Rezylee :
Need a hardrive (recommend 2tb @ 7200rpm)
Maybe cd-rom?
Os (windows 8.1)
Get a good water cooler closed or open loop, or get a noctua nhd14
Get 16 gb ram @ 1866
Get a 1000 watt axi corsair (extremely good quality)
a) Agreed, hard-drive. Furthermore, an SSD if budget allows it. Also, the Samsung 840 Pro/Evo are good choices! If you want to go with an HDD, I'd recommend the Western Digital Black series.
b) You don't necessarily need a CD-ROM drive. If you look at cases such as the NZXT H440, you'll see they have removed the 5-inch bays. This improves air-flow and cooling performance. A work around to this (if you really need a CD drive) could be to buy an external-USB CD-ROM drive.
c) Agreed, OS. Although, I'd say Windows 7 over 8, but that's just personal preference.
d) He doesn't necessarily need a water cooler. Patchling, if you're planning on over-clocking your CPU of GPU's, then maybe a water cooler will be necessary. However, a case with sufficient cooling will be enough. For a closed loop GPU cooler, the Corsair H100i has a good reputuation. Water cooling is also an idea if you're conscious about the noise of your system. Since this is your first build, I'd say keep it simple in my humble opinion.
e) 16GB of RAM? Maybe if he was doing 3D rendering... No point going overkill if you don't need to. Whatever the case, I'd recommend RAM in the Corsair Dominator Platinum series. Preferably, a set with 1600Mhz speed, and CAS 8 latency.
f) 1000W again seems a bit overkill. If you're planning on doing Crossfire/SLI, then this may be a good idea. Furthermore, if you're planning on getting a case and filling it with fans, it may also be a good idea also. In terms of branding, I would recommend anything from Corsair for PSU's.
Patchling, for your motherboard I would consider looking over the ASUS Maximum VI series. They have a range of models to suit your price, and are reliable and built to a high quality (as per with ASUS). I personally have the ASUS Maximus VI Formula, and love it very much. Plus, it's ROG armour looks badass
😀
Also, for case fans I would look into Noctua (if you have the money) or Corsair. Both offer air-flow optimised and pressure optimised fans. Corsair's cheaper, but Noctua are of higher quality. Corsair's quiet edition fans are famed for their low noise profiles. Since this is your first build you may want to know the difference between air-flow and pressure optimised fans. Air-flow fans are designed to push a large volume of air through a void space, as the air flows through the fan, it tends to scatter, and be not directed. This is ideal for places in the case with little restricted space (such as an inflow on the front, and outflows on the back). A pressure optimised fan is designed to channel air in a focused manner. These make them suitable for places that would otherwise have restricted airflow, such as on an HDD cage, or behind your mobo.
Hope this helped!
