Planned this build to last 5 years before complete replacement, it's a higher-budget - long lasting build, I went for parts which were in the high end budget rate and had good potential for overclocking later in their life to kep them a little more relevent. (for example I chose a new unlocked i7, but not an Extreme Edition since the diminishing performance returns and price difference were prohibitive). There is room to upgrade it in the future, perhaps new graphics cards in 2-3 years.
It replaced a very old AMD Athlon 64 (3700+)/ GeForce 7900GS based setup, which was around 6 years old and still able to play recent games, even if they demanded a dualcore such as Deus Ex Human Revolution. (Although, I have a high tolerance for sub-30fps gaming and dealing with occasional stalls and problems. Many other people would have regarded it as unplayable, despite being fairly enjoyable), so I suspect this will last to that age (Or hope, since tech is advancing faster and faster).
The only major problem I had was I was doing everything in the order things were written in the manual, to be sure I didn't skip anything important, this resulted in me having to go from a more or less built system to take the motherboard out just to insert the wifi module. For some odd (And stupid)reason the insertion of the motherboard is shown in the maual before the wifi unit. I know the manual isn't a step-by-step, but that was a seriously dumb move.
Cable management with the stiff wires and the huge quantity of PCI-e power cables (4) was also difficult, but once I got it sorted it was out of airflow. It's still not pretty, but you have to remember I'm using every single socket bar one on the PSU, and all those cables take up a rediculous amount of room, even for such a large case. I think a modular PSU may have been a mistake, but it's one I can work around myself.
It is currently missing a corasir watercooler, but I decided to wait before I bought this, since I don't need to overclock it immediately and I could do with spending money on other things.
So far, it's running well. Having a little trouble with Intels poorer than expected cooler (Which has no fan guard and is generally terrible at cooling) but aside that I'm enjoying my new PC.
Feel free to ask questions, I've probably forgotten things people actually want to hear.
Ok, I know about the cable management, and I'm sure I was being over-careful not to damage my motherboard, I should be able to route more of it on the back plate, use the longer ATX power cable, and clear some airspace I'm going to place a good portion of the blame on the modular supply still, since an old one without 15 or so power connector slots and thick wire bunches would've been more maneuverable. Or if the power supply had been at the top of the case.
I'd appreciate something more constructive than "lol cablez" as a comment. Feel free to go ahead, but you're wasting your time. Those who are suggesting other parts, I'd genuinely like to know why you think I chose badly, I may learn something new.
For anyone still interested, I've been using it for a few days after work (I work a nightshift and don't get much time at home by the way, or I'd have already fixed the cabling, or tried to.) and it's been running amazingly so far. Once I redo the cabling and optimise windows and my hardrive layout (It's a mess because I have my old desktops HDD in there and it's in a lot of broken partitions for various reasons) I'm 100% certain I'll be happy for a long time to come.
