Does anybody know if there are any websites or guides that explain how to actually build your own computer? I do not mean buying cpu, gpu, etc to put together a pc but really make your own computer? Couldn't find anything useful on the web so far but I hope perhaps you do.

Everything I've found, as far as SATA cable testers appear to only be for testing the power cables, not the data cables. I know that cables are cheap, thus not making testing an absolute necessity, but I hate buying new cables when I'm not certain it's necessary. Is there an inexpensive tester...

Testing a atx 24 pin power supply out of the computer. Are there pins that can be shorted to turn the power supply on while its out of the computer?

For several reasons, I'm considering adding a drive selector switch to my desktop, but all that I've found available are designed for a maximum of 6 drives. I want one that will handle 8 drives...5 SATA HDDs & 3 ODDs. I could put all of the ODDs on 1 switch, which would make the 6 drive switch...

Just a video I created on the unboxing of the Tinyduino a popular micro controller, figured I would share :)

One of my optical drives began having problems seeing discs, either for reading or writing. I figured that it was due to the fact that it had been quite a while since I cleaned it. Therefore I dug out my Philips Cleaner disc, which is actually no more than a disc with a couple of very small...

I've got two laptops - A Dell Vostro 3330 (something like that) and a HP Elitebook 8440p. I've only got one charger - the one with the Dell Laptop. This gives 19.5V (DC) with 4.62A on the 12V rails. The HP Elitebook can use either: 18.5V;3.5A//19V;4.74A//19.5V;3.33A Does this mean I can use...
