This build started because of a build last year - https://pcpartpicker.com/b/Mpxrxr - It was fun to play with, but I love new toys...I decided to build a 100% new machine for Linux for the first time.
When I did my first build last year, I was torn between the CM Storm Scout and Storm Scout 2 cases. I chose the CM Storm Scout - https://pcpartpicker.com/b/yXgscf - and built my dream machine at that point in time. My buddy went with the CM Scout 2 - https://pcpartpicker.com/b/NR8KHx - for his new build last year. I liked the CM Scout 2 enough, I decided it was the case for this build.
I used the motherboard for a friends build - https://pcpartpicker.com/b/HXjXsY - last year and really liked it. I was thinking the Pentium G3258 was the perfect CPU for this build, so I started looking for a board to overclock it, and I remembered how much I liked this board, the UEFI BIOS, the color scheme etc...And I got it at a great price as they were disappearing from vendor stock.
UPDATE: 2/10/19 swapped out the Pentium G3258 for an i5-4590 that a friend gave me from an old work desktop that was getting parted out.
I built a machine - https://pcpartpicker.com/b/KDyfrH - for my wife earlier this year, so she could play Diablo III online with me and my buddy with the Fatal1ty Z87 Killer build. I LOVE the Pentium G3258! It's a little overclocking beast! So I had to have a second one! The CM Hyper 212 EVO is my favorite cooler, a real no brainer for this build.
I love G.Skill RAM. I've used the Sniper Series in all of my builds, if it's not broke, don't fix it...16GB is probably overkill, but I figured the price was too good to pass up. Running Linux, Wine, and maybe some VM stuff...can't hurt...not a budget breaker by any stretch...and who knows, the last Linux machine ended up with Windows 7 on it before I sold it...
UPDATE: 2/10/19 wife's motherboard died a few months ago, her new board used DDR4, so I took her old DDR3 and put into this machine. Now it's maxed out at 32GB. Yes they were both identical kits.
I'll never build another machine without an SSD. EVER. I wanted something with 240-256GB, to me that is a price/size sweet spot right now, and a perfect size for the OS drive. Mushkin is a brand I know and trust. Great price, perfect size, color matches my scheme...perfect. The HDD I've had laying around, added it as a data drive for my Steam Library more than anything else. The SSD won't hold all my games, and the HDD is 7200 RPM, and It cost me $0 for this build, so that was that for the drives. No use for an ODD in this build. Installed OS from USB stick.
Graphics card, this was tough for me actually. I've always bought EVGA cards. I wanted a Gigabyte WindowForce. The card I wanted, the logo lit up in blue. I HATE blue. I saw the MSI GTX 960 100ME and I thought PERFECT. I bought this card pretty much for the fact it matched the color scheme, and had a pretty cool back plate pre-installed, which I didn't have to order and pay extra for. Plus I got a FREE copy of The Witcher III with my purchase. Too much for Linux? I think it's perfect. Right now only using a 1680 x 1050 display, so it's not going to be worked to death.
I've used the Seasonic 520w M12II in my last two builds. I couldn't be happier with the unit, the cables etc...for the price, nothing else was remotely considered.
The rest...monitor, keyboard, mouse etc... stuff I already had.
I chose to continue using Kubuntu 14.04 it's been rock solid, and I'm able to do basically anything I need to with it...I'm still learning, and it's still fun.
UPDATE: 2/10/19 still running Kubuntu currently 18.04.2 Bionic Beaver LTS release.
