That motherboard sucks, go with something else.
The hard drive is OK but if I were you I would go Western Digital.
Power supply is beautiful.
Video card is perfect because you don't demand the every edge in gaming. The 5 series is better, but you personally aren't going to notice the difference.
Ram is good. Matching pairs are nice, but the only place you will ever give a rats ass is on a benchmark and those are just numbers. If the ram is name brand and of the same spec it can be any brand in any order in mixed and matched sizes. Who cares if they match as long as the specs do. I perfer my sizes to match also (ie 2GB x 4 instead of 2gb x 2, 1gb x 2 or 2gb x 1, 1gb x 3 etc) but you can do whatever the hell you want. Name brand quality ram in any bank order and your ass dyno won't see a difference to matched.
That's my rant /
