I built this back in April and got sidetracked with selling 2 houses. This was built to replace my '09 Alienware Aurora R4 that was getting pretty dated.
The Phanteks case was well worth the money. It has more room than the NZXT h440 that I was considering, and thick gauge aluminum wins over steel any day of the week. This is the first pc that I've had without a 5.25 drive, and I don't miss it. I picked up a cheap cd/dvd burner from Best buy just in case, but I've only used it once to install the motherboard drivers during the initial set up. The cable management in this case is a little tight, but this the first time using a case like this so it's probably just me. The only thing I would advise on a build like this is that if your house is dusty, you had better learn to love dusting and cleaning this case out once every month or so.
Processor, motherboard and cooler I picked up as a package buy on Amazon. I'm happy with the 6700k over the i7-930 in the pc that I replaced. I prefer liquid cooling for the cpu to cut down on noise. I've always had good luck with MSI products and I'm happy with the features on the Gaming M7. I did manage to bork a BIOS update and their flash recovery worked like a champ. I did have some issues getting a stable OC with the memory. I'm attributing it to DDR4 being relatively new, and the fact that I bought 2 different sets of memory instead of all 4 sticks packaged together. I recently bought a matched 4x8gig, DDR4 3200 corsair Vengeance "whoopdedoo" edition LED sticks (CMU32GX4M4C3200C16R) that seem to play well together using the stock XMP settings so far. Last note on the motherboard. It has 10/100/1000Mbps capability and the new AT&T gigabyte internet here is amazing.
I went with the Samsung SSD for windows, drivers, software. I will NEVER build another pc that doesn't at least have a SSD boot drive. Within 20 seconds of hitting the power up, I'm 100% up and running. I'm still hesitant to go 100% SSD because I'm a troglodyte and I'm afraid of losing stuff and not being able to recover it like I can from a HDD. My Steam library and all my games are on the WD 2tb Black, and I had the seagate 3tb drive left over from a previous build that I use to store all my music, pictures and movies, and as a backup drive.
When I originally built the pc back in April, I had 2 MSI GTX 980ti's in it. The 1080s came out shortly after and I told myself "Self, there's NO reason to buy the new stuff until at least a year or two from now." I didn't listen and bought the 1080 Gaming X's as soon as Newegg had them in stock and they would let me buy more than 1 at a time. The run WAY cooler than the 980ti's. The top card with the 980's would thermal limit rinning Valley Benckmark hence the fan near the GPU's. I was going to take it outafter I replaced the 980's but the bracket it's bolted to is riveted to the bottom of the case and it looks cool. I have replaced the case fans with the Corsair ML140 pwm fans. Running on low they move a lot more air than the AF140's did and they dropped my case temps to within 5 degrees of ambient. Well worth the extra money.
I like windows 10. I dunno if I like it better than 7, but I haven't had any problems with it for the exception of a bad first install. I've used Eset on all of our pcs and laptops for the past 10 years and haven't caught a virus. Corsair RGB mechanical keyboard, and m65 mouse are NICE. The price is a little off on the Logitech z-550, I guess it's because they don't make it anymore? The NZXT Hue kit is nice, it adds a little more ambience in the black case. The next purchase for me WILL be a 4k monitor, either the Acer or the Asus 27inch gaming display.
Last but not least, I think the modular power supplies from Corsair are the bomb. I like the nylon covered wiring, I think it really sets things off and gives a custom look. I wish I had shopped around more when I bought the cable kits, because Cablemod.com has come cool color combos that Corsair doesn't offer.
Other than that if you have any questions, I'll answer them a little faster. I spent all summer selling 2 houses and moving. I'm glad to be moved in to the new house and I'll be more available. I should probably update the build while I'm here too.
