My friends and I typically organize LANs every other weekend or so (mainly CSGO with some DOTA 2 and a few other titles). When I built my PC, I was short on cash so I had to buy a mid-ATX case and motherboard, but even specs-wise it's not a very good machine with a first generation i5 and a GTX 210. Getting the Zbox would be a big help cause that'd mean I wouldn't have to carry around my old PC around when I go to LANs, I would be able to play newer games (Fall out 4 and The Witcher 3 especially), and I could give my PC to my little brother as his introduction into the PC gaming community.
