Titanium PC cases that have turrents on as no one would spend $3000 and not lock that thing away like a trillin dollars... Someone breaks into your house and your graphics card alone is worth $3000 chances are your full PC is worth well over $5k...
Thieves would love people buying this card break into a house steal 1 thing a tiny graphics card its like finding a diamond or a brick of gold.
You assuming the criminal is tech savy and knows the difference between a $1500 best buy machine and a gaming machine with a 3k videocard.
Secondly time is not on your side while doing a break and enter unless you have checked out the house in advance and know when the residents will return.
Its basically get in grab what you can that looks of value which will be jewelry, tv , stereo equipment before you even get to the computer then get out ASAP.
