Welcome, and a great choice of computer there mate
One thing to change though (only a little niggle), the processor.
Not the chip itself though because the 3000+ is great and very overclockable (if thats what you wanted to do with it), but the type of processor it is is an old manufacturers type of build.
I'd try and get that same processor in the new Venice core (won't cost that much extra) which has a few advancements over the Winchester before it, which was a build after the Newcastle you have chosen that uses 90nm manufacturer to make the chip run cooler.
Doesn't matter if you don't want to though, but might mean a cooler pc and better memory enhancements, and you'd have to change the motherboard since the Venice core is a 939 pin and not a 754 pin like the one you have chosen.
The 754 socket of that motherboard and processor you see that you have chosen will make it very hard to change processors in the future since 939 is now the standard for new ones, so if you ever wanted to upgrade, you'd end up having to change the motherboard again anyway, so why not do it now?
So if you can, get the 3000+ in the Venice core, and step that motherboard up to a 939, and this shouldn't be hard to find with the same specs as the one you have chosen.
I hope this helps!
