Not Part Of DISTINCT Clause But I Do Want It Selected

I get the rows(records) I want by removing the RequestDateTime column from the Select query
 
SELECT distinct et.configname as 'Part Number',
substring(email,(charindex('@',email)+1),len(email)) as 'email ending',
u.company_name as 'Company',
u.city as 'City',
u.country as 'Country'
--,RequestDateTime as 'Date Downloaded'
from
 new_products.dbo.modelrequests et
left outer join
 cc_host.dbo.usr_list u
 on
 et.username = convert(varchar(50),u.[user_id])
where
 interfacename like '%download%'
and
 result=0
and
 u.country = 'JP'
and
 CONVERT(DATETIME, RequestDateTime, 102)>= convert(DATETIME,'12/5/2007', 102)
GROUP BY email,et.configname,u.company_name,u.city,u.country,requestdatetime

 
I want to show the RequestDateTime for the 1600 records that do get selected.
 How can I put RequestDateTime back in the resulting table output without it being part of the Distinct clause?
