Critique my home server build

[Schadenfroh]

Greetings,

I have finished a proposed configuration for my homemade server. It will be used as a network storage drive to share documents / photographs with my friends and family back home and to host my Microsoft SourceSafe (well, the modern VS Team Server) or Subversion server.

Cheap case with < 250 watt PSU

2 x Western Digital Caviar Green HDD for RAID 1 :

2 x 2gb = 4gb OCZ DDR2 800 (is this overkill? will 2gb do?)

GIGABYTE GA-D510UD / Intel Atom D510: Mobo / CPU Combo (is this enough power to handle WS 2008?)

Software
Torn between Windows Server 2008 R2 + Microsoft Visual Studio Team Server (modern SourceSafe) or CentOS with Samba and SVN. The Microsoft software will be free via MSDNAA.

Or I could just buy this Lenovo Pentium Dual Core server (2gb of ECC ram, upgradeable to Xeon) and drop in the two HDD above, if it justifies the added cost (+~$120 with the HDDs, but left with half the ram):

* Where are you going to fit 2 x 3.5" HD's in that Mini-ITX case?
* Why buy 800GB WD Green's for the same price of 1TB models?
* For a low power server, at least buy memory rated at 1.8v, not overvolted 2.1
* The Lenovo option would give you a CPU with virtualization support, and more options for expansion.

Yikes, I must be going blind, the specs say 2 x 2.5" internal bays and not 2 x 3.5", that case is certainly out of the question.

You are correct, about the 1TB drives as well.

Thanks for the memory tip
