- the all-important TV card without which the adjective "multimedia" coming before the computer becomes somewhat confusing;
- the WiFi card without which the computer would not be able to access the Internet from our family room; and
- a $2 piece of cable not included with the case without which nothing can be done.
"Self," says I with a somewhat confident tone, "is it not possible that you might have that $2 piece of cable as a leftover from a previous project."
So I looked, and behold, it was true. Thus did I sit down for a couple of hours, screw parts together, snap cables together, and generally just have a grand, old time. I then unplugged my itty-bitty Ubuntu box and plugged the majestic, magnificent, multimedia pc into the same spot. I plugged in the cable--after a false start--pressed the button and it glowed to life.
And then just as quickly fell into the darkness of death.
I repeated this a number of times. Then I unplugged it and took it back to the kitchen table. I took the cover off with one hand while flipping through the motherboard manual with the other. Then I discovered something. The motherboard manual said that I would need a 500 watt power source and there on the PSU supplied with the case written plainly enough for me to see was 440W.
I put everything away and plugged by itty-bitty computer back in. This is a hobby. I will not make myself crazy. I will order the new power supply and wait for another rainy weekend.
