Bunch of random thoughts below, you should probably skip and just look at the pictures.
Ran across the In Win 904 months ago and absolutely fell in love with the case. Pretty much convinced me to build my first PC. I knew a little bit about SSDs and swapping out components on prebuilts, but no knowledge about PC building beyond that. Researched like crazy and read everything on /r/buildapc for about a month before pulling the trigger. PcPartPicker is such an amazing resource (and time suck, hmm let's compare i5, i7, and x99 builds...)
Not sure if prices on the left are accurate to what I purchased but yeah I could have cut down some costs along the way.
CPU - Pretty standard and more than adequate for my purposes. Been playing around with overclocks, but coming to the realization I'd rather have less fan noise than faster clock speeds.
RAM - Another standard choice.
Storage - OS (Windows 10 TP) on the 850 EVO. Backup on the OCZ Arc (TBH I got it to match the rest of the build, and it was on sale). Videos on the WD. Went with the 5400rpm Green because I wanted to reduce noise (vs a 7200rpm drive). 4tb is kind of excessive, but wanted space for the future. Plus I can't be the only one that rips blu rays uncompressed... Thinking about getting another in the future for RAID 1.
GPU - I only play LOL on my single 1080p 60hz monitor. Pretty sure the 960 is overkill already. Sadly I don't know since the latest LOL Patch 5.5 is incompatible with Windows 10 TP, so haven't had a chance to play. Thought about a XFX 280/290 DD, but wanted to keep heat down.
Motherboard - Works fine. Would have better if it had more than 2 fan headers and if it had right angle SATA headers, but I guess that's the tradeoff for the mitx size. Also wish there were some good resources for Asrock UEFI Overclocking.
Case and PSU gave me so many headaches:
Case - I love the look of the In Win 904. In Win recently came out with a 904 Plus, but it only comes in Black and Red. Main difference is the 904 barely supports a 160mm PSU, while the PLUS version supports 180mm. I emailed In Win and they said the Plus in Silver wouldn't be available until like September 2015. I didn't want to wait that long and was trying to avoid red in my build. After deciding to go with the original 904, I couldn't find any place that didn't sell it bundled with a PSU. Went ahead and paid extra for the 904 bundled with a PSU. A couple of weeks before, I had built a mitx for my parents (basically a training exercise). So no experience with Mid Towers. I unpackaged the 904 and thought it was obscenely large. Loved the look, the proportions, but it was just way to large for my desk. Strange how I never noticed how large Mid Towers are even after looking at hundreds of Build Completes. Went ahead and exchanged the 904 for the 901 (smaller, mitx version).
PSU - I wanted to purchase sleeved cables, and only found Corsair and EVGA made them (couldn't find cables for Super Flower or Seasonic - the other high end PSUs). But couldn't find EVGA cables in stock on Amazon or Newegg. With the 904 case, I needed a PSU 160mm or shorter. Went with the AX760 (even though it broke the color theme). Once I switched to the 901 (smaller case, but actually has a larger PSU slot), I was going to switch to the HX750i (color again), but it was out of stock, so that's how's I ended up with a HX850i. Complete overkill for my 70-300W build. On the plus side, the fan never comes on. However, I'm definitely below peak efficiency.
CPU Cooler - Case isn't that wide so couldn't use the Hyper Evo 212. Like the look of AIO Coolers, but didn't realize I'd be able to hear them. The 901 could really use an exhaust port larger than 90mm. I would have preferred the Nzxt Kraken X31, but couldn't find it in stock anywhere. So went with H60. Most sane people mount the AIO outside of the case, but I really didn't like that look, so I jammed it into the gap at the rear of the case. The piping is pushing it back out so hard that it's just jammed in the gap, so I didn't even screw the radiator fan combo onto anything. 120mm also barely fits, as it presses against my ethernet cable.
Cable Management - I tried my best, but it's a small case. I now realize if you're really OCD about it, you need to sleeve your own. The sleeved cable kit I bought was way too long for my case. Also most cables are daisy chained for convenience, but that just adds extra connectors that you might not need.
The fans are really bugging me. Mobo only has two PWN Fan Headers. H60 AIO needs one for the pump. That leaves one fan header for the intake fan and the radiator / exhaust fan. I used a splitter, but have to set fan curve in the BIOS, otherwise they just blow at 100%.
