Is this comp worth the price?

Well, let's take a look, shall we?

AMD FX-4300 3.8Ghz Processor - $105 is lowest price on Amazon.

8GB DDR3 SDRAM - No specifics, but we'll call it $75 for a decent stick set.

1TB SATA Hard Drive - I'm going to hope that they mean SATA III. That's a solid $60.

24x DVD+/-R/RW drive - We'll say it's a high-end drive. $20.

Nvidia GT 610 Graphics Card - Goes for a solid $40 on Amazon new.

Thermaltake Commander Case - Easy to find at $53.

AMD 760G Motherboard - $58 for it. Not very high-end.

500W Power Supply - You can probably find a good one for $50.

AZZA Gaming Mouse & Keyboard - $40 for both of them.

Total Price based on Amazon: $501.00

You're saving a whopping $3 while this thing is on sale. However, I am strongly against purchasing this. They were very ambiguous with the frequency of the RAM (could be 1333Mhz, terrible). Not only that, the peripherals aren't great, and they're shoving in a terrible graphics card. Upgrade the graphics and the peripherals and buy this yourself. A decent graphics card and better peripherals (remember you need a monitor if you don't have one) will probably run you closer to $650, but you'll have a much better experience.

If you don't want to do that, buy the build @ $498.00 before shipping, and then buy a graphics card and put it in yourself. A GTX 750 Ti will run you about $120, and it's a really solid card.
