I wanted a simple computer to play some games and do my school work and programming, but I had a very small budget so I opted into building this computer. I went without a video card because the integrated Intel 4400 graphics looked like the would support my games well and have, in fact, supported most of my games quite well.
I've been able to play the Borderlands series, Sid Meier's Civ series, and Source Mods without any lag and at 30-60 FPS so I don't regret my decision. I also opted out of purchasing Windows 7/10 Home Premium because I wanted to save money and I've had some success with Linux in the past. This will limit the number of games I can play, but with SteamOS increasing the Linux game base I think there won't be much trouble with Linux gaming in the future.
So far the computer performs well with most of my steam library and I've only faced minor problems with the OS (Currently running Ubuntu 14.04 LTS). If I could change anything I'd most likely spend less on other parts and opt into a 2GB GTX graphics card, but I would definitely still not get Windows. It simply costs much too much.
I use an old dell monitor that I had lying around as well as a dell USB mouse and Keyboard (with 2 USB hub), but they seem to work decent with gaming. The Logitech speakers where a gift and they have some trouble working with Ubuntu, but after a little work they function well.
Since I built this computer a few months ago I've decided to go ahead and add a graphics card since I have some extra money. I chose the Gigabyte Windforce 750 Ti 4GB because it had great reviews and was a pretty low cost card for the kind of power that it's boasting.
A great motherboard for a decent price, but I've had some trouble within the case. The stacked SATA ports make it difficult to plug in 90 degree cables, but it works with straight cables. I've had some troubles with the system fans starting up at first, but after a while they'll kick in and spin. Otherwise no problems.
This case has great cable support and seemed to flow well, but I don't much like having only 1 3.5" HDD drive bay. It'd be nice to have another, but I doubt storage will ever be a problem with SSDs and a TB HDD, so not a real drawback. I lover the look of the case and its proven rather easy to clean the vents.
Pretty good speakers with a pretty nice sub, but I've experienced some troubles with the 5.1 channels properly playing (yes, the wiring was correct). Still pretty good for $60 or so speakers.
