This was my first PC build and I couldn't be happier with the result! I started out with a 3.0ghz pentium G860 and a Gigabyte GTX 650, and just upgraded to the i5 and the GTX 660. The previous set up was surprisingly suitable for gaming, but doesn't come close to the performance that I have now. My motherbaord is last gen, but with a bios update I was able to get this i5 working perfectly. And even though it's not the current gen it still has PCI-E 3.0, USB 3.0, and support for 32gb of RAM so I didn't need to upgrade. I do plan on getting more RAM, but for an off brand like Pareema this 8gb stick has performed great and I wouldn't mind buying more from them! I also need to get a faster wireless card. I only have 1 LED fan because I don't like to have too much light in the corner of my eye. I put the 1 blue LED fan in the front so that there's a small glow coming from the front air vents. The power supply is under a heavy load with this processor and graphics card so I will upgrade soon but for now it will handle it.
I've been happy with my hard drive too. Unfortunately it's refurbished because my 2010 model had bad sectors so WD replaced it with this, but it has been great. The 2.5'' drives are just extra that I had. I might install windows 7 on the 320gb, and the 160gb I'm just using for backup space. I have no complaints about the mouse, and the speakers sound great. The monitor is incredible. The response time and the IPS blow me away. It's perfect for gaming! The keyboard is cheap but it's comfortable and I don't plan on upgrading. I'm also really happy with Windows 8. Contrary to what people say, it actually works great for gaming. A couple of my old games like San Andreas only work in compatibility mode, but it's not a set back because it takes 3 seconds to set it to compatibility.
In the end my only complaint is the slow wireless card. Even my off brand RAM performs great. I would highly recommend the monitor, the processor, graphics card, and even the case! It has great wire management capabilities, includes a 120mm fan, and has a great simple design!
