A refurbished Dell with a decent graphics card purchased from Newegg may be the cheapest way to get a decently-capable gaming system, but your budget isn't impossible to meet with new components purchased from Newegg.

I believe that we can find some alternatives that may better fit your budget.
We might try to get a slightly faster Core i3-2120 processor for $3 more than the Core i3-2100:
122½ + 130 -17 combo GA-Z68MA-D2H-B3 + Core i3-2120
or $94 + 130 -17 combo P8H67-M LX + Core i3-2120
Here's a motherboard + RAM deal if you choose to go with the Core i3-2100:
$112½ + 43 -10 combo GA-Z68MA-D2H-B3 + 2x4 GiB PC3-12800
There are some super-cheap LGA1155 motherboards based on the H61 chipset. Something like the
$63 ASRock H61M-GE and 2x2 GiB of memory for
$20 could let you get by within your budget without giving up on a
Core i3-2100.
You could save a few dollars over the Radeon HD6850 in the Econobox. I've had excellent results with
Sapphire cards over the years, but you could get one from
Gigabyte (820 MHz) for 150 -20MIR or
HIS for $140 -10MIR.
$7 cheap USB keyboard
or $13 PS/2 keyboard
or $20 Media keyboard
The really
obvious opportunity to save money in the Econobox is with the case and power supply. What can we live with for less than the $130 that TR's staff spent on their selections?
$80 -10MIR Antec Three Hundred + Basiq BP430
If you take this first option and call it a day you're $50 ahead with the possibility of a $10 rebate that may or may not be fulfilled.
Without an included power supply, here's a good value:
$50 -10MIR Antec Three Hundred Illusion
You're stepping down a whole lot in quality if you go with one of the super-cheap micro-ATX cases for
$35.
Here are three 80+ power supplies that are cheaper than the selection in the Econobox:
$50 -10MIR Antec EarthWatts EA-430D
or $47 -20MIR Corsair CX430
or $48 Antec Neo Eco 400C
