According to the
motherboard specs on Intel's website, the MB that Tom's Hardware used in that build does support up to 16GB of RAM.
If we follow the TH build model of using only Amazon and Newegg, here is what I am coming up with for parts/prices:
Loop LP-2150 (CAP08LOOPAIO) for $264.60 + $15.77 S&H (Amazon)
Intel Core i7-2600S for $308.99 (Amazon)
Kingston 16GB DDR3 1333 Model KVR13S9K2/16 for $72.99 (Newegg)
Intel DH61AG Motherboard for $119.99 (Amazon)
Intel HTS1155LP CPU Cooler for $26.47 (Amazon)
Samsung SN-208BB (DVD Burner) for $23.99 + $4.99 S&H (Newegg)
Western Digital Scorpio Black WD5000BPKT 500GB HDD for $70.49 (Amazon)
All told, counting S&H estimates but no tax, this totals $908.28... Pull out the DVD Burner and you are still sitting at $879.30.
In a nutshell, removing the WiFi card, Keyboard/Mouse combo, and the DVD drive covers the upgrade from 4GB to 16 GB of RAM and any cost increases that have occurred since the article was written. What is killing the price here is the $100 jump from the Core i5-2400S (priced at $200.99 on both
Amazon and
Newegg) to the Core i7-2600S. Drop down to the Core i5 and your are exactly where TH was in the original price from the article. Amazon and Newegg both appear to be pretty competitive (if not the lowest then within a couple dollars of the lowest priced website for each part) so shopping elsewhere is unlikely to shave much more off the total price.
