These parts have been used heavily for gaming over the last 3 years, but they are in good condition. Neither motherboard nor CPU were ever overclocked, or used for "mining" or other compute workloads. This was a "Wintendo", strictly a gaming PC. These parts are working pulls; I was gaming on them yesterday. The motherboard is a Gigabyte GA-Z97MX-Gaming 5.It's a full-featured MicroATX motherboard with Crossfire and SLI support. You can see the full details of the board here.
It is to the best of my knowledge fully-working (I have never tested the PCIe x1 slot or the PS/2 connectors) and I have cleaned it thoroughly with compressed air. I did not get a picture of it, but I also have the cushioned I/O plate. I do not have the paper manual or driver discs, but you can download all of that from the motherboard website above. The CPU has been delidded.The processor was cleaned of the adhesive and then the heatspreader was replaced, with Coollaboratory Liquid Ultra TIM used between the CPU die and the IHS. The TIM was also applied to the "Crystalwell" L4 cache chip. To see the full specifications of the CPU. It is possible to safely remove the CPU from the motherboard, but it takes great care as the IHS is not attached.
I did not attempt to overclock it; I delidded the CPU mostly because I already had the delid tool and I wanted it to run cool, which it does. There is some minor cosmetic damage to the heatspreader; it does not affect functionality at all. Due to a firmware bug in this board that Gigabyte never fixed, you cannot use the Iris Pro graphics of the Core i7-5775C CPU alongside a discrete GPU. You can use the Iris Pro graphics just fine on their own, OR you can use a discrete GPU. However, attempting to use both will cause a hang in Windows.
Make sure the integrated CPU graphics are disabled when attempting to use a discrete GPU. Every other function of the board works just fine. However, as long as you leave the CPU installed in the board it shouldn't be a problem.
