My previous home machine was 7 years old and worked fairly well with even modern games like Skyrim and Fallout 4 at moderate graphics. However, it started becoming unstable with random lockups. This presented the opportunity to build a new machine.
I spent a lot of time trying to figure out which chipset to go with and have some buyer's remorse. However, I'd have that no matter which type I went with. I decided on the Z170 simply because it's for the 6th Gen Intel. No other reason. The X99 would probably have been better due to the increased number of PCIe lanes and ability to have a chip with more cores; I just couldn't justify the cost for a machine that will occasionally play high-end games but mostly be used for Netflix. (I do use a Linux VM which would have benefited from more physical cores, but again, not so significantly that I could justify it.)
This is an air-cooled rig in a non-air conditioned room in the middle of a heatwave. It idles at about 28C in ambient 21C, and at 100% load on all cores at the same ambient maxes out to about 75C. Increasing ambient to 35C increases idle to 40C and load to 85C. This is done with the CPU fan, top fan, and rear fan controlled by the BIOS with default settings. The side and front fans are 100% and not controlled. (There is only one top fan but the Rosewill will accept two.)
Problems: 1) The Cooler Master Hyper 212 will have some problems fitting into the Rosewill case. It must be mounted horizontally (long edge perpendicular to the top) in order for the case's side panel fan to fit.
2) Installing Windows 10 on a fresh build using the Gigabyte Gaming 7 is -NOT- trivial. I purchased a 'system builder' Windows 10 DVD and booted up. The Gigabyte manual said to put in the driver CD when asked. The problem is, Windows would not stop asking for a driver. I'd point it at the proper driver, Windows would see it and accept it, and then come right back saying there was not driver and to insert a disk. I transferred all of the drivers and apps from the Gigabyte CD to a USB stick and left the Windows DVD int he drive. Same thing.
I finally got a Win 7 Pro DVD, installed that with no problems at all, then used Microsoft's free upgrade. This worked just fine, but the free upgrade will end soon and might not be an option for those reading this after July 2016.
3) If using Gigabyte's BIOS RAID, be prepared for slow HD access for the first 24-48 hours after installing the Intel Rapid Storage app/driver. This app will run a parity check on the RAID volume (assuming you didn't select RAID0 which has no parity) on the next reboot. This occurs in the background and doesn't effect the system other than using up some SATA bandwidth. Just don't profile or run benchmarks until this check is complete.
4) Read the Gigabyte manual carefully. It's not written well and doesn't go into as much detail as needed, but there are some things that you'll need to know before building. The most important is that an M.2 SATA SSD uses SATA Port 3. This tripped me up and I couldn't figure out why the HD I had hooked up to Port 3 wasn't seen. As soon as I moved it to Port 4, it was fine. That's when I saw the section in the manual.
5) The Rosewill case has a weird buzz coming from the front panel. This panel is also very easy to yank off when moving the computer, so be careful. I'm still trying to figure out how to get rid of the buzz. It's not bad or really noticeable unless you are right next to the machine and might not happen on all cases.
6) The 3.5" external drive cut out in the front panel of the Rosewill will pop out unless its retaining ears and bent at a sharp angle.
