This review is from: Rosewill USB Wired Slim Desktop Keyboard & Mouse Combo Black - RKM-600
Pros: The placement and shape of the keys are perfect. There is no funny business here. Some keyboards have oddly shaped keys which can really mess up your typing. for example: often times the backspace key will be small or the enter key will be shaped funny. None of those issues here. It's very standard. The keystrokes feel pretty standard for a membrane keyboard, nothing special here, it is quiet.
the mouse feels durable. It's also optical so it should be pretty reliable. It is also symmetrical so it is perfect for left handed users also.
Cons: The lettering on the keys look like decals, they will likely wear off with enough use. The mouse is a bit narrow. For people with large hands like me it forces you to claw grip. If you have small hands you may like the shape.
Other Thoughts: I have a raspberry Pi Zero which seems to be very picky about the usb devices which are plugged into it. this is because of the power requirements of these devices. This keyboard only requires 50mA of power which is great. However the mouse draws 1 Amp. This mouse might not work with certain older computer devices or or hubs with provide less than 1 Amp of power. This might be a issue for vintage computers with usb 1.0 ports. It was a issue for my Raspberry Pi Zero. Overall this is a good combo for the price.READ FULL REVIEW
Pros: The cord is not braided, it's a cosmetic drawback, however a potential advantage because braided cords are less flexible and more likely to restrict movement.
The palm rest and sides feel indestructible. I can't say the same about the buttons, But it feels like you could park a yacht on this mouse without it breaking.
For me, the most important thing about a mouse is how it feels and responds to my movements.
I play a number of competitive shooters including counter strike source and quake 3 arena. I take my mouse pretty seriously and have even done modding to several of my mice to try and improve them. twitch-like movements and instantaneous reflexes are essential in those games which is why i prefer a light mouse. it says 85 grams ultra light weight on the box. It's not the lightest mouse i own, but it's 2nd place out of the 12 different mice i have now. The lightest is a 13 year old logitech m-bj58 which weighs 65 grams.
The Katar has a interesting design, it almost appears to be a hybrid between the older optical mice and a laser mouse, It has a optical LED light. but a modern looking 8000dpi sensor. because of this design and the way mice work i decided to test it on different surfaces, it works very well on mouse pads, cloth and matte surface's. however it has problems on glass and shiny surfaces. This was expected because its optical.
Optical and laser mice both work by rapidly taking photographs of the mouse pad surface and it compares them to determine where and how far the mouse has moved. Contrary to what most people assume, Optical mice are actually superior for consistent results on a textured surface, such as a mouse pad.
Laser mice were created because optical mice had problems tracking on certain surfaces such as glass, smooth plastics or even glossy magazine covers. Laser mice were convenient because they could track on almost anything. A laser mouse uses a smaller and more focused beam of light and can penetrate deeper into the texture of a surface. This allows it to track better on surfaces with less variety, like glossy and reflective surfaces. However, it's taking a photograph of a much smaller area of the mouse pad, and things like hair, dust, food particles, and mouse pad fibers, look far bigger to a laser sensor and are more likely to cause a error in tracking.
Optic sensors take a large photograph and can often track right over that stuff without making a mistake because the debris looks small by comparison to the rest of the photograph.
Laser mice track better in extreme precision scientific tests. however real gamers don't have a super clean gaming surface, they have a used mouse pad with frayed mouse fibers, dirt, food crumbs and embedded skin cells, sweat, and whatever else. unfortunately dust and fibers like to collect on the mouse sensor and can make portions of the photograph unreadable and leave an even smaller tracking area overall. dirt is the bane of laser mice. i often find myself blowing at the laser or trying to work a q-tip into the sensor of my laser mice when it's not tracking right, I rarely have to do that with a optical mouse. For mobile gamers, and on-the-go whatever surface available people, a laser mouse might be more convenient. But for competitive gaming on a mousepad, stick with an optical sensor. That old logitech i mentioned has been my go-to Quake3 mouse for as long as i have been gaming. I like it more than my sensi, ouroboros, and g500. I might need to spend a bit more time with the Katar to become used to its difference in weight, but it might become my new favorite gaming mouse. mouse.
Cons: The lighted logo is a bit bright.
Other Thoughts: One thing which i cannot review about a mouse is the processor and software inside which compares the photographs or "frames" and determines the movement of the mouse. You simply just have to try it and see if you like the way it feels, this is why i have so many mice laying around. This mouse seems to have all the right features. It could potentially be the last mouse i ever need. It says it has no acceleration. This is a great thing. Acceleration is bad for first person shooters, because instead of moving relative to the distance traveled, It instead accelerates and moves an additional distance based on your speed. Overall i am impressed with this mouse. It has all the right pro's and no observable cons. I am having a hard time coming up with things that could be better. I have big hands and if it were a little bit larger that might be nice. But for $40. This is a great mouse and i would have no doubts about taking it to a FPS tournament.READ FULL REVIEW
This review is from: Corsair Carbide Series 270R CC-9011106-WW Black Steel ATX Mid Tower Computer Case
Pros: Strong Durable Construction, 100% steel besides the plastic front panel, The paint is strong and durable, and has a matte finish, its not going to be a fingerprint magnet. This case is painted inside and out, with Rounded Edges, There are no sharp edges or panels to cut yourself on.
The buttons and plugs at the front are not attached to the front panel, this makes it very easy to pop off the front panel to clean out dust or to get to your front radiator or fans. You don't have to worry about disconnecting wires from the board every time you need to clean your case.
Cons: No way to mount a CD/DVD Rom Drive (becoming more and more useless today anyways)
Other Thoughts: It has support for up to four hard disks. Two of them can fit 3.5 or 2.5" drives. And the other two are 2.5" only.
The specs list maximum GPU length of 370mm, (14.5")
But the maximum length is actually longer if you don't use fans or a radiator at the front up to 420mm, (16.5") still leaving over a half inch for a power connector at the far end.
The bottom front of the case has cutouts for mounting a liquid cooling reservoir or a pump.
the shortest compatible run for a 4 or 8 pin CPU power connector is about 18 inches, which has the cable going over the motherboard.
For good cable management running behind the motherboard you will need between 22-26 inches depending on how long your power supply is.
With other cases i had issues mounting radiators at the top because the motherboard would have components or heat sinks at the top which were too tall. This case has a full 1" of space between the edge of the motherboard and the top panel. Assuming your radiator and fans together are no thicker than 1 inch, you could fit them with any motherboard. however lots of radiators are thicker than two inches. make sure this case will fit with your motherboard and ram. If you use the 140mm fan or radiator mounting holes, they begin at about 1 inch from the surface of the motherboard. and about 1 7/8" from the surface of the motherboard for the 120mm mounting holes. I test fit a Asrock Z68A E4 Gen3 Motherboard and noticed that both the motherboard heat sink and my ram were higher than 1 inch from the surface of the board. with this particular board i cannot install a top mount radiator which exceeds 1 inch (25mm)
Overall, I like this case.
