Constraints
^{of the related project}

This manual's sole purpose is educational, owing to the peculiar constraints adopted:

extreme budget management, but no any particular time limit

commercial available hardware components assembly, only

no mechanical nor electrics mods allowed but 3D printing

a chronological try-and-error learn-by-doing approach

non commercial and non derivative license terms.

The choice of Esprimo P910 is part of the challenge, not the most suitable platform.

   ·NOTICE·  

Those mechanical add-ons included in this manual, despite being initially hand-crafted, will not be explained for replication, but presented as an R&D-like exploration toward an appropriate solution and as propaedeutic pre-3D-printing prototypes. The Latin prefix "pre-" here means that 3D-printing is considered part of the "Production".

   WARNING!  

In case a non-reversible change will be presented, in the aim to provide myself a long-term functioning prototype useful to further develop this manual - the other half about the software installation and a use case - the risks related to that change will be presented in the manual, as well. And among others viable alternatives, one for the professional-driven modding shops and the other for large scale industry, will be suggested at least.

Introduction
^{written by DeepSeek 3}

This manual is your ultimate guide to installing a Nvidia Tesla K80 — a powerful dual-GPU accelerator — into a Fujitsu Esprimo P910 E85+ desktop computer. Designed for those who love a good hardware challenge, this document walks you through the process of adapting high-performance server-grade hardware for use in a non-standard desktop environment. The author also discusses the use of a secondary power supply unit (PSU) to meet the power demands of the Tesla K80and explores cooling solutions to manage the heat generated by the GPU.

Parts List (BoM) - A detailed bill of materials (BoM) is provided, listing all components used in the project, including their costs and sources. This section also includes a list of consumables and tools used during the project.

Fujitsu P910 E85+ BIOS Update & Diagnostics - This section explains how to create a bootable USB stick with FreeDOS for updating the BIOS and running diagnostic tools on the Fujitsu Esprimo P910. It includes step-by-step instructions and links to necessary files.

Tesla K80 with Esprimo P910 - The author details the process of installing the Tesla K80 into the Fujitsu Esprimo P910, focusing on the challenges of fitting the card into the case, providing enough power, and managing thermal issues.

Dual PSU for Fujitsu Esprimo P910 - This section explores the installation of a secondary power supply unit (PSU) to power the Tesla K80. It discusses the technical details of grounding, synchronization, and cabling, as well as the challenges of fitting the PSU into the DVD bay.

Dual PSU Esprimo P910 Installation - This article continues the discussion of the dual-PSU setup, focusing on the installation process, venting system modifications, and the challenges of cooling the Tesla K80 in a non-standard desktop case.

External Sources - The document references external resources, including guides on power limiting GPUs, videos on 1U PSU units, and cooling solutions for the Tesla K80. These resources provide additional context and support for the project.

Parts list (BoM)

The bill of material with the price paid on the consumer market, including the cost of expedition.

The following is the list of material consumed or wasted, which contributed to the product unit cost.

As you can imagine noticing the contrast with the first table, this above is just for the sake of professionalism. And for the sake of completeness, I would also add the list of the tools used and their amortisation as middle-term consumable assets. I hope you will excuse me for not complying with this best practice, in this case...

This "Linux Thinkpad e altri gadget" (PDF) written in Italian can be helpful to setup a low-cost and Linux-friendly 3D printing home-lab, starting from zero, as well. Undisputedly, a completely dedicated 3D-printing lab is not the ideal resource allocation for many, therefore "from zero" means "from the beginning".
