Summary: This did not fit my hp desktop. The screws lined up no problem but the connections on the back of the computer did not fit in slots and I had to cut openings. The power cord could not reach the motherboard without cutting power supply box to extend wires. Also did not have a spot to plug in on/off button for computer.
If I had a generic BTX case I would build another machine with this mobo

Summary: Although the case on this Dimension 5150 had to be modified for this motherboard to work, it is a better motherboard than the original factory one (HJ054 - which has a history of failure). I would not recommend this mobo as a replacement to a proprietary system like a Dell unless you want to do some work like I did or lose some functionality like front USB slots or power on/off/sleep button.
