'Stealthing' the Motherboard
Way back when I was planning and visualising the case, I realised I would need to do something about the motherboard. There seemed little point in modding all these internal components only to mess it up with a raw ugly PCB dominating the case. Also, with the amount of steel hoses used in the project, there was a very real risk of accidental contact shorting it out. To deal with both problems I came up with the idea to 'stealth' both the motherboard and PCI cards by fabricating covers out of acrylic which I would then later get chromed. Why acrylic and not metal? Well, I had the material handy, I was used to working with it and I could bend it a lot easier using a heatgun etc than I could bend, say, aluminium without owning a bending brake; and for what I had in mind, I needed the straightest, most accurate bends I could get!
The whole 'covers' concept was something that had to be incorporated from the beginning, with test-fitting and mock-ups tried out in the case every step of the way. I had to consider many factors including: heat, airflow, cable interface, electrical insulation, looks, practicalities and fitting it all in! Fortunately, having a totally water-cooled system was going to make things a whole lot easier. I did tackle both the PCI cards cover and the motherboard cover simultaneously, but I'll start with the motherboard first. This is what I ended up with:
The motherboard cover from the front. All the shower hoses carrying the wiring screw into threaded fittings. From L-R: Serial for VFD; 12vP4 (top); 9800Pro/1 x SATA HDD Power (below); ATX Power (split into 2 cables).
There are openings for the watercooling hoses, a vent over the RAM and the whole cover is open at the top and bottom to allow some airflow. The back of the motherboard is concealed by a polished chrome panel.
It's all very shiny! One of the cool things about chrome covers is how they reflect like a mirror. In this project they create an illusion that there are more cables and hoses that there really are (though there are still a lot!). Plus the chrome reflects any lights and glowing panels inside the case. Anyway, here's how I did it...
Making the Front Cover
I started right back in the planning stages by making up cardboard models...
...and test fitting. I would add and remove sections of the model, using masking tape to attach the added pieces. Of course, it had to fit with the drives and PCI cards installed!
I even made a model out of a thin plastic sheet. Hole positions and lining up with sockets on the motherboard were critical. I'll do a 'fast-forward-in-time-oops-I-lost-one-of-my-photo-disks-how-embarrasing'...(well, it was nearly a year ago)...
...and on to the cover itself. This was ruled up, cut out using a hacksaw, holesaws and step drill. I folded the ends by clamping the piece using planks of wood and heating with a heatgun. The same techniques I used in previous articles. For an in-depth guide on working with and shaping acrylics, take a look at some of the work by
eddie the dane and
Linear plus other modding articles featured on bit-tech.net. I drew on these as the basis for most of the acrylic fabrication techniques used in this project.
Even by hand, it's still possible to get nice, sharp bends!
