Does this go with my pc parts? (size)?

All coolers are designed to clear "normal" sized parts ( ie RAM, and Graphics cards) However, firstly, it depends on if you have heat spreaders on the RAM you are going to use. Some RAM designed for gaming have high heatsinks above the RAM cards for cooling. This may interfere with some CPU coolers. Secondly, its really all about the width of your case, more than anything else. If you have clearance in your case, and clearance on the height of the RAM, your all good. Most ATX form factor parts are made to standard sizes and generally work together.
