I wanted to build a gaming box that would smoke a console and last for awhile. It all started when my wife asked me to teach our 9 year old about computers. I figure what better way to learn than to build one together.
I reused as many parts as I could from old computers we had. My "recycled" case wouldn't fit everything right so I called a local repair shop and he sold me an old case for $20.
I named it "Sleeper" b/c the case is straight from the 90's, complete with scuff marks, dents, etc but the inside is all modern. It doesn't have the best airflow, but Temps stay around 30 c when idle and 60 c under load. The case didn't come with any standoffs and I don't have a good local parts store. It provided a great chance to teach my kids some Macgyver skills. I took two washers, wrapped them in electrical tape, and poked a hole in the middle. I used six of them for the build and it worked perfectly.
Went with i5 4690k b/c it fit my budget and needs. I'm still waiting and saving for a better case and water cooler before I overclock it. I also plan to upgrade it to an i7 when games and things get beefy enough to require the extra cores.
Nvidia GTX 970 was a splurge purchase. I could have reused a eVGA GT 640 I had, but figured it was time for the upgrade. This card rocks!
So far Sleeper handles everything I throw at it. ~10 sec bootup. Stable Temps (I little higher than I want, but given the case I'm using its OK). GTA V at max settings @60 fps, Arma III at max settings with no problems.
