[NOTE: Updated/alternate designs are now included later in thread...] Fellow Modders: I am currently planning my first real mod, which will basically be a scratch build. My goal for this build is to make a fairly compact computer that can fit on top our family computer desk, minimizing the room that it takes. On top of our desk, I have experimented with placing the computer behind the monitor, but it is inconvenient to get to the disk drives, power button, USB ports, etc. I do like having the computer perpendicular to and to the side of the monitor (which is the current position and probably most common everywhere), but there really isn’t any useable room in front of the computer, so it is somewhat of a space killer. For basic design, I want to keep an ATX formfactor, as I think it is more flexible and upgradeable (and I already have older parts that I plan to reuse). I also want to use the rotated motherboard design (think SilverStone Raven cases). Thus, after brainstorming for a while, I decided to experiment by building an L-shaped computer that will also act as a monitor stand, with the optical drives, ports, and power button all in the front, under the monitor. I haven’t decided in the monitor would be attached to the case, or just rest on the “shelf.” In many ways this is similar to an all-in-one, but better (upgradeable) in my opinion. My current concept: My thought process is that with this shape, the computer will be less obtrusive, have a smaller desk footprint (when combined with the monitor), provide easy access to optical drives/USB/etc, hold the monitor, and still be a full-size rig (probably comparable to a mid-tower). Here are some more concept images. And the potential airflow: After thinking about it for a couple months, it finally dawned on me that I can’t be the only person who has ever thought of this. After some fruitless Google searches, I finally found the right search terms and found a company that made an “L-shaped PC case” which is pretty close to what I had envisioned. (http://www.pcgameshardware.com/aid,667031/Chieftec-introduces-L-shaped-PC-case/News/ ) Their case had two main criticisms: airflow and cable management. I think that the vertical motherboard design will take care of most of the cable management issues, and also help with airflow. I also think that adding the fans at the bottom and top of the case will move the air nicely. For now I will stick with air cooling, as I don’t have the money or experience to run water cooling yet. Please share your expertise with me and let me know your thoughts and potential tweaks to this design. I probably won’t be able to build it until October (as I am travelling for work this summer).
