I have been reading the reviews here in the UK for a few weeks now as I try and spec out a new system.  I will be building it myself as it allows me to have the exact mix of components that I want.  Having said that the system you have listed is very similar, with the same processor and Z77 chip set am have decided on.  Although it specifies an Asus Skt 1155 Z77 ATX board it does not state which one, I believe there are a couple.  If is Asus it will be be a good board anyway.  

I always recon US dollar prices relate directly with UK pounds without any conversion rate.  Based on that and my research the price you have been quoted would seem to be about right.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
