Bought 1 of these computers at work last august, needed to be pretty fast, had to run a couple of heafty programs anf be link to equipment in the work area. the computer we had before that was a very old hp which had come to the end of its carrer really. when we got the fujitsu we did not know ourselves. was a bit concerned about running the programmes on it, but it was no problem and it ran them with ease and is still a good as ever. it was so good we invested in another. productivity in work has increased also as we are able to get twice as much done. on eash tower there is a cd/dvd unit and 2 usb slots (more in the back) not floppy disk space. but i suppose this is obsolete. Very good purchase abd work recommend for personal or work use as it is a very capbale computer.
