Pentium III FC board with OST I.Q caps. Not having stability problems yet, but four of them behind the CPU area (3300uF 6.3V) are bulging out the top. Fortunately I have a new spare MB, just need to swap out boards and see if I can find replacements to try the repair. Heat is probably a consideration here as it stays on in an office where the A/C is turned off over the weekend...
