compatibility question about a new hard drive

I currently own a Dell Dimension 8250 and I am about to order a


WESTERN DIGITAL - 160GB Caviar Special Edition Internal EIDE Ultra ATA/100 7200RPM Hard Drive with 8MB Cache
160 GB, Internal, 7200 rpm, 3.5-inch, 8.9 ms Seek Time, EIDE Ultra ATA/100 Interface, 100 MBps, 8 MB Cache
Dell Part #: A0100036 | Manufacturer Part #: WD1600JB

I am basically just wondering if this drive is compatible with my system or if there is any reason it wouldnt be compatible or if there is any extra parts I need to make it compatible or to install it. I am going to copy my master drive over to it and make it the new master drive then format my old master and make it the slave drive which will make my computer having 2 hard drives total once the new one is installed. Any replies to this question would be greatly appreciated.

Thanks
Jeff
