This is another one of those builds that I did for someone else. While they were pretty receptive to my suggestions, there were some things they weren't willing to budge on. The budget was a fairly strict $500, but they insisted on 8GB of RAM, an SSD, a 1TB HDD, and Windows 7. Because of these constraints, I had to skimp in some of the other areas, which is why this build might seem a bit unbalanced.
Generally speaking, this build is meant to be a mom 'n' pop PC, mostly web browsing, storing photos and the like. There will be some gaming, but no AAA titles or anything graphically demanding (that I'm aware of).
The parts overall are pretty run of the mill, not much of note. The case was not the best. Not awful, but not that great. The intake fan is 120mm, but the exhaust is only 80mm (with a 92mm possible in the same location). I cut my finger good at one point (though I hear that's good luck), and had difficulty squeezing the HDD in with the cables, RAM, and CPU heatsink/fan. There is essentially no room for cable management behind the motherboard tray, so I did what I could, bundling up the cables and tucking them away above the DVD drive and all that. Certainly not my best cable management, but it seemed like airflow should be sufficient. The DVD drive and card reader were harvested from their old Dell, and they bought all the parts themselves, so I don't have prices. Again, I reference my opening paragraph if you'd like to criticize my parts choices and price to performance ratios. They were coming from a dual-core no-SSD unit. This one should last them a good while, and still has room to upgrade should they so choose, so while I wouldn't say I'm happy with this build, I am content.
