I wanted to share my experience building my Node 202 with everyone. I actually built this PC up twice, first with the stock Integra PSU (made by FSP), and the second time with a Corsair SF450. I'll post pictures of the internals with both so you can see the difference/potential cable management with each. I've also seen some people go with SFX-L sized PSUs, but I can't recommend doing so as from what I've heard this requires removing the SSD bracket and leaves very little room for cable management.
Here's an album of the build in case Imgur is easier for anyone.
Building the Damn Thing
So, first let me say that it's really important to plan things out with a mITX build like this. I went in the first time thinking it would be pretty easy/straight forward, and boy was I wrong. While I was able to get everything together I had a few issues caused by not planning ahead. The biggest issue was that I forgot to connect the USB 3.0 header to the motherboard before mounting the CPU cooler, and damaged one of the pins trying to get it in without removing the CPU cooler first. I may attempt to desolder the damaged pin and replace it at a later date, but for now I don't have any need to.
As I hinted at before, working with the Integra PSU eventually led me to switch it out for a Corsair SF450 for two reasons: cable management and noise. The potential to get your cables neat and out of the way with the SF450 is much greater than with the Integra, and the Corsair is a little quieter overall. I managed to pick up the SF450 for $75 from eBay (via Newegg) the last time eBay had a $15 off coupon.
While the cables for the SF450 are fairly stiff, they aren't nearly as stiff and bulky as the ones on the Integra, and they were much easier to bend and get into different positions. They're also very flat, which allows you to easily route the cables through some of the other components to get them hidden better.
I was able to route the CPU power cable and the system fan/CPU fan cables between the two sticks of RAM, freeing up a good amount of space between the PSU and the motherboard. I was also able to route the USB 3.0 cable and audio cable through the GPU bracket and riser, leaving some empty space between the motherboard and the wall of the GPU compartment. Lastly, I was able to tuck the SATA and SATA power cables into the extra space in the SSD bracket.
For the bulky 24-pin connector cables, I did my best to loop them and compress them in a couple spots with zip ties, then used a zip tie to secure the bundle to the bottom of the case.
For this build I went with an i5-6600K and Asus GTX 1060 6GB Turbo. My total cost for the build (not including the monitor) was $1175 (including both PSUs). I was able to get an excellent price on the CPU ($185), motherboard ($125) and M.2 SSD ($140) at Micro Center, which brought them to about $70 less than what I could have got them for online, even though I paid tax at Micro Center and wouldn't have online at the stores I was looking at (Newegg, SuperBiz & OutletPC).
As for cooling, I went with the Scythe Big Shuriken 2 Rev B. At 58mm it's just outside the supposed CPU cooler height limit, but it fits just fine. I've heard of some people having issues with other varients of the Big Shuriken, and I could imagine that if your motherboard sat a tiny bit taller in the case then even this one wouldn't fit. From what I've seen the Big Shuriken 2 Rev B is probably the best CPU cooler that will fit in the Node 202. For case fans, I went with two Fractal Design HP-12 PWM fans. I strongly considered getting some Corsair or Noctua fans instead, but the HP-12s fit the look of the case quite well and had good reviews. They perform great as well, and are quieter than the GPU or the CPU cooler, so the amount of noise they add is pretty negligible.
Performance and Temperatures
So far this PC is performing beautifully. I have my CPU overclocked to 4.5GHz using a positive dynamic voltage offset (can't remember the specific offset, but I think +0.09 sounds right) and enabling all power-saving features. I'll probably try fine tuning it a little more later, but for now it's very stable (haven't had a single issue related to the CPU during normal use, stress testing, benchmarking or gaming).
My GPU is also slightly overclocked using MSI Afterburner. The base clock is bumped up to 1725MHz, a 219MHz increase, or around 15%. My GPU memory clock is also bumped up to 8600MHz from 8008MHz. I have a +5 offset for Core Voltage and power limit set to 102.
As for temperatures, my CPU is usually under 30C during light tasks (Chrome, Office, etc) and my GPU hovers around 30C, but tends to get up to 32C after the computer has been on for a while.
During stress testing my CPU will get up to about 70C (aida64, x264), but I've never actually been able to get it that high doing anything else. During gaming the CPU has ranged from 40-65C, depending on the game. On the other hand, stress testing and benchmarking hasn't stressed the GPU as much as gaming does (probably due in part to how long I'm gaming for vs how long a benchmark runs). Most benchmarks get the GPU to the low 70s, and aida64 only brought it to the low 60s, while games like Witcher 3 and Doom (both at 1440p/Ultra) bring the GPU up to about 76.
