I, infact have 2 setups, my desktop and my server/laptop thing (its on 24/7 so i call it a server)
i use my laptop as my server because it is low power, and does what i want it to do, which is stream movies to the TV's & Media devices in my house (iPads, laptops etc.) my laptop has two 372GB Toshiba 5400RPM HDDs, as well as a 2TB Western digital Elements, it has 170GB or so free on it.
my desktop, i use it for games & movie encoding.
it has a 1TB Western digital black for its boot drive (because it is really cheap, great warranty and has a TON of storage & is really fast)
To record my gameplay to, i use a 1TB Western digital Blue, because it is really fast, and allows me to record gameplay with no lag @ 60 FPS
My 2TB WD Elements also houses my music, i have about 2000 songs so it is easy to be able to access them from anywhere in my house.
