Overall Review: Works and runs fine, but runs a little hot on cinebench (no matter what cooler or thermal paste I use). So one egg off. Water cooling is the same result as air and I suspect the IHS isnt soldered well to the cpu die; and its not worth the cost to have that professionally redone. Or maybe its silicone lottery, but ~1400 score on cinebench (where 1500+ is normal) and hitting 90 degrees in seconds is odd. But its not a huge difference, just disappointing to see below average performance on water cooling.

Pros: Good performance hardware for the price. Nice keyboard ergonomics. Mousepad is nice. Speaks and sound card is nice.

Cons: CPU and ram passed my stress tests, but furmark and games causes the laptop to freeze - GSOD Mine had a GSOD problem and when I tried to fix it by updating the motherboard bios, exactly as I was told, the laptop would then not turn on at all...completely bricked, it was. These are cheap and a seemingly good deal for a reason. Take a chance if you dare. I don't recommend it though.

Overall Review: Runs at 4600mhz xmp2.0 with a 5800x and 3090 on an Asrock A520M-itx motherboard without any issues. No cooling for the ram and this is an open case. No overclocking on anything either. Passes 4 runs of memtest86 V9.3 (I stopped at 4). Not sure why other people are having issues, but I wanted to leave a good review since this does work for me and its a good price.

Pros: 2nd Gen i7 with Optimus Nvidia 555m (96 cores) 6Gb ram (2 ddr3 slots - a 4Gb and 2Gb stick) USB3.0 AND eSata :) Full sized keyboard Mousepad is responsive and easy to use Approximately 4 hours battery life while playing with word, pdfs, and circuit design programs on the setting "Super Energy Saver" Disassembly is easy - there is a panel with a bunch of screws to remove and then you can get at all the components immediately

Cons: Only 4Gb of the ram are running in dual channel For some reason they placed the hard drive next to the audio out ports - this causes EMI which forces you to use the higher impedance Line Out over the lower impedance headphone port

Overall Review: The 555m is integrated into the motherboard. So if it goes bad shortly after the warranty, replacing it will not be an option unless you know how to solder really well This is a good option for those that don't feel it's worth it to shell out more money for more pixels on the screen. When I opened it up, I found there is one giant heatsink used for the CPU (and HD3000), NB, and Nvidia GPU; although the Nvidia GPU has its own heatpipe. PSU is a reasonable size and connects firmly into the laptop. It's rate at 19.5v, 6.15A, approximately 120watts output. So I'm not sure how much power that leaves for usb devices when the computer is under full power load. I recommend buying a portable surge protector if you plan on plugging this in somewhere like a school library. My last laptop was hit by a lightning surge, unprotected.
