What’s the most important part of your PC system? Its processor? The mainboard? Maybe the power supply? You’d only have a case if you thought it’s the PSU. That cornerstone of a PC system is the most important part of the PC system as concerns what’s in the chassis, which might surprise you, but it’s definitely the devices you use to interact with a PC which are absolutely top dog.

Microsoft Wireless Keyboard 850 + Wireless Mouse 1000 Set, RF 2.4GHz USB 2.0 Dongle, AES, 1000dpi Optical Sensor, Black is rated 2.0 out of 5 by 1.
Rated 2 out of 5 by from Awful Bought this to avoid having two keyboards on the home desk at the same time, the second PC keyboard can just be left to the side and reached for when needed (keeps the desk clear'ish). Current setup keyboard/mouse within 1.5m of dongle, clear with no electronics between them. So I plugged in the dongle, waited for it to be recognised and away we go. At first everything seems to work OK but then the mouse seems to hang on the screen and then suddenly catches up. One minute the mouse is fine the next it isn't. But hey, it has a switch to turn it off. Then we come to the keyboard ... it's OK (sort of). The keys feel 'dead' and the angle feels wrong, even with the feet out at the back, but it does work. The mouse has a switch so that you can turn it off, so why doesn't the keyboard? The main advantage of wireless is that you can put it out of the way when you want to use the desk, if the keyboard stays live you have to be careful how you put it away or your PC will start working. Perhaps I've been spoilt by the previous Microsoft quality kit, I have spare Microsoft Keyboard 200 keyboards that feel so much better (they were so cheap I used to buy them for the inevitable urgent calls for a replacement to a broken one from friends). This kit is just BLAH! My advice, avoid this kit, I wish I'd just bought the cheap set instead because that's what it feels like I got. If it's only for occasional use (and you can use a trackpad instead of a mouse) buy the Logitech K400+ instead, I use one for my media centre and it works great (even has a switch so you can turn it off and stuff it down the side of the sofa).
