My first computer would be the Odyssey 2 Game Console/Computer which I still have packed away in my attic:
The next true computer that I owned was a Zenith Transportable:

This computer had 64 mb of ram and a 7" amber monitor. Later on I purchased an Amdek 16 color monitor that was 14".
The next computer that followed was the Compaq 386s:
Compaq Deskpro 386S 386SX16, 6 meg ram, 40 mb hard drive, 1.44 & 1.2 mb floppy drives.
The computer that followed was the Alienware ALX which I currently own. It came with two 7800GTS's on a SLI with Liquid cooling. Dual Core 4800+ AMD Processor and two 7200 rpm hard drives on a RAID O and 1 10,000 rpm drive on JBOD(no RAID). I have now upgraded the videocards to one 8800GTX.
My next compute will be custom built by me in early June. Waiting for the new Nvidia GF100(400 series) of graphic cards to be released and the I7 980x 6 core processor. I'm looking to use a super computer motherboard for my next build. Everything will be liquid cooled. CPU, GPU's, Hard Drives, RAM, Chipsets and MOBO Voltage Regulators.
Peace out!
