Oscommerce PC configurator

Computer configurator page for oscommerce need computer configurator so the average user can build his own computer out of available components. I added a field into table products. For mainboard format of this field is x1,x2,x3,x4,x5 where x1 is mb format(atx,matx,btx),x2 is cpu bus(533,800,1000,1333...),x3 is cpu socket(754,462,939,478,775,am,am2),x4 is memory slot format(ddr,ddr2,ddr3,fbdim),x5 is graphics slot format(agp,pcie). For cpu the format of this field would be bus(533,800,1000,1333...).The cpu is already sorted to category by cpu socket. For chassis the format of thif field would be size of mb(matx,atx,itx,btx...) Other components are allready sorted to categories(like agp [login to view URL], pcie grapf.c.,ddr memory,ddr2 memory...) First page should be a case select(with all available cases and their pictures).When customer selects case the next option should be cpu, then mb, then memory,vga,hdd,optical dev,...(without pictures, but with name and price) and all with a selection of quantity. All components have to be available(status=1) and have to be compatible with mbo(that is compatible with both cpu and case). At the end shoud be the sum(with taxes) and a Order button that puts all the selected components into shopping cart. It is not [login to view URL] should be finished untill end of may.
