They cost more then my PC
I build all my own systems.
I'm on my laptop right now... so I can't say much.
BUT... my tower is another thing. A CoolerMaster Centuriun box; Coolermaster 600watt power supply; Gigabytye b75m-d3h motherboard; Intel i5 3330x4 cpu, 8-gigs of ram. Never mind the extra 3 cooling fans, drives
(1 120-gig ssd drive, 1 1-tib drive, 1-2-tib drive, 1 500-gig external optical drive, 1 500-gig external-passport usb3 drive.
Never mind my 1 4-gig, 1 8-gig, and 3 32-gig usb sticks.
