Noone is going to point out the fact he has an open case 5400 RPM hard drive as his only storage device? Really?
You all realize after he fills that thing half way and day to day usage kicks in, that thing is going to take 4 hours to search the entire C:/ index
Swap it out for a lower storage 7200 RPM hdd or get an SSD to run Windows and other important programs on, alongside the HDD
