Intro So I've been in China for the past 3 months, and I've determined that my old Asus G37 laptop just isn't cutting it any more. I'm still in the middle of a massive server rack desktop build which is now on hold due to the business trip, but I obviously cant take that beast overseas with me. I've been spoiled by my (multiple) Gen 3/4 i7 desktops at home, so I need a portable solution that can keep up. There's no way to upgrade the G37, and new laptops are bloody expensive. So I've decided to build the smallest full ATX i7-5930K system that I can, complete with portable monitor and keyboard. No corner-cutting here, this little guy will sport an i7-5820k with 32GB DDR4 RAM (upgradable to 128GB) and a GTX-780. Because there's no reason for me to build a portable computer if I can't add it to my render farm when I'm not porting it. I've got 2 weeks to get parts and build this thing, so emphasis will be on funcationality rather than aesthetics. It needs to be rugged with all components firmly mounted, and fit the size requirements of a carry-on (preferably smaller, just in case). This is a hard deadline, as I have a return trip to China that will last another 5 months . . . and bringing tools / buying parts over there just isn't an option for my hotel room. Since I've had one request already, I plan to post a full parts list and build instructions when I complete this in case anyone else wants to give it a try. I've focused on components and parts that require the least amount of cutting or custom work for the purpose of assembly speed. If anyone wants to take the design and turn it in to something beautiful please feel free. I may even tackle this myself at some point. Oh, and I'll also let you know how TSA reacts. Concept Should be mostly self-explanitory. Mocked this up in Blender based on dimensions I found online. Waited until I had some parts in hand to start cutting metal. I'm working in aluminum extrusion again because it's quick to assemble and sturdy. A bit heavy and expensive though. Carry-on Luggage Sizes: - 20"L x 17" W x 9" H - Typically the largest allowable carry-on size. Varies a bit by airline, but this is a good starting point. - 17"L x 14" W x 8" H - Minimum size of under-seat storage. They're usually a bit lenient on the length, but I have no interest in gate-checking a computer. In a pinch the following plans should fit under your seat. Test Fitting I'm still waiting on some fasteners from McMaster-Carr before I can assemble the frame but in the meantime I thought I'd check to make sure all the components fit. AsRock X99 MB and GeChick Portable 15" monitor GPU, PSU, and HDD all seem to fit OK. Keyboard may be a bit of a problem. It's 1.5" wider than I expected, and the USB cable is going to get in the way of the hinge. I think I can work around this, but it's going to add some steps.
