I agree with @qatarlivingking; nowadays you can purchase a complete gaming rig online, its up to you whether you want to upgrade it or not. But honestly, seeing your specs @nightdweller its a bit outdated. I just watched a couple of streams lately and saw a rig between 2k-3k USD which is quite good, take virgin electronics for example in villagio where i saw the alienware specs. I'm not trying to assassinate your rig but i guess you really need to give also a honest price if you want to sell it. more likely, i think its better to offer your skills on making a good rig by posting ads.
