E-Win made a surprisingly great gaming chair with the Champion. Not only does it have features like 4D armrests, but it is one of the best chairs to sit in on the comfort level as well. What really makes it stand out is in being one of the most affordable chairs in it's bracket.
Patriot is pushing into the gaming market a little harder with the Viper V570 Blackout. The ergonomics aren't the best, but the trade off is a mouse that seems to improve precision and reaction. The RGB lighting is amazing and the button layout gives gamers a lot of ability options.
Rosewill has a lot of features and great lighting on their Neon K85 RGB keyboard. The mechanical switches are nice, but they opt for Kailh instead of cherry. The price makes it worth considering and if you haven't tried a mechanical keyboard for gaming, then don't wait any longer!
Enermax offers an excellent PSU with the MaxTytan. Sleemax is a great feature for those who don't want to sleeve cables themselves. The RevoBron is a solid budget option that doesn't cut important features for a clean computer build. Respective to their budgets, each unit has great quality.
Noctua offers excellent performing low profile CPU coolers with the NH-S12L and NH-L9a-AM4. For those in the SFF computer market, these low profile coolers are a perfect match if you need something better than a stock cooler. If beige and brown isn't a problem.
GeIL does a great job with their RGB lighting and high out of the box frequencies. Where their RAM falls a little short though is in the overclocking department. Since many choose not to overclock their memory, the Super Luce RGB Sync AMD kit might be just right for you.
