Author's note: The bad cable management most people are commenting on is actually just the CPU cooler cables that I couldn't find anything to do with. The area right next to the PSU is also pretty bad, but overall it's nowhere near as bad as most people seem to think it is. Just sayin'.

Ladies and gentlemen, let me begin by saying that the inevitable detractors and naysayers are right: This PC should not exist. I should have been content with a $2-3 grand build at the most. There, I said it, you win, now you don't have to comment it.
With that out of the way, a bit of exposition and some part choice breakdowns:
This is, as of now, both the most powerful and the most expensive build ever completed on PC Part Picker. It was built to run games at 4K, at framerates that most people would expect at 1080p. And it delivers. Neither Crysis 3, Battlefield 4, nor Arma III can bring it down. The bleeding-edge visuals, combined with some of the best audio currently available (that will get even better once Schiit finally launches Yggdrasil -GRR-), make for a gaming experience almost impossible to rival. Contributing to this machine's absolute dominance are a watercooled CPU and quad-GPU graphics array, 32 GB of some of the fastest RAM this side of Avexir, 2.5 TB of internal storage, and an external summit-fi audio setup. I intend to start upgrades shortly after there becomes something to upgrade to.
Intel Core i7 3960X Extreme Edition: At the time I acquired it, this was the most powerful CPU on the market. It's been passed up by the 4960X by now, but it remains a beast of a processor that's easily overclocked to over a gigahertz above it's nominal boost clock, and can handle anything I throw at it.
NZXT Kraken X40: Despite how into PC gaming I am, I have never actually set up my own custom-loop water cooling system. I considered it when planning what would eventually become this rig, but in the end I decided that one of the most expensive PCs on the internet wasn't the right setup to mess around with watercooling for the first time. The Kraken X40 was particularly great because it has a 140mm fan instead of a 120mm one, meaning that I didn't have to change cases to find one with a third 120mm fan mount when I got the 295s.
ASUS Rampage IV Extreme: I have used ASRock, Gigabyte, EVGA, Intel and other ASUS boards throughout my fantastical voyages through PC DIY, and this is hands-down the best one I've tried so far. Overclocking is hilariously easy, the graphical BIOS in particular is wonderful, and it has 4 full PCIe lanes and 8 memory slots to handle whatever I throw at it in the future. This will probably be the motherboard I use until I'm done with building PCs (not very likely) or I have to upgrade because of a new PCIe/LGA/SATA/DDR standard (much more likely).
G.Skill Ripjaws X 2400MHz: I do a lot of video editing, and so having a lot of RAM is incredibly useful. If this were just a gaming rig, I would have gone with only 8-16 GB. I chose this RAM in particular because of its fast clock rates and timings (that the rest of my PC can actually keep up with). It only gets 3 stars despite its mostly-fantastic performance because one module failed shortly after my warranty expired.
Samsung 840 EVO: This was actually the last thing I bought. I needed an SSD boot disk for faster startup and application launch speeds, and I had had great luck with the EVO line in my other computers so I decided to stick with it. So far it is functioning great.
WD Caviar Blacks: They're big, fast, reliable HDDs. Need I say more?
ASUS Radeon R9 295X2: In my opinion, the best gaming card currently on the market. Yes, I know about TITAN Z. 8 GB of VRAM on dual-channel 512-bit memory busses to handle whatever 4K can throw at them, 2 fully-unlocked Hawaii GPUs on each card at higher clock rates than the normal cards and closed-loop 120mm water cooling (so it's only dual-slot and really quiet!) all make these the obvious choice to me. I went with the ASUS variant because they're all identical so why not. I went with two of them because the benchmarks for one of them at 4K weren't fast enough.
NZXT Phantom 820: It's a big, spacious chassis with neat lighting, tons of mounting points for water-cooling blocks, and tons of room behind the motherboard tray for cable management. The integrated fan controller is great, and it all runs quiet enough on low fan settings that I can't hear it through open-back headphones.
Corsair AX1500i: I've always used Corsair PSUs ever since my last Seasonic shorted a few years back, and have never had any reasons to switch back. This is the only PSU they make that can power dual 295X2s, so there's that, but it's also fully modular (always nice).
LG DVD drive: I needed a DVD drive and it was the first one I saw at MicroCenter. That's really about it.
Windows 7 Professional: Windows 7 because I hate Windows 8 with a fiery, burning passion. Professional because it's the cheapest version that can use 32 GB of RAM (yes, I did just make a price argument in this build).
ASUS PQ321Q: When I bought these, they were the only consumer 4K monitors that could run at 60Hz that were on the market. When competing monitors came out for 1/3 the price less than 2 months later, I felt really, really stupid. That's all I'm going to say about these.
DasKeyboard Model S: I love DasKeyboard's stuff, but since others sometimes use my computer I can't get the one with the blank keycaps. Pity. If this thing ever wears out I'll probably switch to a Ducky keyboard just for some variety.
Logitech G500s: I like really, really heavy; really, really sensitive mice. This can be one of them, thanks to the variable weight and sensitivity settings. Need I say more?
Sennheiser HD 800/HDVD 800: I was an audiophile long before I was a gamer. My primary listening headphones are my LCD-3s, but since the Senns are currently the imaging champs of my headphone collection I use them for gaming. I gave the 800s themselves 4 stars because they're summit-fi and thus expensive as hell. I'd give the HDVD 800 a 3/5 because it has a mediocre DAC chip which isn't worth the asking price. Find me on Head-Fi if you want to talk more about these.
Sennheiser G4ME ONE: I admit, I'm more than a slight Senn fanboy, so I have a headset from them to compliment the 800s. It's got a really nice cable, the mic is one of the best I've ever had on a headset, and the headphones themselves are about on par with the HD 558s (my first real audiophile headphone) so I get nostalgic every time I listen with them. 5/5 would absolutely recommend.

Not-Really-Bonus-Bit-That-Exists-So-People-Don't-Think-I'm-Uncultured: Yes, I am aware of the actual meaning of "Ozymandias" (the poem, not the computer or the Breaking Bad episode). I chose it because despite all the grandstanding I'm doing now, this rig will eventually get passed up in graphics power by vastly cheaper PCs (or, even worse, consoles cringe) and there is nothing I can do about it but upgrade to hold back the inevitable. Poetic, is it not?
