Put together this build for a friend and his wife, for general family use. They gave me a 650€ budget and these requirements: wifi, ODD, at least 1TB storage, somewhat decent gaming capabilities.
All parts have been purchased though Amazon Italy, and the decision on which components to buy relied heavily on which parts were on sale at the time of purchase.
A little rationale:
CPU: Overclocking was out of the question because the build has to be as much hassle-free as it gets for the unskilled users, so we decided to ditch AMD FX chips. Tried squeezing an i5 into the budget but failed, so I went for the i3 4330 for its solid single-core performance, and HyperThreading for the modern multicore-optimized games. Eventual (albeit unlikely) upgrade path available.
CPU Cooler: I consider a good cooler mandatory for ANY modern pc build. Maybe not that important for heat dissipation on stock cpus but I care a big deal about noise. GPU is going to be the loudest component anyway, yes, but during general computing, when the GPU is idle, I want the PC to be QUIET. Picked the CM T4 because was the cheapest 120mm cooler available made by a reputable brand.
RAM: Nothing much to say here. Cheap, reliable, 1600MHz CL10 8GB dual channel kit. Pretty standard choice.
MOBO: Decent cheap H81 board. Pretty basic functionalities but seems reliable and I like the Gigabyte UEFI environment. 2x SATA3 ports (+2x SATA2), front and back USB3.0. And back COM port LOL :). Only two PCIe slots but I hardly imagine more would be needed. I chose a microATX board in order to shrink the dimension of the tower a little bit. Gen2 PCI-E shouldn't bottleneck the GPU.
CASE: I love this case. I LOVE it. Cheap as low-grade garbage cabinets but sports a lot of features, well beyond its price point. Pleasing aesthetics, well-finished materials, 5x 120mm fan vents (two 120mm fans included), plenty of space for massive air/liquid coolers, filtered intakes, decent cable management options.
GPU: was on sale at ~150€, even cheaper than a gtx750ti... Runs sufficiently cool and quiet under load.
PSU: Really wanted a modular psu, but couldn't fit it in the budget. Corsair was the cheapest reputable 500W psu available with sufficient 12V current and 2x PCI-E 6+2 pin connectors. Whisper silent.
SSHD: I refuse to build a PC in 2015 without a solid state drive, period. However, the SSD+HDD combo was a little to much for the budget and also having a second drive letter could have been inconvenient for the users. Also the storage requirement precluded the SSD-only solution. So I decided to buy the SSHD hybrid drive by Seagate, having used it in previous builds. Thanks to its optimization magic, OS and most common programs are blazing fast, almost SSD-grade and waaaaay faster than HDDs.
WiFI: 802.11n 300Mbps adapter, picked a PCI-e one for mobo compatibility. I usually buy TP-LINK adapters but the WN881ND was out of stock at the time.
ODD: it works.
