Yes, I basically have two although one is less of a beast than the other. First off is my laptop I've called "VANQUISH" (usually written without full caps rage). I sold my MacBook Pro, Dot³, for that back in early 2012 so I could play Battlefield 3 Vanquish was only €580,- euro and in the end I actually gained €1,- of profit by selling Dot³

My biggest pride is my barely 6 months "Gojira". Yes, I named it Godzilla and I will add some pictures later to show you why. Gojira costed around €950~1000 but I've sold the initial power supply and the i5 4670K to get an i7 4770K and a 850w PSU.
