                  File No.: 333-120276

Dear Sir or Madam:

         Pursuant to Rule 461 under the Securities Act of 1933, as amended, the
undersigned registrant hereby requests that effectiveness of its registration
statement on Form S-1 be accelerated to April 11, 2005, or as soon thereafter as
practicable.

         In that regard, the undersigned registrant hereby acknowledges that:

            -     should the Commission or the staff, acting pursuant to
                  delegated authority, declare the filing effective, it does not
                  foreclose the Commission from taking any action with respect
                  to the filing;
            -     the action of the Commission or staff, acting pursuant to
                  delegated authority, in declaring the filing effective, does
                  not relieve the company from its full responsibility for the
                  adequacy and accuracy of the disclosure in the filing; and
            -     the company may not assert staff comments and the declaration
                  of effectiveness as a defense in any proceeding initiated by
                  the Commission or any person under the federal securities laws
                  of the United States.

                              Very truly yours,

                              ATEL CAPITAL EQUIPMENT FUND XI, LLC
