I must answer yes. ;-)
I've got a sam440ep 667. And i use it daily,as my main computer. But get a decent gfx card. The ep has onyl 64mb and it's a tad little. And you can use uae for classic gaming. Get the 733mhz version. And the hd size is no problem. I have a 500gig hd.
I ordered a prebuilt setup,was nice. Just plug the cable in and turn on,and everything worked as expected. :-)
