This is my HTPC. Used for some light 4K gaming and movies. The Deepcool Gabriel cooler which is 60mm tall fits perfectly in the Silverstone ML08 even though the maximum cooler height according to Silverstone is 58mm. I recommend going with blower style GPUs if you plan to lay the case flat to prevent overheating. In vertical orientation, the GPU style of cooler doesn't matter as long as the GPU compartment is on the top side. There is a Panasonic slim bluray drive in this build that was pulled from a laptop. I couldn't add it to the parts list cause there is no option for optical drives. The RTX 2080 was pulled from a Lenovo pre-built that costed $700 because Lenovo made a price error on their site. The 450W Corsair PSU is actually sufficient to run a 9900K and 2080. The 9900K is running stock with multicore enhancement enabled and the 2080 is slightly overclocked so it reaches 2050MHz core when gaming. RAM is Micron E-die that's been overclocked to 3600MHz CL16.
