To upgrade
I don't know what it is, but it doesn't take a week since I bought an internal or external upgrade before I want another one. I mean, I can't keep on. Look at my poor PowerMac G5
No more SATA bays, no more DIMM's 
Got an USB2 drive. USB printer. USB scanner. Logitech MX1000. 5.1 surround system with receiver.
But i still want to upgrade. And I don't know with what
