Has anybody considered MIG welding for their mod? I'm talking about fabricating almost everything by welding it together. I know it's not going to work on modern aluminium and composite cases, but does the steel used in run-of-the-mill PC cases withstand amateur MIG welding? (drive bays, motherboard carrier, and other mounts) I'm asking this because I have a utterly bonkers PC mod that only an absolute nutter would consider... but it involves welding! All ideas are welcome!
