I started building this as a present to myself to bring in 2016. I had always been a laptop gamer/designer and never had a dedicated desktop for myself. Shortly after browsing a few youtube videos for custom water-cooled PCs (Pauls Hardware, Jayztwocents, Linus, etc) I decided I must build one! -- This was much more exciting since I hadn't actually built a desktop before, either.
I had initially been looking at a wall mounted PC, but I didn't have the shop type materials to build it myself here, so I decided to go with the Thermaltake Core P5 as a nice modular type case. Since I was going with a water-cooling set up, I decided to go against an i7-6700k, DDR4, etc newer gen component list (since I could get relative performance with this setup).
Have been very pleased with all the benchmarks I ran on AIDA64, CinebenchR15, and Unigine Heaven! Will likely be adding another GTX 970 in SLI in the future, whenever I get around to getting another GPU waterblock :)
Update : 5/2016 : Desk setup is fairly done, SLI has been up for a little while as well. Updated pictures to show -- no more pci extension cables for a vertical stand GPU. Added in an MSi SLI bridge, EKWB backplates and misc. desk improvements!
