If you haven't yet try Battle Royale. From what I hear they are pretty similar except battle royale has more gore than the hunger game movie is going to have. Also read the long walk by stephen king if you enjoyed hunger games as it is a listed inspiration for Battle Royale.
Some times you get lucky that's why I said try. I actually bought all my parts there because the people were helpful. They gave me some deals and when I was having trouble with my seating my cpu cooler (for whatever reason I listened to my dad to put a stock cooler) they gave me a good deal on a good cpu cooler seated it and put the thermal paste on for free. They also have a cheap warranty with direct replacement. But yeah look at the tom's hardware for great builds. But also following tom's hardware I was able to find every part that was listed in that build there.
