Assuming that the HP isn't so proprietary that it makes adding another drive tricky, yes, I do have a 350 or 500 kicking around here somewhere.
Are you suggesting installing only PS on it?
Thing is, this machine is supposed to be the inexpensive solution to merely being able to see client's files, and a little real-time design work with them.
Hell, the CorelDRAW would probably be sufficient, but I have gotten so used to having PS for when I need it, the new machine feels a little naked without it.
I just wish that they would have skimped on the hard drive a bit to make my life easier. I don't need 1.5 T and PS7 can't even recognize it!
