Expansion Bay: Dual Solid State Hard Drive Hot Swap Bay
Optical Drive: DVD-R/RW/CD-R/RW (DVD Writer 24x / CD-Writer 48x)
Storage Set 1: 1x SSD (512GB Samsung 850 PRO)
Storage Set 2: 1x Storage (1TB Western Digital - Black Edition)
Storage Set 3: - No Thanks
RAID Config: - No Thanks
RAID Card: - No Thanks
Internet Access: High Speed Network Port (Supports High-Speed Cable / DSL / Network Connections)
Graphics Card(s): 2x SLI Dual (NVIDIA GeForce GTX 980 4GB (ASUS Strix Edition)
Sound Card: Creative Sound Blaster Zx (Includes Audio Control Module)
HPC Processor: - No Thanks
Extreme Cooling: AIR: Stage 2: Noctua NH-D15 (Extreme Performance)
H20 Tube Color: - Not Applicable, I do not have a custom HydroLux liquid cooling system selected
Chassis Fans: Upgrade All Fans to Corsair Airflow Performance Edition (Up to 6 Fans)
Internal Lighting: Remote Controlled LED Lighting System (Multiple color options and lighting effects)
Airflow Control: Digital Storm Thermal Management Control Board & Software
Chassis Mods: Fan Blow-Holes: VREG/CPU & Graphics Card Area: Laser Cut and Mount a Side Window 140mm Fans
Noise Reduction: Noise Suppression Package Stage 2 (Optimized Airflow & Fan Speeds with Noise Dampening Material)
LaserMark: - No Thanks
CPU Boost: Stage 2: Overclock CPU 4.5GHz to 4.8GHz (Requires High-End Motherboard Selection)
Graphics Boost: Yes, Overclock the video card(s) as much as possible with complete stability
Memory Boost: Memory Fan Kit Only (Does not include memory overclocking service)
OS Boost: Yes, Disable and tweak all of the non-crucial services on the operating system
Windows OS: Microsoft Windows 10 Professional (64-Bit Edition)

For the power supply, do i need 800/1000/1200W?

Memory wise I'm just not sure if I need 16GB or 32GB and what frequency is best?

I'm trying to avoid liquid cooling, will this config i have run cool enough?

Any input is appreciated, and is the Apollo more advantageous compared to the Velox with an identical config?

Forgive me I'm new at this.

For the power supply, do i need 800/1000/1200W? a good 1000W psu should meet your needs.  the two vid cards will pull 300w'ish (each) under max load and the cpu another 200w'ish.  extreme oc'ing the cpu and gpu(s) will increase this some. 

Memory wise I'm just not sure if I need 16GB or 32GB and what frequency is best?  for gaming, you won't need 32GB. 

I'm trying to avoid liquid cooling, will this config i have run cool enough? that's the best air cooler you can get and it is actually more quiet and performs better than most AIO closed loop liquid coolers on the market.  it won't come close to a custom water loop, but neither will any AIO. 

however, things to be aware/concerned about are the size/weight of that air cooler on the mobo (especially during shipping).  i myself (as well as others) have experienced shipping damage directly related to this big air cooler and it's older sibling the D14.  there's also the matter of ram clearance, so make sure they are compatible.

Any input is appreciated, and is the Apollo more advantageous compared to the Velox with an identical config? i have no personal experience with either case, but i will say that the Velox' construction seems better to me for air cooling (at the expense of more noise).

Are you planning on using this machine for productivity tasks like video editing or just for gaming?

If gaming is the most intensive task you'll use it for, then the X99 platform (the 5930k processor) is not going to help you much. Theoretically it might help in the future if games get better at utilizing more cores.

Right now, the 6700k is going to be better for a gaming build -- and cheaper too. However, the extra cores of the 5930k have advantages for tasks that easily scale computationally -- gaming just isn't one of them.

I'm also having a lot of trouble trying to figure out if I should go air cooled or a liquid cooled system, I originally wanted to stay away from liquid but I am also looking for longevity out of this build. Any insight on which method is better?

unless you're playing games on a notebook with only an iGPU for graphics i wouldn't worry too much about getting the fastest memory possible.  faster memory also helps productivity usage, but from a gamer's perspective you'll be perfectly fine with what DS offers as a baseline in it's DDR4 systems.  so, imo, it's just not worth spending the extra money on upgrading the memory over the baseline. 

if you need/want a technical review/article to support my opinion please read: http://www.anandtech.com/show/8959/ddr4-haswell-e-scaling-review-2133-to-3200-with-gskill-corsair-adata-and-crucial/10

it's tested/based on Haswell-E memory scaling, but it should very well apply to Skylake too.

also, i wouldn't worry about memory fan kits and overclocking ram beyond its XMP profile setting either.

You guys are awesome thank you for all the input.

Okay so im leaning heavily towards the Velox but I have one question that hopefully someone can answer:

If i stay with an all air cooled system (Noctua NH-D15 fans) how often will I need to remove dust and clean out the Velox and is it easy to do so?

Alright haha well thank you for that info bprat22. Should be putting my order through very soon (next day or so).
