[drkbike]

how would one beable to tell if a mother board is compatible with a certain tower.

im purchasing one of my friend and its in decent condition but i need to know if i can use it in my comp

Check the Form Factor. ATX is the most common 'standard' sized tower, so find an ATX mobo.
If you're building a small form factor pc, then look for Micro-ATX case and mobo.
Micro-ATX will still fit into an ATX case though.
