Shyama is my smallest PC, based on the mini-ITX form factor. I built it in September 2009 and experimented using it as a Blu-ray player running Windows 7 RC, but now I've installed a licensed Windows 7 Home Premium and hooked it up to the TV in the bedroom. I use it primarily for watching Hulu and streaming video from my main Media Center PC.
I love the small form factor, but there are always compromises, and in this case it's the fans needed to keep the CPU and PSU cool in such a small case. They're fine when the computer is idle, but loud when it does anything. The built-in wireless works fairly well, but it seems that the antenna can sometimes be blocked by the case. I have another USB wireless device with USB extension that I can use if necessary.
The name Shyama means "the dark one; black; blue" in Sanskrit. It is one more of the names of Parvati, Shiva's consort in Hinduism.
I really like the tiny diNovo Mini. It will reportedly also work with my Playstation 3 since it's a Bluetooth keyboard, but I haven't tried that. My only minor complaint is that it doesn't have every key on a normal keyboard; specifically, the function keys (F1-F12) are missing.
