Also, there is less than a hundred dollars difference in price between an i7 and an i5 (i7, i5). Not gonna get much extra from that. He can already afford 2tb+ of storage space and a cool 240 GB SSD. I haven't really kept up with AIO cooling options these days, but last I checked for the most part there weren't really many good options and there is almost no way you can get a good custom loop with $100.
Again, I stand by my point, there is little reason not to get an i7 in my opinion. Ultimately OP could go either way and get a good PC. I'm just saying that's what I would do personally.
I now remember why I left this forum, because nearly everyone here is insanely elitist and doesn't listen to other peoples opinions.
