I am using my TF201 tablet daily and as my other computer was a cheap plastic HP laptop (dm-1, now a Christmas gift for my gf) I really missed a good desktop computer in my life (like the good old days). As I've never built a computer from scratch up before (I have had some experience in desktop computer building and half-assed modification before) so I wanted to be sure in my choice of components - after about a three week daily research period mostly from the sites Tom's Hardware, Anandtech and PCPartPicer I decided on the parts below and I am quite satisfied with the result.
It bugs my a little that I had to pay much more for the components (than in the states) but these are the best local prices I've got - shipping the parts would have cost a lot more. I've bought half of the parts from Helsinki Finland (where I live now) and half of the parts from my hometown Tallinn Estonia on my winter holiday.
I am planing to overclock the computer in the near future but I still want to keep it as silent as possible. I think I got the cables tucked away quite nicely any I love the Bitfenix Alchemy extension cables (quite pricey thou). I think I'll try to go with the positive pressure airflow using both Fractal Design vents (came with the case) as intake fans in the front and use a better exhaust fan in the back - there are good dust filters on the case and that should keep the internals dust-free. I think there's still much research to do about the airflow, cooling and overclocking just to get that good balance in the performance and quietness.
Sorry about the pictures as the computer is located in a dark corner and it's hard to take a decent picture with a crappy phone.
CPU: a really good cpu at that price. I was considering an Intel build as well but it would have bumped up the price 100 euros. I'm very satisfied with the product.
CPU Cooler: good, quite cheap and silent (at least in my case) - time will show how it behaves when overclocked.
Motherboard: cant say anything bad about it - works well and it was easy to set up. I'm not really a big fan of brown color of the board but it's dark enough to go with the black-blue theme of the build.
Memory: 2 x 4gb ddr3 1600 - that should cover all of my needs. I'll maybe try to bump it up to 1833.
Storage: SSD to make the computer faster and a regulag 1TB HDD.
Videocard: I was not building a specialised gaming computer (more like an all-rounder) but I still wanted something that could run all the latest games with descent graphics settings on a single monitor system. The budget limit i set on the graphics card was €200. I'm satisfied with R9 270x.
Case: I love the case - it's really beautiful. I was looking for a case with good visual appearance, air filters and preferably with sound dampening properties. The Fractal Design Define R4 has all of these qualities in my eyes so I bought this case. It was quite easy to install the components and there's definitely enough screws bundled with the case (could have been a couple of more zippers as well - luckily I had a bunch laying around). On a negative side I wish there were more places to tie the cables down to - there are enough on the front half behind the motherboard tray but none on the other half (you need those if you are using cable extensions like I did).
PSU: I't the only thing I regret buying at this moment because of the cables - I understood it the moment I opened the PSU box but luckily I got them hidden away quite decently. For everyone who want to build a decent PC with good cable management go with at least a semi-modular PSU. I went with this unit to get the price down a little and it came with 5 year warranty after registration on their website (which I couldn't to at first, it said the product number in invalid, but the support sorted it out in a couple of ways). Otherwise it works and is quiet enough.
Optical drive: something cheap and it works - good enough.
Monitor: I was looking for a 24 inch good all-round monitor. I was about to order a Dell U2411m but couldn't dare to risk it after reading about back-bleed problems and bad batch with yellow tint issues. Benq was my choice to go because of the anti flickering back-light and no noticable background bleed at all. There isn't many reviews about this monitor but trust me - it's good (at least for a all-rounder built like mine).
Keyboard & mouse: I'm using my old wireless Locitec keyboard and mouse now but I think there's gona be an update in the future as well.
Other parts: I love the Bitfenix alchemy extension cables as they make the build look really nice. I accidentally ordered a 8-pin PCI-E cable instead of the EPS cable but it's being sorted out right now.
Overall I must say that it was really fun to research and assemble my PC. It's been a journey and i'll make future updates when I've had time to tinker with the machine. I still need to do some research before overclocking.
I'd really like to thank everyone who has shared his/her experience over the internet about their builds since it helped my so much with the decisions. Really good communities here at PCPartPicker, at Toms hardware and at Anandtech as well.
