Barebones computer With CUSTOM hardrive??

Unless the motherboard is the same, there is a very slim chance that you can move a hard drive with an existing operating system installation to a new system without having to reinstall the OS.

Yes, assuming the board can accept it: sata/Ide. But as said you would need to reinstall the OS.

BUT! why would you want to buy a "KIT" (heavy on the quotes) which gives you sub-par quality parts for not that much of a savings?

Instead tell us what you were planning to buy and whatnot, your budget, .... and we'll put together something better.

Fill this out.

if you can find the extra 30 dollars  
you could build better trolling on newegg yourself, but I just found 2 combo deals in 20 seconds   Happy hunting...

Do either of these have a good Graphics Card for gaming?, i really like the rest of the specs

Neither of those combo deals have graphics cards included, I'd just finished work this morning and posted them as suggestions  
If you like those builds add one to your cart on newegg and it will do the ' people who bought this also bought' list, and therell be suitable cards listed.
they do look to be decent enough to handle most games though
