Took forever to ship.  When it arrived, I took it to my computer guy to have everything transferred from my old computer to the new one. Well, he found there were 2 rams of different speeds.  He said the computer cannot run like that!  He did have a couple of memory cards to replace the ones that came w/the unit.  Unfortunately, I now have 4 bits instead of 16.  The cards he took out were dirty & scuffed up!  When I went to install some software, the CD tray would not open.  I had to "encourage" It w/a thin knife. It seems very flimsy as if it might fall off/out. The computer does run well, so far.  I'm apprehensive.
