we are going with a brand new RV likely a tour grade buss i want to have the option to use the computer while on the road. i do not want video cards becoming dislodged or any big bounces to effect the computer. mounting is not an issue in terms of structure as i will have this done at the dealer that will be customizing it i do how ever want to be able to change the case i consider weight an issue so an aluminum case will be a must but it should still be a full tower for 900 watt plus power supply and high end graphics card external dvr drive good idea they are built for slightly more bouncing then a internal but i will keep an internal for compatibility of installation an OS and just keep it unplugged when not used for OS install so what i am looking for is either a desk with a spring loaded shock absorber on or a wall mount clamp with a similar feature might be custom
