First off, I'm 15 and I don't have a lot of experience building high end computers like this. That being said, this was a great build! It was very easy, and the end product was awesome! I use this primarily for gaming and programming although I do like to mess around with virtual machines (I still use my laptop for school work because it has all my old files on it).
I do a lot of gaming (through steam) like CSGO, ARMA II CO, ARMA 3, Civ V and FTL. I also play minecraft and WoT occasionally.
I plan to OC the GPU, I just haven't had time yet because of school. I did OC the CPU though to 4.5Ghz (and increased the core voltage to 1.1200 I believe). I also am going to word a backup hard drive, which I forgot to order initially. My two SSDs are in RAID 0, for extreme performance. (it boots in 9.7 seconds from pressing the power button to desktop, with about 130Gb on the RAID array). In the future I plan to upgrade my mouse and my keyboard (I just bought a thermaltake eSports headset also) and make some sleeved cables for my PSU. Also I would like to get a third monitor (run games in surround, and for programming have source code, compiler output and header files/database on separate screens). That's the only reason I went with the 4GB card, not the 2GB one.
I haven't had any problems yet, although I was worried about a few bad reviews concerning the OCZ ZX850 being DOA, it worked wonderfully right out the box. The only minor problems I had were that the 8 pin CPU cable was just barely long enough forcing me to wrestle it into place, and that the 24 pin ATX connector seemed to have a capacitor wedged in on the end that connected to the motherboard, forcing the cable to stick out farther than I wanted. The only reason I went with this PSU over the corsair AX850 was because I got it for $100 after some very extensive MIRs.
I was overall pretty proud of the cable management, although the state of the space behind the motherboard isn't ideal.
This was my first build focused not only on functionality, but also on aesthetics. I have rebuilt a few servers, and I have a little group with my friends were we rebuild computers out of old parts and give them away to people who need them, but this was something a bit different. Also WAY more high end than anything I've built before...took me forever to save up for this (I have a job).
Lastly, I got the parts over the holiday sales, and the total was something around 1900 with the MIRs, so the price shown here isn't quite accurate. Without this site I am very sure I wouldn't have been able to do a build like this, because it would be too much work to compile prices for each part from many different sites, thanks so much!
Very lastly I named it M-Zero after the supercomputer the Chudnovsky brothers built in their apartment to calculate Pi.
P.S. The pictures seem to be in a randomized order, sorry for that...
EDIT: Got a Corsair M60.
