i 'converted' the weird form factor dell optiplex motherboards into a normal mATX case. i had to angle grid the rear slots to fit the upside down graphics card and I.O ports. along with this i had to angle grind some of the hard drive cage away and make new stand off out of metal. when i bolted the board down i placed a thin piece of card inbetween to stop it shorting out onto the sheet metal i replaced the motherboard tray with. i took the power connectors and stuff like that off the dell optiplex case as it doesnt have the normal front panel headers. i soldered a switch in place of the power button. also i had to cable tie the heatsink and heatsink fan down to the board. as it used mobo standoffs to secure. once i booted it up i kept getting a message about a rear fan being missing. (i couldent change it in the bios setting) so by this point i just couldent be assed and ended up soldering the contacts together to short the fan header out. its served me well for about 4-5months. lets just say it was the most powerful dell optiplex ive been on before. then i couldent boot it up. no bios menu. and it turned out the solder id put on the fan header had melted damaging the mobo and frying the bios chip. i knew this would happen anyway but by this time i had just finished building my new pc. so guess it was perfect timing. i still have reminence of the ddr2 ram and core 2 duo cpu that powered the BEAST but unfortunatly no photos :'(
