You're right, that PC does look nice, but take a look at the price.
I've always built my own PCs, and I've always been able to get a cheaper price than the pre-made ones. A lot of those things on that PC aren't necessary in my opinon. Based on the stats, it looks more like a movie-focus PC, and gaming second. From a movie-focus PC, the blue ray player, two hard drives, and the large amount of RAM makes sense (barely). From a gaming point of view, you don't need 32 gigs of RAM; you don't even need 16. 8 GBs is all you really need. If you want to feel safe, totally superior, and your friend has a wide budget, then go for 16. G.Skill is a great brand, and the one I'm currently using. They also have a lifetime warranty so if something goes wrong with one of the sticks you can return it and they'll ship you another one free of charge.
In terms of hard drive, start out with just 1 TB. You don't need that SSD, unless again, your friend has a big budget and wants all the latest tech. I'm running on just 1 TB which holds my OS plus 20+ games (I've filled up about half). I wouldn't worry about stocking up on more than one hard drive unless you start taking up space on the first one, which is hard to do with a terabyte. In the event your friend does run out of room on that hard drive, make sure he gets another terabyte hard drive, nothing below. Saves you a lot of headache if he runs out of room again, trust me. Or alternatively he can get a 2 TB hard drive and not worry about exceeding it which is extremely, extremely hard to do.
Not sure how the blue-ray drive works with games. This is a shot in the dark, but I'd think a blue-ray drive would only work with blue ray disks. Your friend would be safer getting a seperate CD drive in case DVD only disks don't work (I've run into that problem), and a DVD drive. They're both fairly inexpensive, you can find them cheap for $40. Speaking of which, you don't need something high tech for drives, Sony is the preferred brand I recommend.
After all that's been said, we need to know your friend's budget for it. If its 2000 AUD ($2299), he can definitley get more and better for his money than that pre-made one. Triple screen set up, perhaps? Duel GPUs? A fancy steering wheel for Need for Speed?
