Here's a PC I just finished up for my friend using mostly second-hand parts. All prices I paid for or value the parts at (as I managed to get the platform in a bundle for cheap). All prices are in AUD.
My friend came to me with a budget of $1100 and wanted a gaming PC, his only requirement being that it could run FFXV really well at 1080p. I knew it was easily doable, but I wanted to build him the best PC I could in his budget. I may have gone a tad overkill, especially seeing it's only for 1080p gaming, but eh, he's my mate and I wanted him to have an awesome PC. In the end I spent just a bit under $1200 as I spent a bit extra on aesthetics - that being the LED lighting kit and the cables. I also splashed a bit more than I usually would on a brand new SSD, case and PSU as I wanted some quality assurance for him (the extra money I spent is his birthday present hehe).
I picked up the entire platform (that being the CPU, RAM, Mobo) and the H110i online for $630 posted. That included 32gb of 3000mhz ram which I took half of and put in another system. I then picked up the 1070 locally for $350. I managed to buy two from the same guy and used the other one in my other white MATX build I just uploaded (check that out here, https://au.pcpartpicker.com/b/bQnH99). The HDD I pulled from a cheap PC I picked up locally to fix and resell. Then the SSD, case and PSU were brand new, as aforementioned.
Overall I think this build came out looking fantastic, and I can't wait for my friend to come and pick it up and to see his reaction. The build isn't perfect though, and I will have to keep an eye on how it goes for him as the CPU seems to run extremely hot, even at stock where it peaks at almost 80 degrees Celsius. I suspect there's a few reasons for this - dud CPU, liquid evaporating in the cooler, bad case airflow, and very high ambient temps (it peaked at 46 degrees Celsius today in Adelaide!!!). Any of these, or a combination of several of these factors could be the cause of this issue, but it's not really a problem as my friend will only be gaming on this PC and the CPU is fine for up to 100 degrees Celsius anyway. The GPU also gets quite warm peaking and settling at 74 degrees Celsius under sustained load.
I can't really recommend this case for several reasons, including the bad temps as I've already discussed. Cable management wasn't fantastic but was certainly doable, I just had to stuff all the loose cables into the space below the PSU shroud. Most of this room is taken up by the drive bay so it was a bit tight down there. Another small issue I had was the rear side panel, which was extremely difficult to remove and to reapply. Not sure why this occurred but it was frustrating having to spend 5 minutes at a time trying to put the side panel back on. Other than that it's a pretty solid case for the price (and I mean that literally, it's a big solid build!).
This was one of the easier builds I've done in terms of gathering parts as I got the entire platform in one parcel and the rest of the parts were easy to get. No major hiccups, I'm very happy with how it turned out and am looking forward to finally giving it to my friend.
Any questions/feedback is greatly appreciated, I love hearing others' opinions :)
Edit: My friend came to pick it up and he seemed very pleased with what I put together for him.
