I decided around 4 years ago that I wanted to make something a little different to bring to the Multiplay iSeries event in the UK. Over 6 month prior me and friend Lee Taylor banged our heads together to develop his idea of building a PC into... a Beer Barrel!
I found a French chap near where I work in Bristol who specialises in making bespoke furniture from old wine and beer barrels, so I approached him. He made up a cabinet style using an old French beer barrel, which we have then modified further by installing a central partition right down the centre, along with large holes top and bottom for ventilation. The rear half houses the water-cooling pump, reservoir, radiator, PSU and most of the wiring, keeping the front free for the GPU and motherboard.
Specs-wise, it's running a MSI Krait Z97 mobo, i7-4790k CPU, GTX980 GTX card, 16GB Avexir Core RAM with white led's. Watercooled by EKWB blocks; a Supremacy CPU block, and a custom fitted copper full GPU block (I bought two separate blocks and switched the covers over as the copper was only available in the smaller cover that didn't cover the entire card). Piping is a combo of 3/4" OD 1/2" ID clear rubber tubing, Rocketscience fittings (www.facebook.com/RocketScienceAU), and 1/2" softdrawn copper pipe. The total weight of the build is about 35KG.
