Plenty of capacity for a MAC Mini host (Lion), with a barcode scanner, and credit card terminal. All transactions are updated in real time to the server, which runs Acclivity's Account Edge NE accounting software. Both the server and the network equipment are protected by separate Tripp-Lite UPS products. The entire network runs gigabit ethernet, and is almost PCI compliant. Only the credit card terminal needs to be updated to achieve full PCI compliance.
Our IT manager charged the system in his office so I received it about a week after purchase. It has now been in my office for a week and it still gives off a fairly strong odor. Reviews on other websites for similar TRIPP products seem to indicate it may take up to a month to "out-gas". Other than this, the unit seems to work well. Not all outlets are usable if you have several of the large plugs typical of external drives.
