3 out of 5 eggsMissing driver for Win7 64 bit

Pros: It works. Price is good.

Cons: Device Manager complains about missing driver for PCI Simple Communications Controller when using Windows 7. MSI driver updates do not fix the problem. MSI support is impossible to contact.

Other Thoughts: It seems to work fine. I'll probably just live with the problem.

4 out of 5 eggsSolid Performer

Pros: Clean design.
Some solid caps.
I've used this board for 3 builds so far and all have been working great. No problems so far. Will continue to use these for some of my builds, especially for my Core i3 systems.
Has built-in support for legacy ports such as parallel and COM ports, but you will need headers for these if you plan to use them. This would be a perfect board if it also came in Mini ITX size. I have used both i5 and i3 CPU's with this board, but not i7 yet, so I can't vouch for i7 stability, but so far so good.

Cons: Not all solid caps.
Now this is really strange - the edge of the motherboard (the side closest to the RAM slots) does not have standard mounting holes, and only 1 at that. I had to use rubber feet to give the edge some support because there is 3 inches from the edge to the nearest mounting support - this makes the motherboard flex too much when plugging-in SATA and power supply connectors. The 1 hole it does have on that edge will not align with the case mounting (it's off by 2mm) so I can only guess that it not for using a screw mount but maybe a plastic standoff. What's up with that? Half an egg off. Newegg needs to add the video qualifications to the description (see other thoughts below)

Other Thoughts: Be aware that the built-in video will only work with the Core i3 since it is the only Core CPU with built in graphics inside the CPU (currently). Same thing for MSI's sister H55M-E33 (it's only $10 more and you get HDMI and Digital ports, but don't expect stellar graphics performance - instead use a dedicated video card. However, it's good enough for business apps).

5 out of 5 eggsGreat motherboard for the price

Pros: Lots of CPU overclocking potential, has lots of bells and whistles for a micro atx under 100 bucks.

Cons: Not a lot of space, things go on board in a certain order - CPU, then ram, then mount and plug in Sata drives, then video card. PCI-e Video card has to go in last.

Memory clocking is maxed at 1333 out of the box, you have to manually change it to go faster, which is somewhat of a headache.

Other Thoughts: I have 8 gigs of ram in this puppy and it is smoking fast. A Nvidia 5770 fits in this thing, but put in last, you've been warned!

Comes with a great instruction set. The only difficult thing was setting the ddr3 ram from the stock 1333 to 1600 which is not explained very well and this board being so new, there is not a lot of information on the internet yet.

Otherwise great board, would buy again.

1 out of 5 eggsDOA

Pros: None never got the chance to try it out.

Cons: DOA, second DOA MSI board this year, Called and rep said they had 2 other ones also sent back in DOA.

Other Thoughts: Definitely not buying MSI again. Been burned in the past by this company too, but decided to give them a chance again. Newegg's support was awesome though informed them about the issue and its getting taken care of right away. Only bummer is waiting for the new one.
