Sorry! You'll have to do your own homework. You can easily do that yourself.

 

Power supplies are easier. Give us a prospective build and we will give you a recommendation.

For a Gamers point of view and as far as full tower gaming case is concerned, The best choice to start with as your best reference are, Coolmaster's HAF 932 or the CM Strom Sniper case (tough considered as a mid tower but its height is the same of those full tower's and is considered one of the best gaming case available to day). For the Thermaltake, their Armor, Armor+ and Speedo and for Antec, its their 1200 gaming case. When it comes to good mid tower case that could fit 10+ inches or longer video cards, i recommend the Coolermaster's HAF 922, CM690 or the NV690(Nvidia edition of CM690). For Thermaltake, its their Element G only, The others offer only average not so efficient cooling features and some of them are not suited for long video cards. For Antec, its their 902 enclosure.


Hope this helps.  

In addition:

Since you also mentioned Gigabyte, well, i could only recommend
their 3d Aurora gaming case, here's why:
