: Full ATX is a waste of space and money with just 1 card in the system, Gene V has Fan Xpert 2 in µATX. Fan Xpert+ boards still good.Case
: OK, but see Mobo.SSD
: OK, personally prefer mature models.HDD
: Switch to WD Red with longer warranty and possibly better acoustics (see the SPCR reviews, my 3 TB is fantastic).PSU
: OK, but note Seasonic whine risk. See if you can get a deal on the Rosewill Silent Night 500 Platinum 80 Plus
if in the USA.RAM
: G.Skill. 2x4 GB is okay, DDR3-1600/CL9 if you're not overclocking.OS
: Win7. See Windows 8: what do you think about it?
. tl;dr for me is: no added value or benefit in desktop use, plenty of headaches, even Microsoft regret current W8 iteration.Monitor
: IPS, TN only if completely out of money. My sights are set on an Eizo Foris, but you can get away with a Dell Ultrasharp or similar. Make sure to read reviews (prad.de etc.) first.Powerline
: I've got both a Netgear and a D-Link Powerline AV ("500 Mbps", what a lie) kit in use. Speeds are around 50 Mbps average with a range of 40-80 Mbps. I'm okay with the speed loss over Gbit (100 Mbps fibre internet), as the kits are convenient and faster and more stable than WLAN (D-Link rock-solid so far, Netgear plug-through has some issues).
If you need to save money: µATX mobo, µATX case, Bronze PSU and 650 Ti. Or AMD CPU (A8-5600K maybe).Edit 1: Fixed language.
