my biggest issue at the moment is the dimensions of the case
Nothing can be done about that ATM.
You would have to buy a new case for that
Get a FULL-TOWER next time or a bigger Mid-ATX case.
And if you are willing to sell it then I would advice against the Paint Mod also.
I mean I can't get anything bigger then what I already have due to lack of space. There isn't much of a market in my area for a computer case.
