Quite well in the games i play actually, Im surprised at how it performs. The only games I've had any issue running are GTA 5 and Rising Storm 2. I definiately wouldnt recommend it for a new build though.
If im being honest, this case is fairly easy to cable in, just making it look good is a concern, i just redid my cabling, and i will post pictures of it shortly, but to answer your questions. This is NOT a full tower case, this is a midtower. It's a fairly large case, but not big enough to cause major space issues. It is 19x8x18 inches (or 500 mm x 223 mm x 475 mm if you dont use freedom units). With you being a first time builder, i would recommend it to you comfortably if you can easily catch on to how to shape wires and stuff, otherwise I'd recommend something like the Phanteks P400 in the same price point.
Pascal doesn't allow more than 2 way SLI, unlike Maxwell, Kepler, and other older chips. Its kind of a better idea imo because more people were actually losing performance, or the performance gain was so negligible with multi card SLI, that it was just impractical. Also, you would've been better off mining with a 1070, or RX 580, on the red side, because of something weird about hashrates decreases and GDDR5X VRAM, but to each their own.
Inb4, i understand having them if they're required for your work, but even then, something like a Quadro or even a Vega FE would've done you better, productivity wise, with them being specialized for workstations
Nonetheless, a single 1080ti would've been ample enough to power both, even in a high load scenario.
Id advise replacing it soon. That PSU isn't exactly the most reliable unit. I've read reviews saying it's failed in under 2 months. I'd hate to see such a nice pc be taken out by some bullcrap psu.
Your power supply makes me cringe, other than that, good build.
I realize im a bit late on the draw on this, but higher end (mechanical, dont pay like 50+ for a membrane) keyboards generally last longer, feel better to type on, and have less latency from keypress to activation. I can't really see a justifiable point for higher end mice though, other than more programmable buttons, higher dpi, and higher quality feel. Just my two cents though, I'll never go back to a membrane after getting my mechanical. Wonderful build, nonetheless.
Where's the I/O shield?

Bravo good sir, bravo.
Here's the thing: I didn't spend a dime on either storage or the OS. And how I got the card was through a couple trades. I was working on an incredibly strict, as well as small budget (~$250), so i didn't see an SSD as priority, nor did i see 8GB of ram in the same light as i did a good PSU and motherboard. I do plan to snag an SSD as soon as I can, as well as jump up to a 16GB kit. Thanks for the comment!
What need do/did you have for the iGPU?
