Any micro atx am2 or am2+ 6150se chipset board will work, but most have only 2 ram slots. Some work with ddr3 only, so read the specs carefully. You may also have trouble activating windows for a reinstall. All depends on which version of windows you run. The hp windows installation reads a small bios code while booting, so it won't install on a non hp motherboard even if you made backup cd's. You may need a new coa number.
