Unfortunately the process preparation and installation I didn't take pictures, so I spread the finished outcome.

Configuration:

• Motherboard: ASRock E350M1 (AMD Dual-Core Zacate E350 APU, AMD A50M, PCI-Ex16)
• HDD: WD 500Gb 5400rpm 8Mb SATA (WD5000BPVT)
• ПRAM: Team Elite DDR3-1333 2048MB PC3-10600 (with radiator)
• Monitor: made in china, but good quality, with HDMI input.
• Sound: Challenger TA 5.1 + Hertz ECX 570.3

A little bit about performance. The first criterion was — the minimum energy consumption, the second — performance and the third — the minimal heat emission. The optimal variant was this motherboard with built-in dual-core AMD CPU. In tests at the maximum load this CPU consumes only 5W. The performance of CPU enough for easily play HD-video. During normal operation — it is playing music + video record from two cameras (one analog and one web) load CPU was no more than 50%. In hot summer weather, this PC surprisingly little heat emission: HDD up to 38-40 °C, CPU up to 45 °C.

Bought two KITs of xenon ProLumen Toyota with temperature of lamps 6000K (Korea).
H11 — for fog headlights, H7 — for low beam headlights
Electronic blocks on the edges are recommended to grease sealant before mounting.

For mounting xenon need take off headlights. Without removing headlights very difficult mounting xenon.
