i built this to replace my old htpc and to have a go at pc gaming before deciding if i should get a ps4 or not. this is running ubuntu 14.04 and will be used for browsing,streaming,light gaming and storing my blu-ray/dvd collection. i only over clocked the g3258 to 4ghz and didn't try any higher because i was worried about the heat in a small case, I've ordered a larger case fan so will try to go higher when it arrives. below ive listed the reasoning behind my choices and would like to apologise for the poor photos (only have a camera on my phone), i will try to take some better ones once the new fan arrives.
cpu; i bought this for the value and upgradeability. i currently dont need more than a dual-core and if i do its an easy upgrade to i3/i5/i7. £50.49
mobo; was the cheapest mitx lga1150. £47
memory; came from old htpc. £0
storage; came from old htpc. £0
gpu; went with nvidia because there drivers are better on linux and the 750ti because my tv is only 720p it should give me enough performance to try pc gaming. £103.99
case; i wanted it to have a small form factor and to take standard size parts. £24.99
psu; came from old htpc. £0
this build was easy to put together (even with the elites lack of cable management) and only cost me a total of £216.47.
future upgrades; i will be geting a ssd at some point and maybe an aftermarket cpu cooler. the cpu/gpu/memory will be upgraded if/when i decide i need better.
