I'm toying with the idea of building a custom PC for my weekly gaming sessions and I would really like to build something that I can plug into my TB display in place of my MBP. Another desired feature would be that it be as compact as reasonably possible. I realize that with any decent GPU that it's not going to be Mac mini sized (or even Mac Pro size), but would like to get something that I could just toss up on my desk for my gaming time and then stash it away in the closet or on the shelf for the rest of the week. Has anyone seen a decent compact gaming PC build that has Thunderbolt support? TB2 is all I need, since I only have the TB display to use with it (and I think that's actually TB1 anyway). But I do want to have a discrete GPU, otherwise I might as well stick with the MBP. Thanks!
