Hi all,I've been lurking around these forums for some time, I've even posted a handful of times, mostly to try and find answers. It was probably a couple of months ago that I decided that I really needed to downsize my PC.I had always been interested in having a fairly small PC anyway, but I was drawn in by the Corsair 380t marketing without realising just what a behemoth it was. At 40 liters it has to be one of the largest mITX cases out there and it even rivals most mATX. Simply put, it is just too big.However, I wanted to keep as much of my rig as I could. Intel - Core i7-4790K 4.0GHz Quad-Core Processor (£257.84 @ BT Shop) Cooler Master - Nepton 240M 76.0 CFM Liquid CPU Cooler (£99.99 @ Amazon UK)Kingston - HyperX Savage Red 2x8GB Crucial - MX300 750GB 2.5" Solid State Drive (£208.00 @ Amazon UK) Samsung - 850 EVO-Series 1TB 2.5" Solid State Drive (£295.98 @ YoYoTech)So began the quest for a small PC case that could fit all of this hardware. It was a difficult one.Posting on here was some help, people recommended a few cases or changes that I could make. Unfortunately it seemed that the only real suggestion was the NCase M1. Here in the UK the NCase would cost somewhere in the region of £200, and that wasn't even factoring in the additional cost of adding a PSU. No, I wanted to do this as cheaply as I could (mainly cause I didn't have the money to drop on the NCase.Seriously. You don't realise how under served the SFF market is until you really try to find a case that hits all of your criteria without breaking the bank.Eventually I found a case, more by luck than skill.The Sharkoon QB One.It's cheap, it's simple, and more importantly, it's small. At a hair under 15 litres it is less than 2.5 litres bigger than the NCase M1, and it does that at a fifth of the price.Now don't get me wrong, I would love to get an M1, it's a beautiful case, well designed and worth every penny. Unfortunately training as a teacher does not pay well, so I had to do this as a budget, and I was sick of the leviathan that is the 380t.So of course I started researching the QB One. Which is where it became more difficult. This case isn't available in America, which means that there are virtually no reviews or build logs online, in English or otherwise. I found a few, either in the C10 (the QB One's sister) or in the QB One, but none of them answered the question I was asking.Would the Nepton fit?According to the Sharkoon website the answer is no. With fans, the Nepton 240m radiator hits 52mm. The QB One only allows for radiators of 50mm. Eventually I came to the end of my final placement and final assignment. I was tired of getting home and working until dinner, so I decided I would do something else, build a new PC (sort of).I ordered the QB One from Amazon (good old Prime) and this Friday I set about dismantling Ruby (the 380t) and transferring components into this new case.Already it looks so small.The first step was to open up the QB One, and like the SG13, it is pretty much just a frame. There is a power cord included so that the PSU can be mounted at the front, and that is very neatly tidied away and cable tied before sale. That certainly made my life easier.Now when I first built my PC I did so with the help of a friend, and although I had changed the RAM and drives since then, I had never done a full-blown build by myself. That and the whole flat is carpeted, so I was a little nervous. Equipped with an anti-static wrist strap I first removed everything from the 380t. It was relatively simple, big the case may be, but it's lovely to work in.That done, I began to transfer components into the QB One. Oddly enough I had no problems popping the I/O shield into place, it snapped in satisfyingly and without a fight. There will be no baptism of blood for the Black Opal.Clearly not baptising the case was a mistake, my PSU (a Superflower HX750W semi-modular) wouldn't fit! that is the last time I trust Overclockers specifications. I knew I was taking the risk in truth. Superflower themselves listed the PSU as 165mm long, but the 380t should only fit 160mm. Overclockers listed it as 145mm, right on the limit for the QB One. I wagered that Superflower was factoring in the length of the modular connectors as well. I was very wrong.My GPU fits easily, it was a little awkward and involved some contortion to get it in, but I managed it (removing and replacing the RAM to do so). Also, that cable management of the power cable I mentioned? Those cable ties push against the fan blades. A moments work with a pair of scissors and they were short enough that they should cause no issues.After a few false starts where I mixed up screws I added in my 1TB 850 Evo. Fortunately there are screw holes provided on this bracket, but I can't help but wonder why they didn't swivel the placement 90 degrees and allow you to place two SSDs side by side.Cue the next day (thank you Amazon Prime). The SF450 is pricey yes, but I was intending on moving to this PSU in the future anyway. Being able to sell my old PSU should soften the blow somewhat.It fits! Also, damn this PC needs a lot of cables. The absolute minimum I could get by with ended up being all but one of the provided cables with the SF450.My first mistake. In a case this small and tight, that I have already (foolishly) placed the GPU in, it is damn hard to plug in the front panel headers. It's even harder when you have already plugged in the 24pin... And that hole above the power connectors for the GPU, that's just so you can access it. If you route cables through there then the lid of the case won't close properly. I don't have particularly large fingers, but I found it a challenge to route the cables through the tiny hole above the GPU and below that bracket. It might be an idea to plug these in before you put the GPU into the case.A bonus pic taken by my girlfriend (I highly recommend one, small fingers, ideal for the fiddly bits). Please forgive how messy my work space is, normally I'm much tidier, but I got a little over excitedPlease, when you put the faceplate back on, remember to turn the PSU on. It's a pain to take that faceplate off when the whole thing is assembled. Strangely the cable provided by Sharkoon is a little long here. You might have to wiggle it about a smidge to squeeze it in behind the front panel.Adding the Nepton to the case. A little fiddly, but with an extra pair of hands to hold the radiator out of the way it is a lot easier.This is where I faced another challenge. Two in fact.240mm AIOs are big. Really big. So big in fact, that no matter how hard I tried the lid of the case would not shut. The cause of this were the two challenges that I already mentioned. One was that the screws used to attach the fans to the radiator are thumbscrews, these screws increase the depth of the radiator by about 2-3mm. Fortunately I had some screws of the right length and screw thread. That one was easily solved. But still the lid would not shut. The radiator reservoir would catch on the lip of the case. The solution? Unmount the radiator, close the lid, and awkwardly move the radiator about with one hand until you can screw it in from the top.Also, the SF450 SATA connectors are just a fraction too short to make use of the rear SSD mount, and I'd rather have the potential ventilation that offers anyway. Hence our friend the crucial SSD tucked away in the corner there.Also, please forgive me for my awful cable management here. At this point I was exhausted from wrestling with the radiator and the 24pin. I was also very upset when I realised that my tea had been sat unattended for nearly an hour at this point...And now my computer actually fits on my desk!I'm still not set on the shorter orientation, but it looks good and I'm happy to try it out for a while. I can always take the feet off and move them around if I want to experiment.Well there it is. The first build log I have ever written. I apologise for the quality of the pictures, but it was my first time.
