What is that covering your PSU?

andrewohare · 13 Nov 2014 at 13:30

Gonna try and find a long term solution though

Would the 750D be a good upgrade over my storm trooper?

Just shifted all my components from an NZXT 810 to a 750D.. I had to lose my fan controller and Optical Drive as there are less 5.25 bays and the 360 rad up top takes most of the space on the top one, although if I cut it back enough it would work.
But I read a few comments about problems with Dual Bay res in this case which made me nervous, however my XSPC 750 D5 res did fit after filing it down a bit on the sides and underneath..so overall, a happy camper.

Feels a far better quality case than the NZXT, which was overall too plasticy, although huge amounts of space.

OK , here's some more detailed shots. if you want anything specific please ask.

Top view, just to prove its a 420

i bought screws from a local shop because I was worried the ones supplied would be too long, and they didn't have black

Nice build. I'm looking to do something similar, just with a single 420. I'm just waiting for some bits to come back into stock. How thick is your 420? I'm looking at the alphacool UT60 and i know there's about 88mm clearance but I'm not convinced it will fit with my asus maximus formula vi m/b.

Also what fans are you using? there doesn't seem to be much choice for SP 140mm fans... I was looking at the Phanteks PH-F140SP, it's supposed to be pretty good.

I used this black ice radiator in the top of my case. http://www.overclockers.co.uk/showproduct.php?prodid=WC-000-BQ

It will for with the in/out openings at either end.

For fans I used these. https://www.overclockers.co.uk/showproduct.php?prodid=FG-064-AK

I have them connected to a phantechs pwm hub and set to only come on above a cpu temp of 40C so unless I'm gaming they do nothing and the only noise is the pump.
They are not silent however so you may want to get one to try first.

Thanks that makes things a lot clearer. i pulled the trigger and ordered the 750D and a nexxos xt45 360 last night along with some fans and other stuff... i guess i could still change the order as it hasn't been processed yet, as the first thing i plan to do is rip out the optical bays anyway.

Pvt_Ryan · 5 Jan 2015 at 18:28

No worries, Glad i could help.

If you need anything else feel free to PM me.

I've got 2 of those fans on my magicool 280, they're really good. If I stay with 140mm I will definitely reuse them.

bipolarbear · 7 Jan 2015 at 15:28

So I decided to go 420 after all... changed my order and the alphacool nexxxos xt45 420 arrived today along with a bunch of other stuff. I've even started a build log!

IceShock · 8 Jan 2015 at 13:36

Huston we have a problem.

Looks like iv got a small spider inside my case somewhere, Noticed these webs when I went to dust my case out last night, I couldn't see the spider anywhere though

With a bit of luck its just been sucked into a fan and obliterated lol.
But it got me thinking, if a spider was to touch anything electrical, could it cause something to short out?

VincentHanna · 8 Jan 2015 at 15:09

I recently put together one of these. Was very easy to work with.

Rig is:
Intel i7 Haswell-E 5930k
Asus X99-S Motherboard
GeIL EVO Potenza 16GB (4x4GB) DDR4
Sapphire AMD 295x2
Sapphire AMD 290x
Swiftech H240-x CPU Liquid Cooler
Samsung 840 Evo (256GB) SSD
Samsung 850 Pro (500GB) SSD
Toshiba 3GB 3.5" HDD
SuperFlower Leadex Platinum 1200W PSU

My H240-x hasn't actually arrived yet, so am using a Seidon 240m until then.

Iv totally ignored that design and fitted my SSD where the square hole is on the mobo tray and put my hdds there where ssd's go

How do you get your GPU's to stay? like that? Does it keep them cooler? Cheers.

I used cable ties to the pci-e brackets, and I use a old xbox 360 pad joy stick to prop it up also. its sturdy as a rock it aint movin nowhere.

And yep, before I did it, the top gpu used to get to around 80c or something and bottom one was 65c tops, now, both cards are 100% identical temperatures, most gap difference iv seen between the two is 1c, they both averaged at 65c but that meant I could overclock them further iv upped the volts and clocked them up a lot higher than I could before, and they both sit nicely at 70c all day long in games.

check out my project log in my cig for more info.

Heres mine. Should have been tri-fire but couldnt get the third to fit.
(My own fault for not wanting to use the EK bridge)

upload gif from url

420mm in the roof, 140mm at the rear and a 280 in the front.

No mods are needed to get the 420mm to fit either.
