The most expensive part of the build was the benchtop itself. It's a 2440x600x30mm solid timber top. I picked it up brand new for $240 and spent about another $100 on sealers, stains and varnish to get the finish that I wanted. The racing seat $160, carpet $44 and seat box <$50 was all fairly cheap to build with leftover material I had in the shed. I would argue that it would give an off the shelf setup a run for it's money in terms of comfort and practicality. I might be a tight ar*e but I can't see the value in spending over $1000 on a 1080 rig when I could build something at home for a lot cheaper.
Future upgrades will include a shifter, handbrake, and a tactile transducer (like a buttkicker).
In saying that, does anyone have a buttkicker and comment on what they are like? (not a wife I have one of those). I hear they are a great addition, particularly if you're running a VR setup?
