I will point out that with increasing energy costs, the price difference between a 256GB model and the next size up might not be so significant.
Assume a standard PC idles at 120w, for 2000hrs a year ( 6 hrs) a day, versus 300w due to overclocking and disabling the power Saving mode (video card, cpu, pcie, usb). 180w/1000 at 20c / kwhr, that equates to $72.00 /yr.
Probably more if you have extra hdds/opticals that aren't sleeping.
These days that could buy an upgrade from a 128 to a 256GB, or even a spare 128GB to slap your OS on, or raid together.
