The RAM was pretty easy, though I ended up taking the computer down and out to the porch and blowing it out with the compressor and air nozzle. Since I had it open, that made it easier to get at everything, and I was able to even blow out the fan on the video card.
Vegas was there when I got home, and I ordered it on Tuesday-- it was just over 24 hours from when I ordered it to when it was delivered-- I even got the notification that it shipped after I had it installed. Of course, they're based in Madison, but still, that was freakin' fast. And it was standard shipping.
Then I went to bed.
