I have an iMac 333 with the original 6 GB hard drive. I was wondering if it would be wise to install an internal drive. The one I'm looking at is the WD800JB Western Digital 80 GB EIDE Ultra-ATA 100 7,200 RPM 8 MB Buffer. I found it for 70 dollars and was wondering if that would be a good idea. I was also concerned how it would look on the front of my iMac since the original hard drive matches the blueberry iMac. Thank you for any help
