Nemosis IV
Silent and durable PC

This Antec Mini P180 micro ATX case is made of beautiful polished Gun Metal Dual Layer Panels made from 0.8mm cold-rolled Steel giving a unique mirror-like look and amazing soundproofed enclosure.

Video Card
OnBoard ATI Radeon HD7000 DDR3
VGA + DVI + HDMI output

This is an OnBoard graphic and thus has weaker 3D capabilities. Yet for most of us, it is more than we need because it has stunning 2D transfer rate due to video memory being the same as system memory. This means high transfer capabilities for HD video playback.
What is very hot is that this Nemosis IV platform can be transformed into a powerful gaming machine by adding a decent PCIe video card of your choice.

Running in idle at 35°C you have room to play (as a comparison, my laptop's Turion X2 CPU runs at 72°C in idle). Remember, it's not the amount of cores that truely makes a difference, it is the power of one core. Most of the time the critical path for a task to complete or a frame to be drawed is located on only one core and to improve true response-time, you'd better choose a CPU that has two fast cores over four slower cores.
*T base system includes an AMD A4-5300 which is 60$ cheaper and will save you money if you don't require to play games or other CPU-intensive operations.

This memory (RAM) rises above what you get in factory-made PCs. It has a low latency. Because of this low latency your applications and games will run quicky-speedy. Not all DDR3 are the same and RAM timing directly affects CPU performance: what's good having a killer CPU if it's idling half the time while waiting for memory transfer. 16GB upgrade is also possible (see upgrades at bottom of page).
