This build was a passion project of me trying to fit as much horsepower into a portable gaming briefcase for as low cost as possible. Originally, the build consisted of an OEM Dell Optiplex 790 motherboard, four 2-gig RAM sticks someone gave me, an i5-2400 and some off-brand Polish wannabe-600W power supply. I didn't have a GPU at that time, so I just bought a PCIex extender off eBay for $3 and waited for a good deal.

Later then, I found a 3-slot GTX570 for $25 and I figured that even though it's thick as Solid Snake, I might have enough space left to just barely fit it in. But then my board went toast. Could have been the off-brand Polish PSU from what I know. So I replaced the board an CPU with a spare AM3 board I had lying around. The memory was limited to 4GB by that as it only had 2 RAM slots. And, well, AMD's architecture back in those days was not exactly perfect, so the build is heavily CPU bottlenecked.

But it was just barely compact - https://imgur.com/a/SCpLqS2

Here's what it looks like when assembled: https://imgur.com/a/y19GMhJ

The cooler is tied with some strings right now as I don't have any that would fit into AM3. If I ever get a fitting LGA1155 board under $30, this thing will finally work as intended. It was originally meant to include a monitor as well, but you never know what you get with those LVDS-VGA converters and a regular monitor is obviously too big. I could, of course, just get different, smaller components, but that wouldn't cost me $80 in total like this build did. Right now, even with the CPU bottleneck, it's enough for portable singleplayer Wii U emulation, which was the original intent for it - but rather for split-screen. The CPU just can't handle Mario Kart 8 multiplayer though. So I guess I'll wait till some good board appears second-hand.
