New Desktop Computer before GST?

I've been always a computer guy, so when it comes to computer, I always hand-pick my own components and build it myself. It's pretty simple, and my current rig is set-up since Y2008,

This is my current rig specifications:

Mainboard ASUS P5K-PL

Intel Core 2 Duo E8400 3.0GHz 775BC 1333FSB 6MB L2

Kingston PC800 DDR2 2GB

2TB WD 3.5" 7200rpm 64MB SATA3

500GB WD 3.5" 7200rpm 16MB SATA2

XFX GF 9600GT (650MHz) 512MB DDR3 256bit

22" Samsung 2232BW 2ms 3000:1 (A+D)

Liteon 20x SATA DVD-RW Combo

EMAG ATX Casing

Cooler Master Extreme 460W

Logitech Internet Pro Keyboard & Optical Mouse

Edifier E3100 RMS 8Wx2+12W 2:1 (5" Woofer)

It is now Y2015, this machine has been running for almost 7 years now, and there are some problems.

1. Y2014 the mainboard dead, and I have to find a replacement for it. Problem is, there is no mainboard in the market then that supported the Intel Core 2 Duo socket, big problem. I hunt for so long and finally manage to find the Asrock G41C-GS that's selling for a premium price of RM229. I paid for it still, as it's' much more expensive for me to fork out cash to setup a new system.

2. Then this month, the Power Supply Unit (PSU) went down as well, but PSU is easy peasy. I managed to find the exact same unit to replace it at RM129. Other than that, it's all running well.

With 2 incidents within a year, it shows that the system is aging fast and might not able to support me for longer time, so I search out for new system to gauge the budget and price. And this is what I gathered.

Gigabyte GA-H61M-WW = RM189.00

Intel Core i5-4440 Quad Core 3.1GHz 6MB = RM614.00

Kingston HX316C10FB Fury PC1600 8GB DDR3 = RM239.00

Sapphire R7 240 2GB DDR3 128bit = RM249.00

SSD Kingston V300 120GB 450MB/450MB = RM199.00

Silverstone Essential 500W = RM169.00

Liteon DVD-RW SATA = RM59.00

Cooler Master K350 = RM149.00

AOC E2450SWD 23.6" 2ms D/W = RM469.00

Total = RM2,346.00
*note: keyboard, speakers and additioanl HDD is missing, so add what's needed.

This is a pretty decent machine to cover most basic gaming needs and definitely can last another 7 years if taken care of. However, I formatted my old rig and installed Windows 7 and it's running fine again, so don't see the point of upgrading it, so postpone my desire. Since I've done the research, so share it here for anyone that's interested to build a new rig before the GST =)
