I'm building a computer for a friend of mine using Core i3 530 + Asrock H55M-LE(I told him to buy this board because I want to try it with CMP^2). The board has one PCI E and two DRAM slot only, so it may be a good board for CMP^2.
I tried tampering with the BIOS setting and it can go down to 900Mhz with low voltage settings. Both CPU Core VID and GPU @ 0.843V, DRAM Volt @1.3V, others settings are similar to Gigabyte H55M-UD2H.
I tried CMP^2 on this computer (not yet fully optimized) with a pair of headphone (on board VIA sound chip was used). The sound quality is delightful. Not bad at all for this cheap MB.
Before handing over the computer to my friend, I will run the Asrock H55M-LE with my battery power supply, SSD HDD and USB DAC to see how it comnpare to my Gigabyte H55M-UD2H. I will report the findings in a couple of days.

New Gigabyte MB - miniATX format, pretty minimalistic, but I don't know if PCI-Express-to-PCI adapters work fine, could anybody clear this up?
I've just found this MB. It has two ram slots only, all Oscon Cap, 2 OZ copper but no 1394 or ESATA ports. It is somewhere in between the H55M UD2H and S2H. BIOS is F1, it should be a new board. Have anyone try it. Please kindly report.
On the other hand, I've initially listened to the Asrock H55M-LE combo, powered by batteries + regulated supply, Kingston DDR3 1333 Value ram, same as my current setup with the Gigabyte GA H55M-UD2H.
Honestly, I cannot make a direct conparison between the two boards, because my UD2H borad has been heavily modified soon after purchase. Therefore, I can only rely on my listening impression when the board was unmodified.
The Good
The P4 can be powered separetely.
The Asrock H55M-LE board was very pleasant sounding. Very good bass extension, noticibaly more bass than the UD2H, smooth vocal, highs are well extended too. Overall, the sound is very attractive.
The bad
Drum kicks are not up to speed - I have not optimized the DRAM lantency yet and perhaps this is the cause. Will try tomorrow.
Focus, depth and stereo imaging are not as good as the UD2H. It appears to have a higher noise floor, background is not dark enough.
It produced more heat than the UD2H, probably due to higher CPU and GPU Core Voltage, no setting below 0.84375V is allowed
It shut off once for unknown reason. Have to reload BIOS. BIOS is not a strength for Asrock.
NOTE
My impression with this board and the untouched UD2H is that the two board have different tonal balance, the Asrock is mid-low inclined while the Gigabyte has more clarity in all fronts. Although bass extension is as good as the Asrock, the Asrock is a little bit more powerful in bass region whereas the Gigabyte has better control and speed.
I can't say which one is better but I preferred the modified UD2H for now.
Will burn in the Asrock board and relisten.
I think you'd have to burn in the new board for a bit to make it a fair comparison.
I just thought of a tweak - mounting the board to the case using rubber washers under the board. The standard screws should be long enough if using thin washers (a few mm). Anyone tried that?
