Got the solution:
[FONT='Verdana','sans-serif']
Open skin1/main.css
FIND:
/*
list as multicolumn table - ADJUST HERE HEIGHT OF MULTICOLUMN PRODUCTS LISTING
*/
.products-table .product-cell .content-multicolumn,
.products-table .product-cell-hover .content-multicolumn{ min-height: 320px; }
Change min-height: 320px; to the height you need it to be.
