Apple improves their Mac Mini with as much as 1TB of storage, but does offer models with 500GB and 160GB of storage. Get prices and specs here.
If you just were not happy with your Mac Mini good thing Apple has updated it. With the new Mac Mini you will get a 2.26 GHz Intel Core 2 Duo processor with a 2GB of DDR3 1066 MHz memory, a 160GB hard drive, five USB 2.0 ports, FireWire 800, an nVidia GeForce 9400M integrated graphics and a SuperDrive. The Mac Mini with these specs can be all yours for $599.00 ( 399.87€). Those are the graphics for one of the Mac Mini´s but if you need more then the Other Man Mini that is obviously more expensive might just be the one for you.
The Mac Mini that will set you back $799.00 ( 532.44€) gives you 2.53 GHz Intel Core 2 Duo processor, a 4GB of memory and a larger 320GB hard drive, but if that for some reason is not enough for you then you are going to need the $999.00 ( 665.62€) and for that money you will get specs such as two 500GB hard drives for a total of 1TB of server storage in the tiny 6.5-inch square by 2-inch tall Mac mini enclosure. If for some reason that is still not enough then you are out of luck because the Apple Mac Mini doesn´t get more powerful than that.
