While many of us here like to 'roll our own' when it comes to a computer, if you're looking for a powerhouse that's prebuilt, [H]ard|OCP has the M6 Sniper watercooled system from ABS. With a total of 7 external bays, you’d think this case has endless room for expansion. However, both 3.5” bays and three of the five 5.25” bays hold the reservoir for the cooling system. It has to go somewhere, and in this case we prefer to have it take up unused space on the inside rather than add additional bulk to the rear of the chassis. After all, we still have room for two optical drives. This box got high marks, and even if you don't want this particular model, ABS really seems to have it down in areas like customer support...and that's definitely something you'll want if you're not as tech savvy as some.
Might be if you're running Windows 9x. Windows XP is able to use up to 4GB of RAM (although you start getting some funky stuff past 3GB, due to various factors between hardware and software). Some games, like Battlefield 2 and FEAR run much better with 2GB, and these days, you're really going to hurt with less than 1GB.
