I have had an ibuypower battalion 101 D900f for about 2 years and its starting to become outdated and slow, and has also been having some heating issuses, so i was thinking of selling it and building a new desktop. First of all, how much do you thing i could get for the machine considering it was $2600 new and is still in great condition? Also, do you think it is a good idea to go with the desktop?
