A quad will fit in the front (just done one for a mate today). You wont be able to fit bugger all else in though so youll need to go external DVD. Allso we had to mod the case up a little to get it in.
Dont have any pics as it was all fitted and taken away today plus i cannot tell you which rad we fitted in (due to a reason).
And if you what cheap brackets "Meccano" is you best friend.
