Black Mesa Experimental Lambda Core
This rig doesn't need an introduction. However, if you're rather new to the PC gaming scene, this awesome rig has Half-Life 2 written all over it... literally. Built by German modder Butterkneter, this PC first appeared back in 2004 and contains four HDDs, two optical drives (DVD burner and DVD player), Creative Sound Blaster Audigy Gamer, a Netzteil 530W power supply, 1GB PC2100, Gigabyte's GA-7VRXP motherboard, and more. On the design front, the rig sports an actual crowbar, a panel with a built-in cigarette lighter, bullet holes, and plenty of knobs and lights to keep your eyes and fingers busy.
