    Hi all, new to the form and figured I would share my build before I start asking for help!

    I absolutely had to have the SG13, but I was on a very strict budged and didn't have $ left over for AIO or a fancy high power SFX PSU, So I got the best deals I could on all my components and didn't like to stock layout of the SG13, so I modified it to how I saw fit, and this is the outcome!

    I currently only have a 275GB M.2 mounted under the motherboard, I have a 1TB Samsung F3 that I plan to install in the front cover of the case after printing an extender for it. I also have 2 80mm fans on order that I will be mounting to the rear of the system with a pantyhoe filter. But thats a couple days down the road.

    Case: SilverStone SG13B-Q
    Motherboard: ASRock AB350 Gaming-ITX
    CPU: R7 1700 With Stock Wraith Cooler
    Memory: Patriot Viper 4 16GB 3200mhz
    Video Card: Power Color Red Devil RX580 8GB
    SSD: Crucial MX300 M.2 2280 275GB
    HDD: Samsung F3 1TB
    PSU: Corsair CX550M

    Great work. You've gone and done it! I had an SFX front mount PSU in mind for a while, but haven't got round to doing it...there is a thread about it on here somewhere.
    I have an SG05, SG06 and SG13 so am sold on these little gems. I do like the 'Q' front panel, which suits this sort of build perfectly. I prefer it to the standard front. My SG13(W) was used, so I had no choice; the gaming rig would overheat in a Q I think.
    I had imagined that I'd use a large top-down cooler and a 140mm fan at the top of the case blowing down over the board.
    Maybe one day.

    Thanks! I'm really enjoying the build so far, its nice to get to build something like this.

    I built a I5 4460 system back in 2014 with the SG05 and as soon as I saw that case I was hooked on SFF. I had been stuck with a 2500K in a Corsair 230T since 2011, that processor aged amazingly! it still handled everything I threw at it, but I got a smoking good deal on the R7 1700 and just had to build an ITX system!

    Ya, the Q version would probably be a little low on airflow if the front was an intake for the system. AIO or air, just not enough ventilation I think, and in the stock configuration the PSU would cover all the upper ventilation as well.

    I was originally looking to get a SFX PSU and still front mount that, just differently, that would have left me with so much room I wouldn't know what to do, but when i was looking to buy I couldn't find any in my price range. So I went ahead and decided to make a full size PSU work, its definitely getting tight in there! I thought about mounting the PSU fan facing the motherboard, but then I realized that as I start to plug in all the cables it would start to block the airflow, and some PSU don't run their cooling fans below a certain temp. So I went with the front facing and we will see how it does!

    I still plan on extending my front cover so I can use the USB and audio plugs, because I would use then all the time, and this board has fewer USB plugs than I am used to.

    I might extend the cover as a whole so I can shove my 1TB drive in there and leave maximum room for cooling, but I have managed to stick it in a pretty ok place at the moment. It blocks about 2/3 of the top vents which I don't care for. But I had to stick it in there somewhere so I had access to all my 3d printing stuff

    I'm also seriously thinking about either cutting out a section of my PSU cables, or re-pinning them so i have shorter cables, that would make the upper section a lot cleaner and give me back just a little bit more room. Although, I do enjoy warranties as I have used them a time or 3. . . .

    Currently using a book to level out my case, printed stands in the next few days.

    Anyways hope enjoy the pics, and maybe you will mod your own!

    i managed to get a lot done this weekend.

    Printed some feet to keep the case from resting on the PSU cord, which also allowed me to retire my handy leveling book.

    I purchased some thin Cooler Master 80mm fans, I test fit them with a temporary mount and found some additional clearing that needed to be done. After verifying that everything would fit after some bending I designed and printed a proper fan shroud. I also found that one motherboard header can control a 3 pin fan, where the other is PWM only so its always full speed.

    I spliced the 2 fans together so they would both run off of the same motherboard header that allowed speed control. I thought about ordering a Y connector, but decided to just cut it! I think it came out a little cleaner that way, but I left WAY too much heat-shrink on the connector end of the cable assembly. I might clean that up later down the road. At first I installed the fan to the wrong header, so the last set of pictures are the correct header.

    Now I need to figure out what I want to do with the front of the case, extend it to fit my HDD and USB headers, or do something else.

    Thanks, I'm having a blast with the build.

    Looking at some of your projects I really need to use a proper camera and clean up my area, lol! Nice builds and great camera work!

    Got a new toy! Noctua NF-F12 3000rpm.

    I'm going to play with it a little, but I think this is going to be my new heat-sink fan.

    It currently wont fit at all, even if I rotate the HDD sideways, so I have started drawing a new front cover for the case that will accept the 3.5" drive. I have been playing with the idea of making it hot swap-able but I'm not sure yet.

    My thoughts are currently remove the stock fan on the heat-sink, build a mount that will place the F12 at the top of the case so it has access to fresh air, then print a funnel to guide the fresh air to the heat-sink.

    I plan to test both airflow directions. Some people have said sucking hot air off the HS lowered all temps including VRM so I figure its worth a test to see what happens in my case.

    I think I have a design that I'm comfortable with.

    I moved the USB and audio ports to the top, it seemed like the best place to put them with everything else going on in there. It should use the original power and reset switch assembly, I might have to print a new power button cap but we will see. There are a couple points for cable management.

    The cover has been extended approximately .625" to accommodate the hard drive, as much that I would like to ditch it I need the storage and cant afford a large SSD.

    I added some ventilation to the front of the cover right where the video card sits, there's space for either 4 40mm fans, or 2 60mm fans with a max depth of 20mm. I also might toss in some red LED's to add a little character. There are no mounting points in the cover for the fans, I will make a separate fan cage to hold everything if I think I need them.

    Please excuse the very amateur renderings, I have absolutely no experience with Keyshot or any rendering programs.

    There are a couple of overhangs, but my bridging is pretty good so we will see how it works out.

    Got the front cover printed. It looks pretty good, but it has some issues so I opted to not finish it with paint and a good sanding. I will make some adjustments here and there and make another. Plus it looks much better in person, the camera brings out all the little details you wouldn't otherwise see. The power button didn't fit like I had hoped, but its out now so I can model the switch itself and make the next one work.

    The hard drive area has little tabs that lock the drive into place without the need for screw. I did have to do some trimming on the front of the metal case because it was protruding into the HDD circuit board.

    A little hot glue here and there was used to secure the existing LED to the side of the vent, It was also used here and there to help with cable management. The rats nest on top was re-organized in an attempt to clean it up a little bit.

    Overall it looks pretty neat and I'm quite happy with the results so far. Now I can start designing the CPU fan mount and supporting pieces.
