From Acer and HP to Maingear, PC makers across the board are releasing Ivy Bridge desktops before the family of CPUs makes its much-anticipated debut on notebooks. Velocity Micro is following suit, with the announcement of three customizable PCs powered by Intel’s third-generation Core processors. Starting at $849, the Vector Z70 comes standard with a 500GB, 7,200RPM hard drive, 4GB of RAM and a 2.6GHz Intel Pentium G620 CPU (upgradeable all the way to a Core i7 processor, clocked at 3.4GHz). The $999 Edge Z40 is a middle-of-the-road model, shipping with a 1GB Nvidia GeForce GTS 450 GPU, a 2.8GHz Intel Core i5-23000 and 1TB of storage spinning at 7,200 RPM. On the premium side, the Raptor Z90 is a full-on gaming machine, with GeForce GTX 680 graphics and an Intel Core i7-3770 CPU, plus eight USB 3.0 and four USB 3.0 connections.
