Last year (2015) I was lugging my large CM690 desktop around between my place and my GF, since my laptop wasn't cutting it for the games we wanted play (damn you, ARK!).
I decided it's been a few years and I'm probably due an upgrade, so I decided to build something powerful, but more mobile. I went through a few design choices, but ended up going with the Corsair 380T. While bigger than planned, the carry handle and full-szie GPU and PSU support (and the price inside my budget) convinced me.
Thanks to the great Roccat Tusko carry bag, this box can now very easily just go with me wherever I need it. It is my primary gaming rig, and I haven't played around with OC settings yet. But it does what I need for now.
I will add some more pics in the future, I just added what I had on hand for now.
