A new desktop computer

It's been a year since our desktop computer crashed down and my husband tried to fix it many times, sadly he failed. I am quite afraid that some of my files cannot be recovered anymore. Lesson learned, always have a backup of your files. This year we are thinking of getting a new desktop computer and we are looking at Ordinateurs de bureau, a french brand of high quality desktop computers. I just cant work at my netbook all the time because it cannot accommodate all the files that I have. Can you suggest other good brands as well? We are still comparing prices and specifications and we welcome suggestions.
