Hi Me and modding: I created my 1st mod and water cooling solution 26 years ago and this will be my 1st scratch build. Lets just say I'm motivated to get it right. The Planning stage! The cook book! My recipe for scratch building. Expectations, Purpose, Hardware, Design and a load of details! Expectations: Not a theme build unless minimalism counts as a theme. Low weight so its easy to transport. Time until its ready 12 - 16 months depending on imagination, resources and materials. Easy access to all components with a minimum of screws and bolts.Not yet fully matured its version 1. The case build is modular. Purpose: This enclosure will be made for a PC that will be moved relatively often. It’s not an open case design, because of the risks to the components. Its main purpose is to hold data that is in use on weekly basis, for long time data storage there is a NAS available. The design is chosen to be easy to upgrade, long term reusable (12-15 years thinking green maybe?) and for maximum flexibility in daily use. The PC’s hardware components are chosen to be all round capable as a gaming PC and a Work station for data recovery, rendering and video editing, flexibility being the key word. Hardware: The enclosure has to accommodate an ATX sized motherboard, the reason being the flexibility on a board of this size when adding other components. For virtualization of several RTOS on this one system, there has to be room for more than 1 GPU and an additional USB card. The case will be large enough for two full sized GPU’s 340 (L) mm by 150 (W) mm by 60 mm (H). Available space for radiators is a minimum 2*240 mm (in reality more like 2*290mm). The PSU can also be 230 mm in length with space for cables. NO RGB components unless my nephews force me with their built-in persistence. I am still researching materials, production methods and tools for the job and since I have next to no experience with scratch builds, especially not at this level, I have read a lot and watched a lot of videos on YouTube - I will add a list of my favorites. Design: Simplify design bring down complexity and then try to make it better. This is where I start.
