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 hard drives in this build were also pulled from old laptops to save on costs.
