermore, due to design specifications, this particular system requires unrestricted airflow in order to operate within normal temperature ranges; hence, removing the side panel of Z800 workstation while in use is likely a good practice to ensure smooth fan operation and adequate cooling.
