The hard drive is just a regular drive with big storage. If you want speed, get the Western Digital Raptor drive. Cost more, but it spins at higher RPMs. They're SATA drives and transfer rates are a little faster.
Motherboard is good (I see you witched over to AMD). That company (Newegg) unfortuntaly, doesn't ship to England or anywhere overseas, yet. It's got 4 USB support in the rear and 2 more for the front of the case (once you hook it up to work there).
Can't go wrong with that powerhouse processor. That's pretty top notch.
As for your RAM, it's a ValueRam. Not a performance module. Get something like Corsair XMS, Crucial Ballistix, or Kingston HyperX something like that.
IMO, I can't see the use for 2 burners. All you need is a DVD burner that's it. If you want to make a disc to disc copy, you put the original DVD or CD in the burner first to be copied over to the hard drive, then the software prompts you to insert a blank disc and takes the data off the drive to be transferred across to the new DVD.
Floppy and Zip are pretty standard so no change there. Doesn't matter on the qualtity of it. Rarely used these days.
Video card is a 6600. It's a good video card, but I would think for the money you're putting into already (especially the Toledo Athlon X2) you may want something a little better like a 6600GT, 6800GT, or even a powerhouse 7800GTX. If you can't afford it, upgrade to a 6600GT instead of the base 6600 model.
That sound card is pretty good, but be aware that it comes with NO drivers. You must have drivers to make it work properly. After the drivers are installed, plug the speakers into the right port and you have sound. Make sure you double check the volume control. Windows always have them set to a minimum upon installtion.
Case looks good too. It's a lot to go through so we'll see what other people say.
