Introduction Hi Bit-Tech Modders! This is my second case mod and my first scratch-build case. Its is also my fist worklog, but hopefully all will go well anyway Ive been watching the Bit-Tech forums for a few months and its a great place for inspiration, and what has motivated me to start this project. The name for this project comes from the position of the motherboard tray, it is tilted at a 30degree angle. Not a very inventive name i know, but ive been unable to think up a better one so it will have to do. I hope the log will be easy to follow, i will do my best Any advice is always welcome and if you have any questions i will try my best to answer them List of Project Updates: ► Update 1: Building the Frame - 21st September 2009 ► Update 2: Fitting the Motherboard Tray and Horizontal Panels - 27th September 2009 ► Update 3: Hinge and Vertical Panels - 20th October 2009 ► Update 4: Making the Back Plate - 4th November 2009 ► Update 5: Cutouts and Mounts - 14th November 2009 ► Update 6: Feet, Fan Controllers, and Front Connectors - 10th December 2009 Design and Layout The basic layout for the case is to have the power supply, hard drives, and cd/dvd drive a lower compartment of the case. The motherboard will be located above these in the upper compartment tilted forward at an angle of 30degrees. The components will be air-cooled so the case is designed with that in mind. The footprint (is that the right word? ) is a 40x40cm square, the case will be taller at the back than the front and the top/roof will curve down. The top is going to be placed on hindges to allow it to be lifted up easily, giving quick access to the motherboad tray. Airflow for the case will be more-or-less the standard front to back. The top of the case will be made of mesh to provide additional ventilation. The main framework will be made up of 25x25mm aluminium square-bar and plastic connector pieces. To this will be fitted the sides, made from 1.5mm aluminium sheet, as well as any other parts. I listed the mod as a scratch build, although i am using a lian-li motherboard tray, but i thought 'scratch build' would be the best lable to give it (please correct me if im wrong). The following drawings were created in SketchUp and are probably the best way for me to show the layout im going for in more detail: Light Grey = Aluminium Black = Plastic Green/Blue = Fans Purple = Mesh Dark Grey = Components Orange = Lights/Displays (Note: the sides will be covered by either aluminium sheet or mesh, but a lot of it has been left out of the design in SketchUp) Design Pic 1: Here you can see the case front. The intake fans will also have some mesh covering them, but i left it out of the pic so that the fans are visable. I will be using vandal-resistant switches, 22mm ring-led for the power and power led, and a 16mm dot-led for the reset and hdd led. I did consider using a slot-loading drive but i didnt want to risk scratching discs due to a poor finish on the slot, ive very little experience working with aluminium, so i though it best to go with a traditional style drive. I will swap the activity led to a different colour though, so that it fits the theme of the case. There is an LCD display on the top of the case. I was thinking of using a Matrix Orbiatal display or something but im not sure. Design Pic 2: This is the design shown from the back. There are 3 switches used for the CCFL Lights; the first will control a white cathode at the rear of the case used to illuminate the ports on the back of the motherboard (i always have difficulty plugging the things in so i though this would be a good inclusion to the design! ), the second switch will control 2 coloured cathodes inside the top compartment of the case used to light up the motherboard, the final switch will control 4 smaller cathodes located under the case which will hopefully provide a nice glow when the comp is in a dark room. The 2 different designs for the handles can be seen on the sides of the case in this pic and the previous one. I think i will go with the first, straight, design as the cuved one is a little large for my liking. I placed the fan controllers at the back of the case because i likly wont be changing the fan speeds that much, and in this location they will be out of the way, but they are still there if i ever feel like i need a little more cooling (or less noise ). Design Pic 3: Well, theres not much i can say about this pic, only what is already annotated. Design Pic 4: Here the top of the case has been removed and so have the front fans too, to alow the insides to be seen. 1 of the temperature displays will be used for the lower compartment, and one for the upper. Here you can see the cathodes on the inside of the case, they have a piece of aluminium covering them at the top so that im not blinded when i open up the lid! xD The fans on the sides are angled to direct the airflow onto the motherboard. I came up with 2 ideas for how to do this which are shown in the pic, the main difference with wether the fan is attached diectly to the case side with a duct on the fan, or if the mount is angled and attached to the case on one side with the fan on the other. Design Pic 5: This pic gives a nice view of the motherboard tray. The white cathode is shown too, which will also have a cover over the top to help direct the light down and stop it just shining into my eyes. Design Pic 6: Shown here are 4 hard drives (2 in each rack/mount). They will be cooled using 2 92mm exhaust fans. Other than these 2 fans and the one on the PSU there will be no other cooling in the lower section of the case, although there is a large mesh vent at the front to allow cool air to get in (and space there to add some more fans later if aditional cooling is needed). Design Pic 7: Here are some very basic views of what the outside of the case will look like, its not very accurate but i was only really using it to test colours. I wanted a dark colour for the main body, at first i thought black, but black is quite common so perhaps a dark graphite/charcoal/gunmetal colour as used in the pic would be a better alternative. To go with this dark colour i wanted something a bit brighter for the lights and mesh, to contrast. At the moment im leaning towards the orange, but im still not really sure. Somthing about the orange just seems to jump out at me though. I will (probably) go with a 2-tone (is that what they call it? ) colour scheme, but i may well end up going with black for the framework. For the finish im thinking a satin powdercoat, but thats a long way off so no need to make a decision about it now, although i would like to go with a powercoat.
