You'd be adding strain to the disc-spin motor when it starts to spin it, but this would be minimal and wouldnt make much differance. It may strain the laser when trying to stream data, this causes no permanent damage but means that it may have trouble reading the disc while the unit is vertical, this isnt definate so i'd say just test to see if it reads games that require alot of loading if it's fine chances are it being vertical won't cause a problem.
This is just my opinion but i really cant see anything being damaged because of this. The PS2 doesnt run well vertical but that's due to the way it grips the disc as appose to the way the GD-rom assembly has a clip on thingy to hold the disc. DC should be fine vertical.
Whats the mod if you dont mind me asking?
