Reddit mentions of Phanteks Enthoo Pro M Mid Tower Chassis, Black Cases PH-ES515P_BK

Its not easy buying in Ireland but if your upgrading the graphics card shortly you look on ebay.ie for an older second hand one for the meantime.
The build looks good but you can save a few euros on

Memory http://www.amazon.de/dp/B00J8E92I0/?tag=pcp05-21 or http://www.amazon.co.uk/dp/B00J8E91H2/?tag=pcp0f-21

PSU http://www.amazon.de/dp/B00I64OYM2/?tag=pcp05-21

Case http://www.amazon.co.uk/dp/B011A2LWZI/?tag=pcp0f-21 or http://www.amazon.co.uk/dp/B00NZI69JU/?tag=pcp0f-21

I wouldn't skimp on the PSU or case because they'll last you if there good, though 650W is a little high for a single GPU setup and that mobo doesn't support SLI (have to pay a premium for SLI mobo) and limits memory speed to 1600. For mobo unless you want all the features of a H97, a cheaper model will be would fine. Goodluck with the build.

The build looks solid, just a few things

• The same monitor is $20 cheaper at newegg. https://www.newegg.ca/Product/Product.aspx?Item=N82E16824160167
  
• Get a 500watt 80+ Bronze PSU from EVGA, seasonic, or corsair. Modular is up to you.
  
• For case, I can suggest two that are ~$90. https://www.amazon.ca/dp/B011A2LWZI/ref=cm_sw_r_other_apa_yaORAbYJZ1R7Y https://www.amazon.ca/dp/B00NGMIBUU/?tag=pcp0f-20
  
• Keyboard, never heard of the brand, apparently cherry mx blue equivalent, sounds sketchy.
  
• You probably should get a HD unless you already have one, 250GB ssd is only enough for few games.
  
  Edit. I found a $25 network card because I don't know you're willing to spend on one. https://www.amazon.ca/TP-Link-TL-WN881ND-Wireless-Express-Adapter/dp/B0079XWMEI/ref=sr_1_7?ie=UTF8&qid=1521507801&sr=8-7&keywords=network+card
  
  Edit 2. There is a 15%OFF Everything On Ebay. https://pages.ebay.com/promo/2018/0320/7019.html
  So I found this equivalent which should be $194 after the coupon without tax or you can get other ram. https://www.ebay.ca/itm/Team-T-Force-Vulcan-16GB-2-x-8GB-288-Pin-DDR4-SDRAM-DDR4-3000-PC4-24000-Desk/201694919705?hash=item2ef5f43c19:g:GnsAAOSwa8dZ0P4~

Something affordable but with lots of space :) $70 Phanteks Enthoo Pro M Mid Tower Chassis

The P400s doesn't seem that much different internally compared to the Enthoo Pro, another Phanteks case, which is what I have. I absolutely love this case. It's a little more expensive, but depending on where your computer is, it has better front USB placement. I believe it has better airflow as both the P400s and S340 both look like they have kind of weak intake in the front.

This is the case I have so you can check it out for yourself. Also if you are a little more about aesthetics, the Enthoo also has a cut out on the PSU shroud so you can have the brand popping out!

Otherwise, they look very similar internally, I just can't tell if the P400s has the same top mount that the Entoo M does. The Enthoo has been a dream to have, especially coming from an NZXT Tempest.

Edit: parts fixed now.

You are right, the PCPP is the full tempered glass one. Mine is the regular window one.

I'll see if I can find that one on the PCPP to update. The full window is the only difference, though I didn't want to go that route since the PC is underneath the desk and also since I didn't really use any lighting stuff.

Will it fit in this case?

Would this one do? https://www.amazon.co.uk/Phanteks-PRO-computer-Midi-Tower-Micro-ATX/dp/B011A2LWZI/ref=sr_1_3?s=computers&ie=UTF8&qid=1466273030&sr=1-3&keywords=Phanteks+enthoo

76 reivews here & 219 more here both with a Q&A section. What more did you want?

Keep in mind that the fans in the promo pictures aren't always (or usually) the fans that the cases actually come with. You always have to read the specs, in this case the Thermaltake case actually only comes with 1 fan.

My personal favorite case manufactures are phanteks, nzxt, or fractile design.

I'd probably recommend something like the Enthoo Pro M as I find phanteks cases to be amazing to build in.

If you're looking for something closer in price to the other one then I'd go for something like a Corsair 100R.

Keep in mind most cases will come with at most 1 or 2 fans, if you want more fans you'll have to purchase them separately.
