Yeah, parting it out may be the best course. I may even sell my i5 pc, figured maybe it would be more money on ebay since there's nothing but el cheapos here selling old core 2 duo overpriced pc's on the local craigslist here. idk, I hardly game like I used to, my pc is just extreme overkill for what I do. When I built my pc I listened to all the fanboys acting like AMD couldn't even play modern games with how bad they dogged them, I could of been just as happy with a much cheaper APU rig, hell, an old spare Athlon 6000+ 3ghz dual core with hd5670 and 4gb of ram and Vista on it was smooth to me the other week when I used it, and it only has a 400gb 7200rpm HDD, I'm starting to think SSD may even be a little overhyped unless you're a real enthusiast. I know this may not be popular opinion though >.< . I put Win 8.1 on an old core 2 quad pc I have with 4gb ram, a 160gb 7200rpm HDD and it's decently smooth
I'm honestly in the same boat as you OP, my PC never gets used besides browsing online 95% of the time. Some old BF3 Xbox 360 buddies all swore building a gaming pc would get us all to play with each other, but we all went our separate ways, so the money has largely been wasted. I do value the knowledge I've gained about PCs since 2012,but, I greatly overestimated my needs in a pc. Even being able to play stuff on low 720p settings on the intel hd4000 graphics built in was good enough for me, coming from a horrible single core sempron hp g61 laptop which can barely play minecraft
