I got 500GB hard drive instead 320GB, and as another bonus 2GB of ram instead 1GB! So I'm a lucky boy
Btw, It was the Austria AppleStore, and iMac 24-inch.
I've just been upgraded big time. I ordered:
2.8Ghz, 320Gb HD, 2 Gb RAM, 256Mb ATI Video.
Received:
3.06Ghz, 1Tb HD, 2Gb RAM, 512 NVidia 8800GS!!!!!!
Very pleased. Although slightly guilty; will they ask for it back?
